Sorry, my bad you are right , thanks for explain me. PPBUS_G3H = 0.437

PPBUS_G3H = 433 OHM

Hi everyone , I need help with this equipment, Macbook pro 820-00840 don't turn on. voltage on both ucb-C ports = 5.21 V. 0.10 A PP3V3_G3H = 3.4 PPBUS_G3H = 0.0014 PPDCIN_G3H_CHGR. = 5.195 PPVIN_G3H_P3V3G3H = 4.8 Thanks

Hi everyone , I need help with this equipment, Macbook pro 820-4924 suddenly stops work PPBUS_G3H. =12.37v PPDCIN_G3H = 15.05v PP3V42_G3H = 3.412v PPVRTC_G3H. = 3.36v PP5V_S5. = 5v PP5V_s4. = 0v S4_PWR_EN = 0V PP3V3_S5 3.3V Thanks for any help.

Thank you very much, the macbook is working, the keyboard was short-circuited due to water damage

I already checked and yes , it does usb activity

both L7210/20 = when I plug the charger starts at 1.078v and after few seconds downs to 0.670 and do not change any more

L7210 = 3.7 ohms to ground L7220 = 3.7 ohms to ground

PPBUS_G3H = 13.05v 3V3_S5 = 3.360v 3V3_SUS = 3.358v coffee was spilled on the keyboard , but the board is clean I inspected with a thermal camera and u7210 and u7100 were heated thank you very much for the files

Hi everyone , I need help with this equipment, I don't have the schematics or .brd file , the board get 20.v and 0.87ma after that goes to 20.3 and 0.17ma thanks

Hi everyone , here an iMac don't power on only one led on , no chime , no spin, no light on mouse PP3V42_G3H 3.43 PP12V_G3H. 12.09 PP3V3_S5. 3.31 PP5V_S5 4.99 PP12V_S5 12 PP1V5_S3 1.5 PP3V3_S3 3.3 P5V_S3 5.10 PP12V_S0...

Done i have already changed it and now in diodo mode 1v1 has 515 but it has the same behavior not 1v1 , in addition to that, i figured out that R3034 UPC_XB_HPD_RX and R3033 UPC_XA_HPD_RX has 0 ohm and the schematic shows that both 100kohms, i have already changed too for 100kohms , the board...

Thanks for the welcome. - The board was with a voltage problem varying between 5v and 1v in PP20V_USBC_XA_VBUS in U3100 thus i replaced U3100 , after that is the actual condition - Yes is the same behavior on all 4 ports now - All 4 has similar values and 1v1 ,1v8 and 3v3 voltages are...

Hello everyone. I'm new in the forum, and I am not a native English speaker so just in case I make mistakes writing, i'm using google translate. I hope to find some help here, thanks PP20V_USBC_XA_VBUS = 5.207 v PP3V3_G3H_REG_R= 3.418 v PPVIN_G3H_P3V3G3H = 4.886 v PPDCIN_G3H_CHGR_R =...
