MacBook a2289 (820-1987-A) Stuck a 5.17v 0.00a

[Shantiche]

Help please. Customer brought the device in stated it stopped taking charge a week ago. He tried all new chargers. No corrosion on logic board.

First of all, welcome to the forum!

Machine doesn't charge battery, or doesn't turn on at all?
What is PPBUS_G3H exact voltage?
Also check diode mode to ground on it.

 

[Shantiche]

PPBUS_G3H voltage = 0.01
diode mode = 0.7

 

[Shantiche]

PPBUS_G3H voltage = 0.01
diode mode = 0.7

0.001*

No need to specify milivolts; good enough to say 0V (for voltage).

Remove F7000 and check C7050 voltage.
If still 0V, then post U7000 basic voltages; P_IN, AUX_DET, SMC_RST_IN, VDDA/P, SMC_RST*, EN_MVR, A/BMON.

Check diode mode to ground at 3V3_G3H_RTC too.
