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.
STEP 2.
Unscrew the keyboard from the laptop base. Usually there is one or more screws securing the keyboard.
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 using this method.
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.

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