820 00165 no power, board has 2 tiny spots of liquid damage on Q7630 and U1930. Magsafe lights, 8.57v on PPBUS. PP5V_S5 is present, when I measure voltage for PP5V_S3 at L4011 and R6414 I get 0, but when I take a measurement at L4605 I get a reading that jumps all over, very strange. I have replaced U1930 due to it looking like shit.

Do you get 3V3_SUS?
If not, check PM_SLP_SUS_L.
PM_SLP_S4_L pulsing at least?
L7520 should pulse at same time.
If yes, check if other coils pulse too.
Is better to check toggling SMC_ONOFF_L signal; use R5115/16 pads for this...Last edited by 2informaticos; 11-07-2018, 12:29 PM.
