Hello guys,
Got my hands on this laptop and started troubleshooting. The only thing I know is it turned off and never came on. No lights and not coming on.
Started doing some checks and found the main rail present everywhere. Something weird though as the gate of the first input mosfet is 3.7V and the output is 20.3V.
Tried to trace the gate and it looks like it's connected to pin 61 on the io. Is the IO supposed to monitor the gate voltage?
5V and 3.3V are missing from the coils. Found by lifting PL6202(on the 5V rail) the clicking fet sound goes...
