820-3115 pp5v_sus 0v

Hi,

Macbook Pro 820-3115. All rails except PP5V_SUS are ok.

Checked Q7840 and PP5V_S5 get 5V also get enabled signal but PP5V_SUS is 0. Changed Q7840 but still getting 0V on out.

Do you get all S0 voltages, including VCORE, only missing 5V_SUS?
Post exact voltages for Q7822/40.
Also post exact ohm value to ground at 5V_SUS rail.

Solved.


Finally it was shorted smc.
