How to Open Dell Precision M20 Battery & Replace the Lithium Ion

2010-02-21T22:49:00.000-08:00

Laptop batteries, like all rechargeable battery packs, lose their charging capacity over time. Because new laptop batteries are expensive, replacing the individual cells inside the battery casing can save a lot of money. However, rebuilding a battery sometimes does not work as expected, so it’s important to be willing to purchase a new laptop battery if the procedure fails.

Dell Precision M20 Battery 6 cells 4400MAH [http://www.udtek.com/dell-precision-m20-battery-cells-4400mah-p-24071.html]

Now I will show some steps about How to Open a Laptop Battery & Replace the Lithium Ion

Step 1

Allow the Dell Precision M20 Battery to run down completely. Turn off your laptop, then remove the battery. Write down the model number located on your battery to help identify the type of Li-ion replacement cells you need to purchase.

Step 2

Split open a small section of the battery pack (at the seam) with a screwdriver or craft knife. Continue to pry the plastic case loose moving around the outer edge until the entire top is free. This may take a bit of force.

Step 3

Note the number of cells inside the case (usually four to eight). Write down the part number and voltage information printed on the cell casings. Draw a diagram showing the arrangement of the cells and how they are connected, or take a few photos to help with reassembly.

Step 4

Purchase the correct number and type replacement batteries from a local or online dealer, based on your battery model and cell specifications. Six Li-ion cells typically cost around $30 to $40.

Step 5

Carefully remove each cell using a craft knife and wire cutters as necessary. Each battery pack is different, but the cells are usually wrapped in a plastic casing with metal contacts attached to one end. Lay the metal contacts, wires and casing material aside.

Step 6

Use double-sided tape or a solder gun (only if necessary) to attach the metal contacts to the cells and circuit board. When finished, the old cells should be completely stripped (naked) and the new cells should look like the old ones as much as possible.

Step 7

Place the new cells inside the case, referring to your diagram or photos if necessary. Glue the battery pack top back on. Charge the new notebook battery for at least 24 hours before using it.

My HP 239427-001 Adapter is not Working for me

2010-02-09T18:03:00.000-08:00

A non-functional hp 239427-001 adapter can cause big problems; especially if the computer’s battery is low or drained. In addition to preventing you from getting your work done, it can also be an electrical shock or fire hazard.

Troubleshooting a non-working adapter 239427 001 can be difficult because there are several factors that could be at fault if the computer is not getting power. If you are at the end of your rope, there are a few hints to help get your computer up and running.

Laptop computers run off battery, or DC power. DC means “Direct Current,” and refers to the way current flows from the source. Direct current is basically a continuous and steady stream of energy. The adapter that came with your laptop computer is known as an AC adapter, which converts the Alternating Current supplied by your wall outlet into the Direct Current that is required to run your laptop. Alternating current does not flow as a steady stream.

A big cause of laptop adapter failures is cord crimps. These can occur when an office chair with casters rolls over the cord on a hard surface. The conductor of the cord can eventually break under the stress of being rolled over. If the cord or insulation is not completely severed, it may not show where the short has occurred. Since most adapters include an LED that will light up when the device is plugged in, a good indicator that there is a short would be an unlit LED.Any time the adapter has cuts in the insulation of its cord, or is otherwise missing pieces of its insulation, it should be replaced immediately. Bare wires carry a risk of serious or fatal shocks, as well as possible fire hazard. Do not attempt to repair your AC adapter. Contact the laptop’s manufacturer or seller to find information about a replacement adapter.

The portion of your adapter that does all the work is colloquially referred to as the “brick.” The brick is the heavy box that sits between the wall and your computer and is connected by a permanent cord and one that may be removable. The brick, for all its heft, contains some delicate components, and can be damaged fairly easily if it is dropped from a considerable height. Generally speaking, if the brick stops working, the LED that indicates power will not light. If the brick portion of your adapter is not working, you will have to replace the adapter. Contact your computer’s manufacturer or the seller for information about a replacement adapter.

The point on your computer to which your adapter connects is not prone to failure, but, being soldered to the motherboard with little other support, can break. If your computer only powers intermittently, or you have to “wiggle” the adapter to get power, there’s a good possibility that the power input on your computer has broken. This is not an easy or quick fix; you may need to replace the entire motherboard, depending on your computer model. A technician should be able to diagnose the problem and give you a price quote on the repair. In some cases, the computer may not be worth the price of the repair.

The easiest way to test your laptop ac adapter is to plug it in. In addition to the adapter’s LED, there should be an additional LED on your computer to indicate that the computer is getting power from the outlet. If neither of these LEDs lights, then there is definitely a power problem. If an identical, “known good” adapter can be obtained, connect it to your computer. If the computer gets power from the new adapter, then a replacement adapter will fix the problem. If the computer does not get power from either adapter, there is probably an issue with the computer. At this point, it is recommended that the computer be brought to a PC repair technician for diagnosis.

Jury-rigging should never be attempted, due to the risk of shocks, fire and damage to the computer. Do not use another computer’s adapter if it is not the same model or brand, even if it fits. Failure to match input and output voltages on laptop adapters could damage the computer, the adapter or both. Contact the manufacturer or the seller of your computer for information about replacement adapters.

If you cannot find a brand and model-specific replacement adapter for your computer, it may be possible to purchase a laptop universal power, which includes multiple, interchangeable tips. You will need to find one that matches your original adapter’s wattage, and it should also include a matching or switchable voltage output.

Toshiba x305 adapter can not fully charge the laptop battery

2010-02-08T18:05:00.000-08:00

Does your Toshiba Qosmio X305-Q701, or some other Toshiba POS randomly shut off and not fully charge the laptop battery? This is apparently a very common problem with these notebooks. When I had to fix my friend’s laptop I searched all over the internet for a solution. I found quite a few forum threads and laptop reviews discussing the issue but no one actually fixed it themselves. Lazy bastards. Most of these folks were having them sent in for warranty work and having the entire main boards replaced. This is a ridiculous waste of money for someone. I did see an ad for some computer repair place who was charging $200 to fix these, which is a total rip off. They were replacing the jack (claiming $20 just for the part!!) which is not necessary (at least not with this one). Well, I am really cheap and I didn’t want to deal with the time or BS of having it shipped (the warranty is expired anyway), so I fixed it. Cliff’s notes at bottom.

The power led on the front would flicker when the Toshiba x305 adapter was plugged in. I could wiggle the power cord and it would change the nature of the flickering. Sometimes it would stay on continuously and sometimes it would shut off depending on the wiggling. This behavior had the obvious side effects of shutting the computer off and never really charging the battery. Oh how irritating.

At first I thought it was the power cord. I mean I could wiggle the cord and it made changes to the flickering, so why not? After testing it with the volt meter it seemed to be good, good enough to not spend ~$85 on a new power cord. What else could it be?

The x305 adapter jack in the machine turned out to be the culprit. Well, sort of. Technically it was the connection between the jack and the main board. Yeah, just a stupid connection. Not the whole motherboard like the corporate “customer service” reps want you to think. See, the jack has the positive connection coming out of the back and directly into the board with a little weak solder joint keeping the jack from rocking back and forth. When the laptop is subjected to normal amounts of power cord wiggling it breaks the weak joint and screws up power delivery. You can test this by plugging in the laptop and pushing the end of the cord (where it goes into the computer) in different directions while watching the green power light. Mine broke mostly on the top joint and so the light would be a solid green if I pushed the cord end UP (thereby pushing the connection back together), and would totally turn off when I pushed the cord end down.

You can view the backside of the jack by popping the little panel thats above the laptop keyboard (it also goes over the screen hinges):

You can plug the computer in and wiggle the cord end to see if there is a visible crack. Mine had a visible crack when i pushed the cord end down. The picture above, however, was taken after I fixed it, so I have no pics of the crack.

Ok, so now you have to fix it. This is extremely easy. If you have ever soldered, you can do it. Take the laptop apart. I used this guide here which is really good. Just get the main board out so you can solder on the bottom of the jack. Once the board is out you just solder the bottom of the + terminal of the jack (the part of the jack that goes into the middle of the cord). Then solder the top. I tried to make the top solder joint as beefy as possible so it takes a while before the problem happens again. i.e. solder the circled terminal on top and the corresponding bottom terminal:

Power stuff on X305-Q701 went to shit. Wasn’t the power cord. Was the + side jack connection to the main board. Take apart laptop, take out main board, re-solder on the bottom AND on the top of + connection. Put it back together. Enjoy the not-sucking laptop.

My Dell laptop has a power problem

2010-02-07T19:16:00.000-08:00

My Dell laptop has a power problem.

The Dell Precision M20 Battery stops charging when I move the power cord on the DC adapter. When I start moving the cord left to right, the power LED light on the front goes on and off and the battery charge LED goes on and off too.

I removed the precision m20 battery and tested the laptop again. The laptop starts fine from the DC adapter when the battery is removed, but as soon as I start moving the power cord the laptop shuts off. It looks like the laptop looses power immediately.

If you have a problem like that, most likely it’s related either to the power adapter or the DC-IN power jack.

First of all, I tested the laptop power ac adapter with a multimeter. The power didn’t cut off no matter how badly I moved the cord. The power adapter output voltage was 15.45VDC all the time. That means there is nothing wrong with the power adapter and most likely there is a problem with with the power socket inside the laptop.

Now I’m going to test the power socket inside the laptop.

In order to access the power socket I had to disassemble the laptop and remove the top cover assembly with the display.

You can find disassembly instructions for many HP, Dell, IBM, Lenovo, Sony and Toshiba laptops in these service manuals and guides.

In the laptop I was fixing (Tecra M2) the power jack is attached to a DC-IN harness and this harness can be unplugged from the motherboard.

As you see, I removed the DC-IN harness from the motherboard, plugged in the power adapter and tested continuity with my multimeter as it shown on the picture.

When the power cord is still, the voltage output is 15.45VDC, the same as on the plug.

But as soon as I start wiggling the plug inside the jack, the power cuts off and voltage goes to 0. It means, the power harness is bad.

The problem was fixed after I replaced the defective DC-IN harness with a new one.

In some laptops the power socket (DC jack) is soldered to the motherboard.
If the battery stops charging when you wiggle the power plug inside the jack, either you have a bad power adapter (test it with a voltmeter) or the power jack is broken or loose.

You cannot simply unplug the jack and replace it with another one. You’ll have to unsolder the old jack and solder a new one back on the motherboard as I described in this post.

If the power jack is not broken but loose (not making good contact with the motherboard) you can resolder the old jack without replacing it with a new one.

If you want to buy a new one,you can see more information from http://www.udtek.com

Some tips to repair toshiba tecra 9100 adapter

2010-02-05T20:04:00.000-08:00

The Toshiba tecra 9100 adapter gets pushed into the laptop base so it feels loose.I don’t know if it’s a poor design or people just not careful enough with their laptops, but the Toshiba ac adapter in these models breaks very often.The power jack and mounting brackets on the base assembly got broken.

Toshiba Tecra 9100 AC Adapter 75W 15V 5A

Even if you replace the broken tecra 9100 adapter jack with a new one, it will not stay attached to the base. If you send a laptop with a damage like that to a repair shop, they will recommend replacing the power jack harness and laptop base. This repair will easily cost over $200 but I have a better idea how to fix it for $3 without replacing the base assembly.

What can you do to fix the power socket?

1. If the base assembly is OK, but the DC-IN jack is broken, you’ll have to replace the DC-IN power harness.

2. In the worst case scenario you’ll have to replace both parts, the base assembly AND power jack harness.

3. If the power jack is OK but the base is broken, you’ll have to replace the base assembly, which means you’ll have to disassemble the whole laptop.

I will replace the original plastic jack with a generic metal jack purchased at RadioShack for about $3. The RadioShack part number is 274-1576. You can order this jack online or pick it up in a local store.

Laptop power socket

There is a gap between the power jack and laptop base and when you plug the laptop ac adapter inside the jack it feels very loose. In some cases, the power jack disconnects from the laptop base and you cannot plug in the power adapter at all.

In order to understand what’s going on it’s necessary to remove the top cover and take a closer look at the power jack.
As you see on the picture below, the power jack is not seated correctly and separated from the laptop base.

Mounting bracket broken:
But in many cases you have both parts broken, the power jack and base assembly.

Power connector broken:
In other cases, the DC-IN power jack is OK but the laptop base is broken. The power jack mounts between two plastic brackets inside the case. If one of the brackets is broken (the left one in my case), the DC-IN power jack will not seat correctly.

Power socket not seated properly:
In some cases it happens because the DC-IN power jack gets broken.By the way, if your laptop is still under warranty, dell might fix this problem at no charge. Call them first or take the laptop to the authorized repair center.
If this modification works for you, please mention the laptop model in the comments. or you can buy a new one from this website: http://www.udtek.com .

Dell U4873 Battery Guide

2010-02-03T18:44:00.000-08:00

Notebook batteries are common topic of discussion, and the vast majority of questions about them deal with prolonging their lives. There is a lot of information about Lithium Ion (hereafter Li-Ion) batteries to wade through. There are a lot of misconceptions floating around as well. This simple guide addresses the most common notebook battery questions and concerns.

Your notebook battery such as Dell U4873 Battery will deteriorate over time whether you use it or not. Although the Li-Ion industry does not publicize this fact, your battery’s clock began ticking the moment it was assembled. The elements inside your battery slowly react with each other, eventually rendering the battery unable to supply the required power to your notebook. In addition, your battery is rated to last between 300 and 800 charge/recharge cycles. It will gradually lose charge capacity rather than abruptly fail to power your notebook.
How long will the battery last?
The general consensus is that notebook batteries(u4873 battery) last one to three years. While you can slow the battery’s aging and loss of capacity, you cannot stop either decline. The temperature of the battery, combined with the amount and nature of its usage contribute significantly to your battery’s lifespan. You can ease the aging process with some care and maintenance.

Nature of Usage

Li-Ion batteries do not suffer from the memory-effect (requiring complete discharge before recharging to avoid loss of capacity) like older rechargeable batteries. Regular full discharge/recharge cycles result in an increased loss of capacity per cycle. A series of partial discharge cycles are better for Li-Ion batteries than a single full discharge. You should, however, calibrate your battery routinely.

Temperature

Lower temperatures slow down the self-discharge (loss of charge while disconnected) and aging process of the elements within your battery. Therefore it follows that higher temperatures shorten the life of your battery. Leaving your battery connected while on laptop ac power adapter causes the internal temperature of the battery to rise. Removing your battery and storing it in a cool, dry place will help to slow the aging process. Keeping your notebook in a hot environment is also detrimental to your battery.

Amount of Usage

The Lithium-Ion batteries used in notebooks are rated to handle between 300 and 800 charge/discharge cycles. Some of these cycles are used when you leave your battery connected to your notebook while on AC power. On AC power, the notebook will routinely “top-off” the battery when its charge reaches predetermined levels (i.e. 95%). Removing your laptop battery and storing it in a cool, dry place will help to preserve some of these cycles.

Tips to Maximise Dell Inspiron B130 Battery Life

2010-02-02T19:39:00.000-08:00

Laptop batteries are designed specifically for different laptops brand as well as models. Today laptops are powered by lithium ion batteries. Lithium ion batteries are lighter, have a better power-to-weight ratio,have a longer usable life, can hold a charge longer, and do not have the memory effect to fail prematurely.

Lithium ion batteries(such as Dell Inspiron B130 Battery and dell precision m60 battery ) are also inexpensive to manufacture as compared to the earlier generation of nickel metal hydride batteries. The only shortcoming about lithium ion batteries is as they contain lithium salt dissolved in a highly flammable solvent, there are chances of overhead which can result in short-circuits or even blow up in flames.

It is a common fact that all laptop batteries have provision for limited time of power supply. A good bargain is to check the battery power while buying a notebook. Here is one instant tip to optimize the battery settings in accordance with the energy saving mode of your notebook. These settings will put the hard disk into sleep mode whenever the workload is less and it will reduce the notebook microprocessor performance in order to maximize its battery life.

From the system preferences mode of your laptop, select view menu, then choose energy saver option from view menu. Right click on show details option and choose battery power from the pop-up menu. Finally choose longest battery life from the energy settings pop-up menu.
Tips to optimise your notebook batteries are described in the following:
It is a good investment to add more memory to your laptop as it saves battery power by reducing Windows’ dependence on the virtual memory swap file on your hard disk.

It is better to keep your laptop on standby mode when not in use for certain amount of time. Standby mode ensures all current info is saved in RAM with minimum consumption of battery power.
Charge your laptop battery frequently with a battery charger or AC adapter. It is very important to clean your battery’s metal contacts every couple of months to make it dust free. You can use a cloth moistened with rubbing alcohol to clean your laptop battery.
Try to set the screen brightness of the LCD panel of your laptop to the lowest comfortable level as very bright screen tends to consume more power from your battery.

Similarly it is better to get rid of the outer peripherals such as printers or digital cameras as they can still draw power from your laptop battery even when they are not used.

Turn of the unused features and technologies of your laptopo which are not frequently usable. For example, it is better to eject the CD or DVD when you are not using them as the optical drive has the tendency of reading CD or DVD it finds very often and this process consume extra battery power.

To save power, it is good idea to turn off the AirPort, Wi-Fi, IR radios and Bluetooth option when it is not required to use. Virus scan should be set only during the time you are usually plugged in as full-disk virus check by the hard drive and CPU consumes additional power from battery.

Opt for the power console applet to customize the power profiles on your laptop. Do not worry in case your notebook does not have power console applet option for most of the operating systems (starting from windows 98) have Power Options utility in Control Panel.

Turning off or at least disabling the PC Cards, FireWire devices and USB when not in use also saves battery power. In fact, disabling modem, network cards and USB ports consumes less battery power even when they are on. These devices are easily disabled in device manager.
You can use power saver option of your operating system to adjust the CPU processing power. Optimum CPU processes consume additional battery power and hence should be avoided if not required. Stop the auto start applications on your laptop, so that your laptop`s CPU can be stopped from doing unnecessary work.

With the above mentioned handy tips, you can truly increase the battery performance of your laptop.

Tips of Hp 239427-001 Adapter

2010-01-28T18:34:00.000-08:00

An ac adapter for laptop allows a laptop to be plugged into a standard wall outlet. It converts the “AC” of a wall outlet to “DC” so the laptop can draw power safely while charging the battery.

Usually, an laptop ac power adapter is built to last for years, but sometimes it does not last as long as planned. When caring for or replacing a faulty AC adapter, there are a few things to keep in mind in order to maximize its usefulness and compatibility.

Not all AC adapters are created equal. Some will have differing input and output voltages which makes choosing the correct one frustrating. If you are replacing a laptop’s adapter, always check its specifications to determine the power requirements. Also, laptop computers have different sized DC plugs, so make sure that the adapter that you buy will fit. Many universal AC adapters come with interchangeable plugs to prevent this problem.

While it is normal for an AC adapter(hp 239427-001 Adapter,Toshiba x305 adapter) to get warm to the touch while plugged in, any other signs of trouble may require immediate action. If your adapter is making a high pitch noise, replace it. If your adapter stops working completely, it may be a sign of a bad transformer or a wiring issue. If you fancy yourself an amateur repairman, keep in mind that it is generally a bad idea to open up the AC adapter for any reason. In addition to being notoriously difficult to open (without a hacksaw), the internal components can deliver dangerously high voltage levels to inexperienced repairmen.

An AC adapter’s(adapter 239427 001) secondary function is to charge a computer battery. A full charging session takes around two hours or longer if you use the computer during that time. If the battery is completely dead, you may need to leave the adapter plugged in for a few minutes before you turn on the computer.Avoid exposing an AC adapter to prolonged periods of extreme heat or cold. Doing so could damage the internal circuitry and prevent it from working. Always wrap up the AC cord tightly when traveling, and avoid any contact with other metallic devices, like coins, pens or paperclips. These could accidentally short-circuit the adapter by causing an connection of the positive an negative terminals, for example, when bouncing around in a bag.

Laptop accessories for your trip

2010-01-27T19:28:00.000-08:00

This section will help you to prepare for your next trip abroad with your laptop accessories - everything you may need from finding a roaming internet access provider to guarding against computer theft while on the road.

Before you begin your road trip, there are a number of issues you need to address.

Toshiba Tecra 9100 AC Adapter 75W 15V 5A

First, there are hardware issues. You will need the correct laptop power ac adapter so you can plug in your laptop when you get to your destination (and points in between). There are 9 different power plugs in use around the globe. In addition. your laptop may not be prepared to handle the 240VAC power you will encounter in many countries, so you may need a step-down transformer.

Next, you will have to deal with the telephone jacks which do not conform with the standard RJ-11 phone jack we all take for granted while traveling around the U.S. There are 39 different telephone jacks in use worldwide. You must have a telephone adapter to handle each of the phone jacks where you plan to travel. There is also a problem of trying to hook up your laptop computer to a digital phone line – that will blow your modem and then you can not use your computer. A special digital signal tester is available to test the line to make certain you are trying to connect to a phone line that will handle analog signals you computer’s modem can handle.

Then there are the software issues. Laptops manufactured for use in the US have modems installed that do not recognize the dial tones used by most other countries. You will have to learn how to set your modem commands so your computer will ignore the strange dial tones and allow you to dial manually. Otherwise, your computer will not be able to function with your modem trying to recognize the strange dial tones.

Then there is a phenomenon called “tax impulsing”. This is a condition that exists in certain European countries phone systems to measure the amount of time you are on the phone. It is a regular “beep” on the phone line – we normally ignore it during voice calls – that will cause your laptop to disconnect. There is a tax impulse filter so you can have normal communication using your laptop.

High quality and cheap laptop batteries from China

2010-01-26T23:30:00.000-08:00

As we know China has become a place to watch for all things savvy.So many laptop batteries are made in china .such as HP laptop batteries.It easily qualifies as the country that is upfront in the manufacturing of all electrical devices of all kinds. Engineers in the country make a good percentage of the working population and this leads to the main economy driver and major exports being electronics. And their expertise is not limited to making of whole electronic devices but also replacement parts.

Dell Inspiron B130 Battery 6 cells 4400MAH

One of the maintenance parts that require replacing after extended use is the laptop batteries.Laptops being mobile computers feed on a lot of power and unless one of the main reasons for making a laptop is to provide extended use on the road, then battery life dwindles in an hour or two. With time the batteries wear out and they need to be replaced.

Manufacturers know this all too well and they usually tag high prices on HP laptop batteries and IBM laptop batteries since they know they are definitely going to get a market for them.

China is a technology hub and things like Dell or Acer laptop batteries retail for cheaper prices. These batteries can be sold in bulk or individually and needless to say, better prices are always scored when purchases are made in bulk. At this point another idea springs up. Why not sell cheap high quality replacement laptop batteries from China.

They say a business idea is only as successful and fruitful as you believe it to be. When you decide to sell u4873 battery there is the potential of making a good lumpsum in the end. Most people prefer laptops to desktop PC’s due to the mobility factor. And that means that there will always be a market for laptop replacement batteries now and in the future. A good percentage of people are unwilling to make the purchases from the manufacturer due to the high prices. It gets worse when the batteries are sold through a retailer since the price goes up another notch. All these people would be your potential customers and you would actually get to profit from the venture.

To guarantee the chances of you being successful, you need to make sure that you get the replacement laptop batteries from a reliable source. Despite the fact that you are buying cheap ones that does not mean that you should compromise on the quality that you go for. Quality really matters if you want to build a customer base. Go for referrals and read reviews of the best cheap high quality replacement laptop batteries wholesalers so you can choose and ultimately buy from the best.

Most importantly, it is essential to carry HP 0950-3634 adapter when you plan your business trips. Whether you’re looking for a replacement HP ac adapter, a spare, or an extra one for home or office use, this article will guide you in making your decision.
laptop ac adapter is used for providing low-voltage DC power to laptops via a DC jack. They convert the voltage to match the voltage requirements that allow your laptop to function. The HP 0950-3634 adapter allow you to continue your work without any interruption in the absence of a rechargeable battery.
You should be very cautious when you buy laptop ac adapter for your laptop. If you try to power your laptop using an inappropriate HP 0950-3634 adapter it will damage your laptop. There are three primary factors you need to consider before buying an HP AC adapter; namely voltage, tip polarity and tip size.
Voltage
The voltage output from the HP 0950-3634 adapter provides DC to power your laptop. If the voltage does not match the input current requirement of your laptop your laptop will not function properly. Both high and low voltage will affect the performance of your laptop.
Polarity
A power tip will normally have an inner and an outer conductor. The inner conductor may have positive or negative polarity. Based on the polarity you will need to carefully select a HP 417220-001 AC Adapter. If the positive and negative polarity is connected in the wrong way it will cause severe damage to your laptop. Most of the laptop AC adapters have standardized polarity symbols labeled on them, which helps you to buy the right adapter.
Tip Size
The size of the tip is always mentioned in the user manual that comes with your laptop. If the tip size of the HP AC adapter doesn’t match with your laptop, then it cannot be used.

May be you may ask those questions: How to disassemble a laptop keyboard? Can I take it apart and clean liquid spill? Is it easy to repair a damaged keyboard?

I’ve been getting these questions many times and today I show how to disassemble a laptop keyboard. You decide if it’s possible and easy or not.

By the way, in one of the previous posts I explain how to fix individual keys on a laptop keyboard.

I’m doing it for fun. I’m working on a damaged keyboard and have no intention to use it in the future.

First of all, you’ll have to remove the laptop keyboard.

For the keyboard disassembly I’ll be using one of my tools shown on the following picture.

STEP 1.

Remove sticky tape securing the keyboard cable to back of the keyboard.

STEP 2.

Part of the keyboard cable is glued to the keyboard. Carefully separate the cable from the keyboard.

STEP 3.

Start peeling off the aluminum protective film

STEP 4.

Remove the protective film.

After the protective film is removed it’s really hard to attach it back to the keyboard because it’s deformed.

STEP 5.

Most laptop keyboards have some kind of plastic separators.

These separators secured on the back of the keyboard.

Plastic pins are melted on the back of the keyboard and retain separators in place.

Push all plastic pins though wholes on the keyboard.

Start removing the separator.

The plastic separator has been removed.

STEP 6.

Now you’ll have to remove all key caps.

Before you start removing key caps, make a picture or xerocopy of the keyboard so you know the order in which keys are attached to the keyboard.

In order to remove the key cap carefully lift it up with your fingers.

Remove the key cap so the hinge underneath stays connected to the keyboard.

Some big keys have a different design.

In addition to the hinge, some big keys (Back space or Space bar for example) might have an additional support bracket.

Remove the key cap with the support bracket. As you see, the key hinge stays connected to the keyboard.

STEP 7.

Some laptop keyboards might have blank covers on the left and right sides from the up arrow key.

Lift up and remove the blank cover.

All keyboard key caps and plastic separators have been removed.

STEP 8.

Now you can start removing key hinges – key lifting mechanisms.

Carefully separate the key hinge from the keyboard.

Each key hinge has two parts – external and internal pieces.

When you remove the hinge, try to keep these parts connected to each other the same way they are connected on the keyboard.

If the external and internal pieces got separated, you can assemble them together.

On the following picture you see the lifting mechanism (hinge) assembled.

As I mentioned at the beginning, I’m taking this keyboard apart just for fun. That’s why I don’t care about removed parts.

If you following this guide to repair the keyboard, I would recommend to keep all hinges in the right order.

STEP 9.

The keyboard has two sheets laying one on the top of another.

Remove the sheet with silicone (or rubber) nipples.

STEP 10.

Remove the second sheet with traces.

Both sheets have been separated from the keyboard base.

STEP 11.

The sheet with traces has two layers and all traces are running between these layers.

STEP 12.

In order to access and repair traces you’ll have to separate to layers from each other.

The keyboard has been disassemble.

As you see it’s not easy to disassemble a laptop keyboard and even harder to put it back together.

Is it worth repairing? Probably not. These days you can find a brand new laptop keyboard very cheap.

If you successefuly fixed your keyboard, please share your experience! Let us know what was wrong and how you repaired the problem.

HP/Compaq Business NoteBook 6715B Battery charging problem

2010-01-22T18:09:00.000-08:00

Today I got HP/Compaq Business NoteBook 6715B Battery for repair with the battery charging problem. It is a new model and we do not have a lot of experience with these laptops. The customer complained that the laptop will not charge the battery when it is plugged into the AC outlet.

HP/Compaq Business NoteBook 6715B Battery 6 cells 4400mAh

The laptop failure symptoms:

The laptop will not turn on when I try to start it from the battery. When the laptop is turned off and plugged into the AC outlet the battery charge LED doesn’t light up. I know that the battery is not charged and the LED should light up when I plug the laptop into the AC outlet. The laptop starts fine when it is plugged. When I move the mouse over the HP Power Icon in the lower right corner, the balloon will pop up and there is a line in there: Battery Remaining: N/A.

The problem repair procedure:

You can easily fix the problem just by updating the BIOS. HP says that the BIOS version should be at least v1.30. So, go to HP/COMPAQ website and click on Downloads. Select your laptop model and find any downloads for the BIOS. In the BIOS change history you will see the description of changes.

After I updated the BIOS, The HP/Compaq Business NoteBook 6715B Battery charging problem disappeared.

How to buy a good laptop?

2010-01-21T18:38:00.000-08:00

Nowadays，more and more people choose to buy laptops.But they have no experience to buy a good laptop. So I would to share some buying a good laptop tips with us.There are a lot of laptop buying guides designed to help an inexperienced user to buy the right laptop. Some of these guides are good, some of them are not. Here is a laptop buying guide I like because it”s written on people’s language and not designed to sell you anything. This guide explains the difference between a budget notebook, a mainstream laptop and a gaming laptop and what you should expect from your laptop.

Here’s another helpful laptop buying guide.

From myself I would like to add some hardware related details you should think of before you buy a laptop

Laptop AC Adapter.

Make sure to check the size of the AC adapter before you buy a laptop. Usually, you do not see the AC adapter before you buy the laptop and open the box at home. You’ll be very surprised to see that your AC adapter is half-size of your computer. I did this mistake when I bought Dell Inspiron 1525, The AC adapter wasn’t designed for a portable computer at all.

Volume Control.

If you like listen music a lot then you have to choose a laptop with some kind of a hardware sound volume control (sound volume buttons or sound volume wheel located on the laptop). I prefer a volume wheel like on most Toshiba laptops. The volume wheel gives you almost instant access to the sound level. If you do not have a hardware control, then the only way to change the sound volume is through the software settings; it takes some time.

Sound System.

This is again for music lovers. Make sure to find a laptop with a good sound system. In my opinion, Harman/Kardon system is one of the best. I have Harman/Kardon speakers on my HP pavilion dv60000us and the sound is awesome. Sound on my Sony Vaio laptop sucks!

Laptop Memory Location.

The system board is one of the most important and most expensive parts of a notebook computer and you will get an advantage if you know what kind of the system board installed into the laptop. Some modern notebooks have memory integrated on the system board and offer only one extra memory slot to expand the memory size in the future. If onboard memory goes bad, you have to replace the entire system board. It’s OK if your laptop is still under warranty, but what if you have to pay cash for the repair? Also you cannot upgrade onboard memory. Other type of system boards do not have onboard memory, instead offer to you two memory slots on the system board. You will have to replace only the memory stick if it goes bad. System board with 2 memory slots usually can accept up to 2 GB of memory (1GB memory stick in each slot). So, if you plat to upgrade your laptop in the future, make sure that your laptop has both memory slots available for upgrade. Ask a sales person for details.

USB Port Location.

Check how USB ports are located on the laptop. If you plan to use USB devices like a wireless mouse, a flash drive or an external USB hard drive, then it would be nice to have couple USB ports on the side of your laptop not only on the back. Some laptops do not have USB ports on sides and to connect an USB device you have to turn the laptop.

Make sure that USB ports are not located too close to each other. Some older USB devices are big and when you plug it into one USB port, the second USB port becomes unusable.

Keyboard.

If you are a network administrator or have a job related to networking, then probably you use Windows run box a lot. To access the run box in Windows you use a shortcut (Windowd Key + R button). On some keyboards the Windows Key is located in the lower left corner, so you can use one hand to start it. On some keyboards the Windows Key is located in the upper right corner and to start the run box you have to use both hands. Choose the right keyboard for you. For some people it’s not a problem at all, but what if you use this shortcut hundreds times a day?

Parallel Port.

Very often this option is overlooked. If you plan to connect a printer to your laptop via a parallel port then you have to find a laptop with this option. Many modern laptops are designed for modern USB printers and they do not have the parallel port at all.

Laptop Warranty.

If you think that notebook computers do not fail or they fail only during the first year of exploitation, think again. In my opinion, an extended 3or 4 years warranty is a must for any notebook computer. For example I’ll give you approximate prices for some Toshiba Satellite A75 laptop parts if you decide to repair it in Toshiba Repair Center.

System board – from $400

LCD screen – from $550

Pentium CPU – from$300

CPU cooling fan – from $80

Keyboard- from $70

Do not forget to add labor charges -� from $60/hour

Laptop hardware is very specific such as hp dv8000 battery and you can just buy it in any computer store or online shop udtek.com

After you reading this article,may be it’s will give you a good suggestion.

how to troubleshoot a dead laptop and find the problem

2010-01-20T18:59:00.000-08:00

We may offen face the same problem :when our laptop is dead. In this post I’ll explain how to troubleshoot a dead laptop and find the problem. The following troubleshooting tips are not model and brand specific, they should work for most laptops.

Let’s take a look at two different scenarios.

Example 1. The laptop is absolutely dead.
When you plug in the power adapter and press on the power button, there is no signs of life at all. The laptop will not make usual noises, LED will not light up, the fan will not spin, the screen is blank and black, etc… In short, the laptop is dead.

What you can do in this case?
1. Make sure the wall outlet is working and the laptop DC adapter is getting power from the outlet. Try another wall outlet.
2. Test the laptop DC power adapter, make sure the voltage output is correct. You can test the DC power adapter with a voltmeter.
3. Let’s say the DC adapter is fine and the adapter outputs correct voltage. In this case unplug the power adapter from the laptop, remove the battery, wait for 1-2 minutes, plug in the adapter and try turning on the laptop again.

OK, you tested the adapter and it’s bad. If you decide to replace the original DC adapter with a generic one, you’ll have to follow this rule:
The voltage output on your new adapter has to be exactly the same as on the original adapter. The amperage on the new adapter could be the same or higher.

If nothing helps and the laptop is still dead, apparently the motherboard is fried or there is a problem with the DC power jack. It’s possible the DC power jack is broken and the motherboard is not getting any power from the adapter. In this case you’ll have to disassemble the laptop and replace the power jack. Check out this guide for fixing laptop power jack.

Example 2. When you plug the DC power adapter and press on the power button, the laptop starts making normal noises, the LEDs work properly but noting appears on the screen. The laptop will not start.

First of all, take a closer look at the LCD screen. Look at the screen under bright light. It’s possible that the image is still on the screen but it’s very faint. If that’s the case, check out these tips for troubleshooting laptop with backlight failure.

If there is no image on the laptop LCD screen, test the laptop with an external monitor. Connect an external monitor to the VGA port on your laptop and turn the laptop on. You can toggle video output between the internal LCD screen and external monitor by pressing Fn and F4 keys simultaneously on HP laptops, Fn and F5 keys on Toshiba laptops, Fn and F7 keys on IBM laptops. Other laptops may use different key combinations.

Let’s say the external monitor works fine but the internal LCD screen has no image at all. If that’s the case, your problem could be related to the LCD screen or the video cable. Also, make sure the video cable makes good connection with the motherboard and the LCD screen. Try reconnecting, reseating the cable.

In my case, both internal and external monitors were absolutely dead. Neither of them had image. That means the problem is not related to the LCD screen or the video cable. From my experience I know that this problem could be related to the laptop memory.

Try reseating the memory module, maybe it’s not making good connection with the memory slot. Try cleaning contacts on the memory module with pen eraser. Try moving the memory module into another slot. Try replacing the memory module with another known good module, it’s possible that your original module is dead.
If you have two memory modules installed you can try removing them one by one, it’s possible that one of the modules is bad. Try installing different memory modules into different memory slots.

In my case reseating, swapping the memory module didn’t help. I was pretty confident that my problem is not memory related and I moved on.

Try removing battery, hard drive and DVD drive and turning on the laptop without these components.

Also, try turning on the laptop with an external monitor when the video cable is unplugged from the motherboard. If the laptop start with video on the external monitor, apparently there is something wrong with the laptop display panel.

In my case removing the hard drive and DVD drive didn’t help. Unplugging the video cable didn’t help either.
I continued taking my laptop apart piece by piece and tested it after each step.
I removed wireless card, modem, disconnected the keyboard but it didn’t help.

I still wasn’t able to boot the laptop with video on the external monitor.

Finally, I disassembled the laptop and removed the motherboard.

On this picture you see my final test. The motherboard has been removed from the base and I assembled basic barebone system on my bench.
1. Motherboard. Like on most laptops, in my case the video card is integrated into the motherboard
2. CPU with heatsink and cooling fan.
3. Known good memory module.
4. The power button board witch I need to turn on the system.
5. Working DC power adapter.

Still cannot get any video on the external monitor. The system turns on, the cooling fan starts spinning but there is no video.

At this point I’m 95% sure that the motherboard is dead. CPU failures are not very common, so it must be bad motherboard. may be this arcitle is good for you.thank you for reading.

How to good use Dell E1505 adapter by yourself

2010-01-19T18:25:00.000-08:00

The Dell E1505 AC adapter

Dell Inspiron E1505 AC Adapter 90W 19.5V 4.62A Description:
Input: AC100-240V (worldwide use)
Output: DC19.5V 4.62A
Power: 90W
Connecter size:
Internal Diameter: 5.0mm
External Diameter: 7.4mm
With central pin inside

This part, like the batteries, is an essential element of your machine and is also the cause of a great number of breakdowns. Indeed, one of the elements most fragile of your laptop is the AC connector, i.e. the connector female in which comes to plug in the plug of your Dell E1505 AC adapter.

The repetition of these plug in and sometimes their useless violence ends regularly up tearing off the female connector of the motherboard.

That often occurs by stage, initially light poor contact, then as you move the cable in all the directions to find the current, the connector is torn off definitively, or the produced sparks roast the motherboard.

An adapter in bad condition (stripped cable, broken case repaired with tape…) is often the cause of a fatal electric problem to the motherboard of your laptop. To avoid that you just have to purchase a new AC adapter (genuine), it is always less expensive than a repair or a swapping of the motherboard.

About the compatible Dell E1505 adapter

To try to save some dollars (whereas often the genuine adapters are not much more expensive) or simply because their retailer does not propose a genuine adapter, much buy “compatible” adapters.

Let me be frank, for repairers these adapters are a blessing! Their male connector, relatively adapted to the socket of the laptop, tears off more often than others the females connectors.

Their voltage and their amperage more or less close to the needs for your laptops and a sometimes irregular flow, even straightforwardly random, and their annoying tendency “to kill the fuses” by at the same time roasting your motherboard and other power cards, are an important source of occupation for the technicians.

The failure rate, properly incredible, due, in an unquestionable or probable way, with these adapters makes that I dis-advise them formally. I am the first to propose to use compatible parts when they are less expensive and as powerful as the original parts. But for the AC adapters I advise prudence

We must have accessories for laptops

2010-01-18T22:58:00.000-08:00

Laptop accessories are additional items that can be used to enhance the performance of a laptop computer, improve user experience, or assist in the protection of the laptop.

A laptop is a computer that has a built-in keyboard and a folding screen. Laptops vary widely in size, thickness, and weight and provide computer users the ability to work in a wide range of locations.

Most of the time people wouldn’t give much importance to these kind of accessories (such as laptop battery ,laptop replacement keyboard,laptop ac adapter,laptop car charger,laptop universal power) as they gave for the main things. In our case the customers will give less importance for the laptop accessories when compared to a new laptop before buying it. But the thing is the laptop case is going to protect the main thing i mean the laptop. Like that only all the accessories have their own roles protecting their main things or primary things. In this article I have shared some basic ideas on choosing a laptop case .A lot of companies out there giving false information for people regarding their products. So the wise thing is we should snag information’s regarding a product before going to buy one.http://www.udtek.com/laptop-battery-c-1.html

The desktop ages are over, and now everywhere laptops have become a part of people in everyday life. The laptop has turned into a must have product while going for offices or while going for some business trips. While going for buying a laptop mostly people will ignore important things to be considered. This happens because they are ready to spend a lot of money for the laptops, but when it comes to accessories they are satisfied with the freebies given with these big things. That’s the reason most of the companies are giving their customers a laptop cases with their products, But Giants like Sony and Dell don’t have any free option like those, because they don’t want to give their customers some cheap laptop cases as a free thing. Regular cases, which are given with the laptops are soft and they are used for only common accidents not for the hard bumps or drops or water. Below are the some of the important guidelines you should have a look while going for a new laptop case.

The first and the foremost thing you should consider should be the waterproof property of the laptop because the most often the laptops are affected by water only. So its wise to test the laptop case there itself in the store before making the purchase. And the next thing you should consider is the chemical resistant proof on the top of the case. Most of the leather cases will come with this option only. The third thing you should have a serious look is the space inside the bag. If it is used only for carrying a laptop then you can go for ordinary ones, but if you need to put something else like mobile phones or chargers for the laptops. These are the important things you have to take a look before making a buy. I could confirm that the knowledge presented above can give you a real advantage.

The way to use the cheap laptop battery as an expensive one

2010-01-18T18:56:00.000-08:00

What happens when you buy a cheap battery that quickly loses its kick? You don’t want to have to go out and buy another battery, then you will have spent more than it would have cost to get a good one originally. Or maybe you already have a really good laptop battery and you just want to keep it running at its peak performance, to prevent a future purchase. Either way you need to know the secrets to extending the life of that laptop battery such as Original HP Pavilion dv8000 Battery 8 cells 4400mAh, and I am going to share them with you.

http://www.udtek.com/original-hp-pavilion-dv8000-battery-cells-4400mah-p-30282.html

So what exactly can happen if you don’t take care of that cheap laptop battery?

just follow the simple tips .

Don’t allow your laptop battery to discharge completely. Allowing a battery to completely discharge can have very negative effects on the overall performance and life of the battery. Often times we find that by draining the battery can in some cases cause complete battery failure or drastically shorten the charge capacity of the battery. What this means in plain English is your battery will die and/or not hold as much of a charge therefor draining quicker than it should.

Many manufacturers recommend that your battery is stored and maintained at around half or 40% charge to maintain optimal performance. Always read the user manual that came with your laptop, or if it is a replacement battery read the included documentation.

Add more memory or RAM to your laptop. Many people would speculate that this method will not help to save battery performance due to the fact that more memory requires more power to maintain. While this reasoning is true in part, if your laptop is short on RAM, your hard drive will be constantly running to make up the difference, via your swapping file, which in turn would use a lot more power and battery life. If you are using a laptop that has say 512mb of RAM, increasing this to 1gb should be more than enough to maintain optimal performance.

Turn off your Wifi while not in use. There is usually a switch to turn off your Wifi, however you may need to turn it off in the Wifi configuration panel. Your Wifi uses a lot of power when it is not connected because it is constantly searching for a connection, so it is a good idea to make sure it is turned off when not in use.

Remove your battery while running your laptop on AC. If you are working from home and your laptop is plugged in to the AC, removing your battery is a good habit to have. Keep in mind that you do not want to store your battery completely discharged, but this method will allow your laptop battery to take a break while not in use.

Take care of your battery and keep it clean. I should probably say this twice, but I won’t. Taking care of your laptop battery is crucial to its performance. Over time the metal contacts on the battery will build up gunk that can cause the battery to work harder than it should in its daily operation. So once a month, pull out the battery and wipe it down with a cloth, clean off the contacts and you will extend its life.

Lower your graphics use. You can save a lot of power consumption by dimming your screen, lowering the screen resolution and removing the fancy graphics. Windows especially uses a lot of graphics on the menu’s and such, which is easily turned off and cut out a lot of the battery drain. The overall look may not be as pretty, but were going for battery life here.

Remove USB devices when not in use. Usb devices often require a good amount of power to continue running. If you are not using them make sure to remove them from the computer and this will help to save on battery consumption.

Defragment your hard drive regularly. Defragmenting your hard drive can help it to run more efficiently and require less power consumption. The more efficiently your hard drive operates the less work it will require to maintain operation. So keeping this in order and defragmenting regularly will benefit the life of your laptops battery.

Keep your laptops air vents clean. Laptops, or computers in general operate more efficiently when running at cooler temperatures. This is also why you see high end computers with water cooling systems. Anyways, by keeping the air vents clean you allow more air flow for the fans to run and the laptop will remain considerably cooler.

Optimal laptop performance causes optimal battery performance. Over all, the better your laptop performs the longer your laptop battery will last. It is very disruptive to your day when your laptop battery dies and you are constantly looking for a good place to plug in. So use the tips above to maintain your laptops battery at peak performance and life on the go should be a little easier.

Set your laptop to hibernate rather than stand-by mode while sitting idle. While stand-by mode is great for saving on power consumption, setting your laptop to hibernate will allow the computer to completely shut itself down and still save your laptops state where you left off. Both options are good, you should at least be doing one of them, but hibernation will be the most effective.

How many Cycles of Charge can HP dv6000 Laptop Battery go through?

2010-01-12T18:54:00.000-08:00

In our life we always ask How many Cycles of Charge can a Standard Laptop Battery go through? and now i will give you my answer for reference.

http://www.udtek.com/hp-pavilion-dv8000-ac-adapter-90w-185v-49a-p-2946.html

Regular lithium ion batteries that power laptops can be recharged 300-500 times before you notice a drop in charge retention.Reconditioning can help you extend the laptop’s battery(hp dv8000 battery) life as long as the battery itself is not completely dead. It needs to hold at least 45-60min of charge to be considered suitable to recondition.

Like car batteries, laptop batteries can be recharged up to 500 cycles. Once the cycle of 300-500 charges is done (in about 2-3 years), you will notice your a steady decline in your battery’s charge retaining capacity.If you don’t want to junk it yet, reconditioning is the answer to revive and reuse an old laptop battery such as my hp pavilion dv6000 battery. So how do you figure out if your own battery can be reconditioned?

Simple! Just see how long it runs on a full charge when you put on you laptop ac adapter. If the time till complete discharge is about 1 hour, the battery can be reconditioned.But if you notice the battery discharging in just a few minutes, then it needs to be replaced.

The capacity of notebook batteries

2010-01-11T19:01:00.000-08:00

Notebook batteries consist of individual cells,such as a 6-cell battery.
Is there any way to estimate the overall capacity of a notebook battery from the number of its cells? How much capacity does such a cell typically have?

When selecting a notebook battery,such as hp pavilion dv6000 battery HP/Compaq Pavilion DV6000 Battery 12-cells 8800MAH Description:
Cell Type: Li-ion, 12-cells
Voltage: 10.8V
Capacity: 8800MAH
UL certificated cells inside!

http://www.udtek.com/hpcompaq-pavilion-dv6000-battery-12cells-8800mah-p-20875.html

manufacturers will often list an amount of “cells,” where each cell has a certain capacity; thus a 9 cell has 50% more capacity than an equal model 6-cell battery. That is useful for comparing directly, but the story is more complex if you wanted to compare different batteries on different laptops. Batteries have a voltage rating (V) and milli-Amp hours (mAH), which, if multiplied together, give you milliwatt hours.

For example, a 14.8 V battery with 4460 mAH gives you 66,000 milliwatt hours (66 watt-hours). You can compare laptop batteries this way, but also keep in mind that different laptops have very different power requirements that vary based on the components and how well the operating system manages power consumption. Typically, bigger, heavier batteries will give you a higher watt-hour rating. A 6-cell battery may be the same form factor as a 9-cell, but the 6-cell will weigh less since there’s less chemical in it to hold onto that charge.

If you are a mobile warrior, you will want the most cells and/or most watt-hours you can get into your model so you can go 5 or 6 hours without a recharge. It is so painful to run out of power before you are ready. ” And here I suggest you a online-shop to buy good notebook batteries.My friends have bought from udtek.com .There are many computers hardwares on udtek.com. She thought it’s a good service , fast shipping shop,and high quality shop.May be it’s good idea for us to see what products we need .
