In this video; we had a MacBook Pro A1398 with No Power. The board was liquid damaged, using a multimeter, we confirmed that some of the S0 rails are present, however, PP5V_S0 was 1V. Q8060 is the 5V regulator, but only if all working conditions are met, this includes voltage at the source and the GATE being allowed to open by Q8052, which is dependent on the P5VS0_EN signal, this was also present, but still no 5V at the output, when then checked for a short, and found none, then we concluded that our issue is Q8060 because all working conditions required by the chip are all present. 5V was restored after the replacement and the board is now functional.
