so i have a Gateway MS2300 and it won't power on at all.

AC Adapter is OK

Capacitor Discharge by disconnect power sources and press and hold power key for long tested and nothing changed

i opened it and im going to check the voltage by multimeter.

we have voltage after charge socket.

we have 19v voltage on capacitors.

also have voltage on battery charge connector (1,2 GND) (3 4 5 are 3.2V) (6 GND) (7 8 are 19.2V)

power key (the micro switch) is ok (tested with buzzer test on multimeter)

what else i should check for this kind of problem?

thanks regard

Amir
