Hi,

I've got this laptop for parts, no historical. When I try to power on, blue led lights up for 1s and stop, with or without battery. Battery is charging good - orange led is lit.
I've checked ALW voltage, 5v is here, but 3v is missing and I found a short on +3VS.
I've isolated this rail, and injected 1v/1a and found a heating resistor behind the CPU (on the other side), on boardview, it's connected to +3VS on one side, and +3VS_APU on other side.
I've removed it, no more short on +3VS, but +3VS_APU is still shorted (3Ω to the ground) and only other pins are under...
