Hello friends,
I have this laptop AMD Platform starting & not posting, fan spinning.
When i press power button, the board get almost immediatly 0.5A ~ and board get stuck at 0.5A with power button led blinking indefinitly.
If i stop the computer (pressing 5s power button), board stop and when i restart i get approx 0.37A ~ and
I try to reflash the bios with no luck, same result, and i try disabling onboard ram (i remove resistors accordling schematic), no more progress.
CPU and his area heat, maybe the cpu is dead?
I look for some signal:
SLP_s3 => 3.28V
ALW_PWRGD => 3.3V
PLT_RST_N => 0V
Of course i get no display (internal or external), no caps lock indicator.
What can i look for ? is it dead?
