Good afternoon.
I got an 820-3476 that did not turn on: ppbus gave 0.60V.
I reballing SMC and it turned on but it had a graphics error: the system detects 15mb on the graphics card and 42 "on the screen.
I have tried 3 SMC's from donor boards and none works: it only gets started with smc bypass.
I connect the charger, green light, orange light, fan rotates 1-2 seconds and stops.
ppbus_g3h - 12.52V
PP3V42_G3H - 3.41V
PPVRTC_G3H - 3.41V
PP5V_S5 - 5V
SMC_LID - 3.41V
PP3V3_S5 - 3.32V
Thanks in advance.
