Topic: Hardware experts please help.

Hello house, I just discovered that half of d keys of my laptop have stopped functioning and all was still working well d previous night. PLEASE WHAT CAN I DO? Meaningfull contributions will be appreciated.
Thanks house.

The first thing you have to do is to dust clean the kepboard. Well this may require removing the kepboard.

If after cleaning and the problem still persist, then you will have to take it to nearest Computer Engineering workshop.
