Re: Hp g6-1350ep

the 4 keys are on the same matrix could be just the keyboard.

Re: Hp g6-1350ep

or maybe a clean of the K/B socket with some isopropyl
and a close inspection of socket for damage also

Problem solved, thank you for help me to solve this, the problem was the trace from KB (MY5) to CN4 (Keyboard Con.)

Now that's a weird one. Did it have a liquid spill by any chance? Anyway, kudos for fixing it.

Yes i think so... it seemed to caught some liquids and have been cleaned and then come to my store because the four keys do not work

It is my opinion.

I`m wondering how did you know that was the problem?
your talking about mV or you find it with the scope?

With the help of shematics i tested all pads with multimeter on test diode from CN4 to keyboard controller, the one that does not have continuity was MY5 that goes to pin 44 of keyboard controller.
