Hello,
I have an issue with an 820-3115-B board. Board was liquid damaged - put it through the ultrasonic cleaner and powered it up - green light and fan spinning. Great! Disconnected magsafe and went to have something to eat. Came back 10 minutes later will not power on: gets green light but will not power on at all. I have the following readings:
PPBUS_G3H: 12.62V
PP3V42_G3H: 3.497
PPVRTC_G3H: 3.337
PP5V_S5: 5.01V
PP3V3_S5: 3.3V
PP5V_S3: 0V
PP3V3_S3: 0V
PM_SLP_S4_L: 0V
Got a weird issue where I get a short to ground on PP5V_S3 when the machine is plugged in but the short goes away after you leave the magsafe unplugged for a while?
Any help would be appreciated with where to check next. Thanks
