Keyboard

Laptop notebook keyboard

In laptops, a keyboard is the main input device. It’s interface between a user and a laptop.

In most laptops the keyboard is connected directly to the motherboard via a flat ribbon cable.

KEYBOARD REMOVAL STEPS.

In most laptops you can remove the keyboard as it explained in the following three steps.

STEP 1.

Remove keyboard bezel.

Remove keyboard bezel

STEP 2.

Unscrew the keyboard from the laptop base. Usually there is one or more screws securing the keyboard.

Unscrew keyboard from motherboard

STEP 3.

Disconnect the keyboard cable from the motherboard and remove the keyboard.

KEYBOARD RELATED PROBLEMS.

1. Here’s a very common “keyboard related problem”.  When you press on keys U, I, O, J, K, L, M the keyboard types 4, 5, 6, 1, 2, 3, 0. It happens because the “Number Lock” function is enabled. You can turn this function off via a shortcut on the keyboard. Hold down the Fn key and at the same time press once on the NumLk key.

2. One or more keyboard keys came off. You can install these keys back on the keyboard, you’ll find lots of instructions on the internet or YouTube how to do that.

3. When you press on one key it types two letters. For example, you press on W but it types WE, you press on T and it types TY, etc… Most likely this problem is related to the keyboard and it has to be replaced.

4. Some keys in horizontal or diagonal row stopped working at all. Again, most likely there is a problem with the keyboard and it has to be replaced.

ATTENTION! If you still have the same issue after replacing the keyboard, there could be a problem with the keyboard controller on the motherboard. It means the whole motherboard has to be replaced.

A laptop keyboard is not repairable. If it stopped working, you have to replace the whole unit.

    Please let me know if you have the part or where I can find it.

    Here’s what you can try:
    1. Insert keyboard cable into connector on the motherboard.
    2. Place the locking tab in place.
    3. Secure everything with sticky tape.

    DAVID,

    pls if a keyboard key is stiff,4 example letter G is stiff what can i do ? on less u press it by force.

    Probably something got stuck under the key.
    1. Blow off the keyboard with air compressor (or canned air). This will removed dirt/dust collected under the keys.
    2. If it doesn’t help. You can carefully remove the key cap and clean it up. After that install the key cap back on the keyboard.

    Keith Collin,

    How do you turn off the touch pad mouse at the bottom of the keyboard, my wife uses her laptop as her work comp. but prefers a wireless mouse. She is constantly having problems with fingers or wrists sliding across it and messing things up.thx.kc

    Depends on the model of your laptop. For example, on Toshiba laptops you use Fn+F9 keyboard shortcut to enable/disable the touchpad.

    My cat tore off 3 of my Toshiba laptop keys, and I don’t have money to fix it because I’m only 13. So, is there any way I can fix it? The keys still work when I press on them its just really hard to type normally, right now I am on my mom’s old win xp computer to send this. Mine is a Win 7 and I got it for Christmas in 2009, I’d like a reply back if there is any way to fix my keys, I don’t think they snap back on like other keyboards…

    nella61,

    I just wanna ask if one of the key doesn’t work, do I need to replace the keyboard ?one of my key just stop functioning all of sudden.

    If one of the keyboard keys stopped working completely, but all other keys work properly, you’ll have to replace the keyboard.

    TD,

    Is there a different name for the mouse pad (controller) below the keyboard? I am trying to fins a cover for it or turn it off. I am constantly hitting it with my hands and moving my cursor to different spots while typing.

    It’s called touch pad. You should be able to disable the touch pad in the control panel.
    Go to Control Panel >> Mouse and search in there.
    If you have a Toshiba laptop you can hold down the Fn key and at the same time press once on the F9 key. This combination will enable or disable the touch pad.

    Update:
    It happened again this morning and I tried the fn and number key trick and it worked. Now, why do you suppose it makes it number lock on its own? Is that something I should be worried about and fix? Wow, I’m so grateful, thankyou thankyou thankyou! I thought I was going to have to ger another computer!

    Well, I spilled some water on my laptop and my keyboard wouldn’t work after that, like when I pressed one letter two would come up, my computer beeped on startup. So I ordered a brand new internal keyboard from amazon and my friend put it in for me. So, sometimes it works just fine, and then other times it doesn’t. For example, the p is an asterisk, then the letters are numbers as described above in common keyboard related issues. What is going on? How come it works sometimes, (like right now) and other times it doesn’t? Also, I have restarted it, turned it off and rebooted it, like 8 times and still had the same issue. It’s like it works when it wants too. Do you have any thoughts, repair man? thank you so much!

    William,

    Many of the letters of the keyboard pads are worn off & need replaced. Where can I find the just the pads as the keyboards work just fine otherwise?

    You can buy individual pads on eBay but they are about $3-7 each. If you have a lot of keys worn off it makes sense to replace the whole keyboard which you can buy for about $20 on ebay.
    If you don’t know how to replace the keyboard, you can purchase a new keyboard, remove keys you need and install them on the old keyboard.
