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.

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.

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 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

Buy a second Dell Inspiron E1505 AC Adapter for your holidays

Stop lugging your Dell Inspiron E1505 laptop AC adapter back and forth between home and office. Get a second Dell Inspiron E1505 laptop AC adapter for your laptop and keep one in the office and one for home or travel.
