The keyboard works in BIOS, but does not work in Windows 7, after spilling tea (without sugar), how to fix it?

Question

Do it yourself

The touchpad turned off immediately, the keyboard worked/didn't work as desired. I thought the problem was in the keyboard, put a new one: nothing has changed. But in BIOS everything, oddly enough, works fine.

Answer 1

Try disconnecting the loop of the non-working touchpad, if it is short, then it can bug the system. Another reason may be a flooded keyboard socket on the laptop board.

Answer 2

Maybe the harness is not fastened properly? I took off the keyboard 4 times and played until I installed it normally. not all keys worked.
