Hi I have one of these for repair. Basically what happens is when I hook it up to bench supply Power Led comes on, fan spins then after it shuts down. If you press the power button again as many time it will not power up (PCH COLD). If I remove adapter from socket and re-apply it the laptop will switch on and then off again as before (PCH Very hot) . I have noticed the PCH gets very hot until you press the power button and the fan comes on it gets a bit cooler, and if you press the power button again and it does not switch on as before the PCH stays cold.
The 3.3v and 5v stay ok throught all of this.
Any ideas would be helpful. I have also tried different ram. is it possible CPU or Bios?
