Question Press one key gets multiple letters appear

[Joshua Rei Cofreros]

Whenever I press a certain key, screen turns off... after using KeyboardTest, it shows that when I press the power button, it triggers multiple keys (vise versa), mainly A,D,J,K,L, ";"and sometimes WinKey, NumLock, 6 and Esc

So I decided to change what the power button does, to nothing... but It gets even more complicated when I found out K,L.D and ";" triggers J as well (happens when I type like this: JD JK JL :J) ... and this thing only started to happen when my laptop updates to the latest version.

I started down grading but the problem still persist... Note that nothing was spilled in my keyboard... please help

How old is this thing and what model ?

Have you considered trying a a factory restore ?
