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.

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.
