Problem description
#incomplete
Symptoms
- Green light on charger not turning on
Solution
This problem has multiple causes:
- ADAPTER_SENSE not 3 V due to bad DC in board. 16–20 V on ADAPTER_SENSE means charger voltage is leaking into ADAPTER_SENSE, below 2 V means it is missing usually due to a bad DC In board.
- PP3V42_G3H missing
- SMC not working(if SMC is off, you will have 12.23 V on PPBUS_G3H instead of 12.56 V) because it is dead, not turning on(SMC_RESET_L low).
- Corrosion of the SMC's solder connections
- Keyboard bad, shorting PP3V42_G3H to ground or power button stuck on.
- Bad U7000
- Bad U7001
- Bad U7100 — indicators: PPBUS_G3H Below 4 V, board taking 40 mA, U7100 getting warm (check via thermal camera)
