Have an A2780 that is not powering on.
The USB-C Meter doesn't negotiate past 5V. However it will he at 4.9V @ 0.012A draw. Then Jump to 5.05V @ 0.920A draw and keeps cycling this behavoir.
PPBUS_AON = 11.97V
P3V8AON = 3.805V
P1V8VDDH - 0.35V up to 0.45V cycling quickly.
PP5V_S2_MAIN - 1.7V up to 2.05V cycling
PPDCIN_AON_CHGR - 4.927V
I'm not familiar with these newer boards in terms of what rails to check but any help is appreciated.
