My HP 239427-001 Adapter is not Working for me

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.

Tips to Maximise Dell Inspiron B130 Battery Life

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.

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.

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.

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.

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.

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.
