This Mac draws 0.019-0.025 Amps at 16.5V
Green light on charger but no power. Does not respond to SMC reset.
In measuring rails I got to PP5V_S5 which fluctuated between 3.8 and 5V.
Replaced U7941 and U7200. Now a consistent 5V on PP5V_S5. Still no power though.
Moving down the rails I got no PP5V_SUS.
C1802 and C1803 3.3V
ADAPTER_EN at R5085 0V
Very small patches of corrosion were found on a few probe points in the machine but no corrosion was spotted on any components.
Where should I go from here?
