Problems with Laptop Keyboard



Keyboard is not working

There are a few things to try:
Make sure your keyboard is plugged in to your computer correctly. If your keyboard connects to a
USB port, try unplugging the keyboard and plugging it into a different USB port.
A typical USB cable and port
Many wireless keyboards require special drivers to work properly. Be sure that you have installed any software that came with the keyboard. If you use a wireless Bluetooth enabled device for your keyboard, see Set up a Bluetooth enabled device.

Try plugging your keyboard into another computer. If it still doesn't work, it might be broken.
Consider replacing it with a new keyboard, or, if the warranty for the keyboard is still valid, exchanging it for a new one with the manufacturer.


Windows doesn't recognize keyboard or some key.

The driver for your keyboard might be missing or need to be updated. If your keyboard came with a software disc, insert it into your computer to reinstall the driver. Otherwise, follow these steps to update your driver.
1.  Open  Keyboard  by  clicking  the Start button   ,  clicking Control  Panel,  clickingHardware  and
Sound, and then clicking Keyboard.
2.  Click the Hardware tab, find the keyboard you're using, and then double-click it.
3.  Click the Driver tab, click Update Driver, and then follow the instructions.
4.  If you are prompted to restart your computer, do so.
Some keys stick or don't depress properly.

Turn your keyboard upside down and gently shake it. This will help remove any accumulated debris that might be preventing the keys from functioning properly.

You might also want to use compressed air to clean out dust from hard-to-reach areas under the keys.

How to remove keyboard?

1 Enusre the laptop is fully powered off, unplugged from the wall, and the battery taken out.

2 Turn the laptop over. On some models icons indicating which screws are attached to the keyboard are displayed. If not, you may have to "eyeball" it if you can't find a breakdown for your model online.

3 Remove those screws with a T-8 or Phillips screwdriver.

4 Turn the laptop back over and open it up. Check and see if the keyboard is tucked under any plastic pieces. If so, find if those plastic pieces are screwed into anything, and unfasten them as well. If not, it probably uses clamps that can easily be removed.

5 Remove the plastic pieces carefully with a toothpick or plastic pick if there is any in the way.

6 Unscrew any screws at the top (if necessary) and remove the keyboard itself from top to bottom. You'll notice that the keyboard is connected with a thin, but wide, data cable to the system board at the bottom.

7 Take that same pick and lift the plastic connectors that hold in this data cable in place.

8 Carefully remove the data cable. Now the whole keyboard should be free.


Replacing keyboard

These instructions will help you to remove and replace keyboards on various laptops. I will not be able to cover all models but you’ll get the idea. Steps for removing and replacing the keyboard are similar for most laptops.
If your keyboard is missing a key, it’s not necessary to replace the whole keyboard.

Warning!

- if your laptop is still covered by the manufacturer’s warranty, do not open the case or you can loose the warranty.

-  always  remove  the  battery  and  unplug  the  AC  adapter  before  you  open  the  laptop  case.

- if you damage the keyboard connector on the motherboard you’ll have to replace the whole motherboard.

- proceed on your own risk.
