    820-00928 5v on port PPBUS 0V

    After replacing UB300 and UB400 mac starts fine, but now I have critical software error, I isolated this error to the board since it also happens with just the LCD and power cable connected, normally I replace U4200 and most of the time this fixes it, but not on this one.

    Yes OG 87w and OG cable, same thing with a different charger. Checked U7000 resistors and diode mode around but all seem ok. Also replaced U5000 but same thing. If I leave the board alone for a long while the board will start but only that one time, if I unplug and plug again the problem...

    820-00928 5v on port PPBUS 0V

    This board did boost to 20V a few times and started up in my bench alone a few times but not it is back to the original problem, ports only take 5V and PPBUS stays at 0V, clean board. R7020 5V in all pads U7000 replaced already from same board just in case Q7030 and Q7040 replaced and same.

    820-02098 5V

    Board came with a short on PP5V_S2SW_USBC23 both UG400 and UG800 were shorted, after replacing both of those from same donating board I now get 5V on all ports, but in the port where I replaced UG400 if I connect the power cable there PPBUS is 2V the other ports give me 12V PPBUS, I tried 2...

    MacBook Air M3 - M4 DFU Restore Onboard

    The reason I am here is because that is what I was expecting, but not in this model, I tried with another one that is also working, but same problem. I will report back if I get any findings.

    820-00629 Audio problems

    Clean board, when you try to use the keyboard to move the volume up or down the audio icons comes up with a forbidden sign. I already replaced the Audio IC U6300 and have tried with the audio jack connected and disconnected and same thing.
