No power. Disk not spinning. Charging led won't turn on. Tried with and without battery.
Motherboard is abq52-la-c811p. 19.5 v on the power jack red wires, 0.7 on brown and 0 on all the others.
0v on PQB1 and PQB2 and 0 on PRB1. I think it is a short to ground, but cannot test further on live voltage as the motherboard has started to spark around the capacitors near the mosfets above.
I need to replace the mosfets, caps and resistors near tehm too as I fear they are damaged from the sparking, but where else should I test to find the short? Does anyone understand the power architecture and can they explain it to me?
Attached is schematic of motherboard.
