How to disassemble keyboard

posted in: Keyboard | 28

In this guide I show how to disassemble a laptop keyboard.

I’m doing it for fun just to see how it’s built. I’m taking apart a damaged one and have no intention to use it in the future.



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

STEP 1.

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

STEP 2.

Carefully unglue the cable from the back.

STEP 3.

Start peeling off the aluminum protective film.

STEP 4.

Remove the protective film.

After the protective film is removed it cannot be reused.

STEP 5.

My keyboard had two plastic separators on the top.

They are secured to the back via pins.

Plastic pins are melted on the back and secure separators in place.

Push all plastic pins though wholes on the keyboard.

Start removing the separator.

The separator has been removed.

STEP 6.

Now you’ll have to remove all key caps.

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.

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 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 body.

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

When you remove the hinge, try to keep the internal part inside the external. Do not separate them.

If they separated, put them back together.

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.

Remove the sheet with silicone (or rubber) plungers.

STEP 10.

Remove the second sheet with traces.

Both sheets have been separated from the base.

STEP 11.

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

STEP 12.

You can separate these layers from each other.

The keyboard has been disassemble.

Can you repair a keyboard? My answer is NO! Keyboards are cheap and not designed to be disassembled.

    Greetings Bonny,
    What had happened is when the power went out, some of your files that were in use did not properly close which usually do during normal shutdown. To solve this, you should boot using your Windows CD or DVD depending on your version. Choose the repair console which will give you an emergency command prompt. It will ask you which Windows install to log into. Choose #1 then press enter. Next it will ask for your Administrator password. If you set one, enter it now and press Enter. If you did not, just leave it blank and press Enter. At the command prompt, type the following:
    chkdsk c: /r
    Assuming your windows is using the C: drive, this will correct any open files as well as check your HD surface for any defects. This should correct your problem and allow you to reboot. If successful, do a disk defrag. Afterwards, you should be OK.
    Hope this helps you. Take care & God Bless….

  3. @ tim bob,

    does anyone know how to disassemble packardbell easynote tx86 laptop

    I’m personally not familiar with this laptop. I looked up some pictures on the internet and I think you’ll have to go though the following procedures in order to disassemble the laptop.
    1. Remove all covers from the bottom and remove RAM, hard drive, DVD drive if possible.
    2. Remove all screws from the bottom of the laptop.
    3. Remove the keyboard.
    4. Remove all screws located under the keyboard and disconnect all cables.
    5. Separate top cover (palm rest assembly) from the base cover.
    This is just a guess.

    Thanks for your answer, I recently got a reply from another forum and it solved my problem when keys start malfunctioning:

    The solution I am told is to Shut down system and take out battery for few minutes. and It really solved my problem.

    However My question still exist what kind of glue is used to place that plastic sheet back on metallic backside of the keyboard.

    Thanks

  6. zee,

    I was recently facing problem with (ASDFJKL: and Enter Keys)all these keys print dual characters and also have problem with my Arrow Keys that are working in wrong direction.

    I have gone through many forums suggesting cleaning and replacing.

    I don’t think that cleaning will help in your case. This sounds like keyboard failure or possible motherboard failure (bad keyboard controller).

    Instead of cleaning the keyboard, I would try replacing it with a new one. New keyboards for HP dv2500 laptops are not expensive.

  7. sorry i forgot I am using DV2500 series and its hp DV2670 model.

    Regards
