Have a liquid damaged 15" Retina. I'm going off the Schematic and BV for an 820-3662 which isn't exactly the same, seems like schematic isn't available yet.
I have magsafe lights but wont power on. I can feel U7330 getting hot, will order in and replace, culprit of my PPBUS_G3H??
PPBUS_G3H - 0.6V
PP3V42_G3H - 3.38V
PP3V3_S5 - 1.13V
SMC_BC_ACOK - 3.2V
PPDCIN_G3H - 20.5V
Q7130
PIN 1/3 - 0.643V
PIN 4 - 0.83V (CHGR_UGATE)
PIN 5 - 19.88V
Q7135
PIN 1/3 - GND
PIN 4 - 5.07V (CHGR_LGATE)
PIN 5 - 0.648V
