Finding dell precision m20 battery and other laptop parts

A laptop is a more sophisticated machine than a desktop computer, and more expensive too. It can be a nightmarish situation if some parts(such as laptop battery,laptop ac adapter) of the laptop you just bought for so much money get damaged. More so, because the spare parts of laptops are so rarely available and so expensive.

A laptop includes most of the typical components of a desktop computer, including a display, a keyboard(laptop replacement keyboard), a touch pad, and also has a charger. All of these parts, and also the motherboard, the memory, the video cards, the optical drives etc. are vulnerable to damage. Most of these parts are either not available, or are too expensive to be considered. Many of you would instead prefer to buy a new laptop, rather than shell out so much money for.

Here’s a good way to find inexpensive spare parts for your laptop or notebook computer. In most cases laptop parts are not interchangeable (except memory and hard drives) and it’s very important to use a correct part for repair or your computer will not work properly. You should search for spare parts by the part number.

1. Finding part number.
Many websites can help you to find the part number such as hp 239427-001 Adapter . On the website you can search for notebook parts by vendor. You’ll find part numbers for Compaq, HP, IBM, Sony and Toshiba notebooks.
Select your vendor/model line, choose laptop series and choose the laptop model. After that you can search through the entire list of parts for your laptop or just use the filtering tool to find a particular part. Each part usually has an original part number and an alternative part number. You can use either number. Now, when you know the part number, you can start searching for the best price.

2. Fining inexpensive parts.
First of all, try searching on google.such as you want to buy dell precision m20 battery You can find a very inexpensive brand new part. If there are no new parts, you can buy a used one. If you cannot find this part on eBay, try searching by the part number on Google. Most likely the search will bring you many results and you will find what you are looking for.
Finally, when you receive the part, you can use laptop service manuals to install it.

Like every machine, laptop also needs replacement of parts. You can find laptop spares at affordable prices on websites like udtek. com and other websites.

Tips of Hp 239427-001 Adapter

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

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

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.

Do not forget to take HP laptop AC adapter

All these gadgets will become useless if you forgot to pack an laptop AC adapter.If you are a frequent traveler, then surely you have to maintain a list of important things to be packed before the journey. You’ll carry your laptop, camcorder, and other electronic gadgets.

Hp 0950-3634 AC Adapter 60W 19V 3.16A 2-prong

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.

Disassembling laptop keyboard by yourself

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

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?

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

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

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

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

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?

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

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 udtekHP/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 .

For what use is the strip of LED lights on my battery?


Most Dell batteries such as Dell Latitude D600 Battery

Voltage: 11.1V
Capacity: 4400mAh
Type: Li-ion, 6 cells
UL certificated cells inside!
Brand New Replacement Product, works as genuine parts, 100% OEM Compatible!!

have an LED indicator that allows users to see how much run time and how much overall battery life are available at the touch of a button.

To check battery charge, press the button and the number of lights that appear will tell you charge status. If all lights appear, you have a fully charged battery. Each light that appears accounts for approximately 20% charge. http://www.udtek.com/dell-latitude-d600-battery-cells-4400mah-p-24068.html

To check the battery health, press and hold the status button on the battery charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition and approximately more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights appear, approximately less than 60 percent of the charge capacity remains, and you should consider replacing the battery. http://www.udtek.com/dell-latitude-d600-battery-cells-4400mah-p-24068.html
