Hello!, have a board which is 820-4924-A and was after liquid damage. After cleaning and replacing corroded components board turns on, boots, but won't detect battery and fan at all. So far what I managed to measure:
PP3V42 - 3.42v
PPBUS-G3H with connected only battery is 11.04v
PPBUS-G3H on charger 12.25v
Resistor R5380 - 2.0K
Resistor R5381 - 2.0K
Resistor R5492 is only 148K which should be 200K
SMC_RESET_L - 3.37v
PP5V_S3 5.15v
Battery connector under the board was badly corroded (photo before) so can it be that SMC chip needs replacement due to short? Sorry, still pretty unexperienced, hungry for new info, thank you!
