Yes it is an original charger. But I currently dont have another device to test if the charger itself is ok or if it has been killed with the dead U3100. But at least it delivers the 5.20V on PPVBUS_LIO. I guess I will try my luck with reflowing U7000. If that doesnt work i will order a donor...

SMC_BC_ACOK is at 0.002mV when using the USB-C Charger. Or do you mean when i Inject PPBUS_G3H? I will try a reflow on U7000 if that doesnt´t work i will order a donor board from Aliexpress or does the Chip here Work? https://store.rossmanngroup.com/e8-isl95530hiz.html

I tried injecting 3.3 Volts. The PP3V3_G3H Line pulled about 50mA from the Power Supply. I couldnt find anything that gets warm. I also tried inserting 8.6 Volts to PPBUS_G3H. When I did this i successfully got PP3V3_G3H and PP5V_G3H. I Get 0.2-0.3MOhms to Ground on PPBUS_G3H Do I see correct...

I will try that, but before i do so i want to confirm the following. I noticed I also dont have PPBUS_G3H. Am i right with the assumption that this has to be there before I can even get PP3V3_G3H or PP5V_G3H? I measure only 1.4mV and 3.8KOhms to ground for PPBUS_G3H. The Line has a Capacitance...

Thanks for the quick reply. PPVIN_G3H_P3V3G3H is at 5.20V CHGR_LDO_P5V0 is at 5.0V Around U7000 i couldnt find a full short but on C7966 i measured on the PPVCCIO_S0 Pin 193Ohms to ground which seems a bit low.

Hi there, i have an Macbook 12inch 820-00244 which had a Water Damage. I have already changed U3100 and Q3100 because it had a short on PPDCIN_G3H. When i Changed U3100 i might have ripped of the TP_UPC_XA_DBG_UART_TX Pin. But i couldnt find it anywhere else on the Boardview. Is this Pin doing...
