820-00244 (2016 MacBook 12”) originally with a bad CD3215.
Got it replaced along with the charger port (shorted) and got 20V but board is sitting at .18A
I am getting All_Sys_pwrgd, PPVCC_SA_S0 and CPU_VR_Ready but not PPVCore_S0_CPU.
U7100 is looking ok. I assume that getting All_Sys_pwrgd is telling U7100 to shout out the 2 S0 voltages?!
Resistance to ground on Vcore is 5ohms which is matching a known working board.
I understand that there is a high probability that the CPU is out but since the resistance to ground is fair and the original problem was the CD3215 I am not giving up on this one just yet.
