Bit shooting in the dark here without schematic and boardview.
I can detect shorts in the PPBUS_AON fuses.
I pushed 2V through the shorted PPBUS_AON line but did not pull any current. Perhaps too low voltage to trigger any short. Anything to consider before I ramp up the injected voltage to detect a short location?
Also, shall I UC the board as it is very sticky after the energy drink spillage and seems heavy oxidation around the SSD, audio amplifier chips in particular?
Lift up the F5200/01 fuses, and it seems short is on the PPBUS_AON side.
PP3V8_AON - 0.156
PP5v_S2_MAIN - 0.397
PP1v8_S1_CLVR_VDDH - 0.101
Not sure what area to concentrate on first.
