Hi everyone, I'm stumped here.
Liquid damage around U7330 and battery connector. Replaced corroded capacitors around U7330, got the board to power on then will not enter S4. Then noticed area between Q7155 and battery connector very hot. PPVBAT_G3H_CONN shorted to ground. Removed Q7155, no change.
Rails are
PPBUS_G3H 12.55V
PP3V42_G3H 3.42V
PPVIN_S5_HS_COMPUTING_ISNS 12.55v
PPVIN_S5_HS_OTHER3V3_ISNS 12.56v
