Hi
I, have an A1502 820-3476-A that that doesn't power on.
It has no greenlight, no fan spin, and only puls 0.2A from bench PSU.
I don't have PPBUS_G3H (0V), but I don't think that is shorted (diode reading is 0.125 and 8Kohm of resistance to ground).
F7140 seams to be OK.
On L7130 I get 0.66V
On PPVBAT_G3H_CHGR_REG I get 0.123 on diode measurement
Can you help?
