Yes ALL_SYS_PWRGD present at 1.8V and both coils were measured at both ends, I just realized that PCH is heating up a little, mac sits at 20V 0.181A after a few seconds of connecting power.
Are we talking about the same same board?
I do have ALL_SYS_PWRGD and L8100/02 voltages are too low, both those coils dont have caps at either end, both have a resitor R8118 and R8102 afther the coil, then after the resistor there are caps, I measured both ends a few times and get the same result.
Upon further inspection I realized PP5V_G3S_CPU was only present in some part of the board, after making a jumper wire get connected to R8154 and now board boots up, your suggestions led me here, thanks a lot!
