Clean Board, however 20v BUT 0 mAh

PPBUS_G3H = 12.56V
PPBUS_HS_CPU = 12.56V
PPBUS_HS_GPU = 12.56V
PP3V3_G3H = 3.3V
PP5V_S5 = 2V to 5V in Loop!
PP5V_S3 = 2V to 5V in Loop!
PPBUS_HS_OTH5V = 12.56V

Any hint from here?

Do you get pulse on all secondary voltages, or S3 at least?
Also check ALL_SYS_PWRGD.
