820-4924 that had no power and no light on the MagSafe.
Replaced Q7180 and U7100. Magsafe LED now works but PPBUS_G3H is only 1V.
Same after Q7130 was replaced.
Power draw on PSU is 0.017 amps.
History unknown, no liquid damage spotted.
The schematic I have is password protected so can't copy/paste/search which makes tracking this hard. I am looking around page 54 (PBus Supply & Battery Charger) but am going in circles.
Any advice appreciated.
