Sorry, I meant to write 0.41 and not 4.1. ? It measures 0.41

yes, I measured diode mode. PPBUS_G3H to ground is 4.1V and diode mode between F7000 pads is 0V.

0V at F7000 Edit: or do you mean PPBUS_G3H to ground? That is 4.1V

Hi I replaced U7000 now. P_IN 20.17V AUX_DET 5.01V DDA 5.13 V DDP 5.13V MPM_PBUS 19.81V VR1_3P3 3.327V EN_VR1 5.12V SMC_RST* 3.331V AUX_OK 3.331V AMON 15mV BMON 2mV for CBC_ON I could not find a probe point on the board view. PPBUS_G3H is still 0.77v.

Thank you for your time so far. The voltages I could measure are: PM_EN_P3V3_G3H 5.00V PPVBAT_G3H_CHGR_REG 0.776V PPVBAT_G3H_CONN 0.776V TBA_BGATE 0.2mV TBA_BOOT1 4.70V TBA_BOOT2 4,74V TBA_CSO_N 0.776V TBA_CSO_P 0.776V TBA_GATE_Q1 2.8mV TBA_GATE_Q2 0V TBA_GATE_Q3 0V TBA_GATE_Q4 2.8mV TBA_LX1...

diode mode PPBUS_G3H to ground is 0.422V

Hi, I am working on an 820-00239-A. Charger was stuck at 5V, after replacing UB400 I'm getting 20V 0,0A on other 3 ports, the port UB400 is responsible for is still stuck at 5V. PPBUS_G3H is 0.77v. PP3V3_G3H is 3.4v. Can UB400 be responsible for PPBUS_G3H not being created properly?

Bought this thing on ebay a while ago. Came without HDD, HDD cable, ODD, ODD cable. Trackpad cable ripped, many screws missing :confused: Screen has signs of liquid damage, most likely dead. All 3 Backlight connector pads corroded, backlight fuse blown. Removed screen connector from board and...
