RMSRST# 0V Your Mob will not power on Bad Sio or Bios but may be you are mising some SO state voltage Rail +10VALW +15VALW +5V VCC1 on pc99

Re: Hp g62-355dx no power

test basic requirements of SIO KB3926
VCC1 pin 9
AVCC pin 67
ECRST pin 37
LID EC pin 127

requirements to SIO good and now check voltage Rail +10VALW +15VALW +5V VCC1 on pc99

PU6 pin 3 is conneted to PC99 it should be +5V
check voltage Rail +10VALW +15VALW also
