    820-3315 - PP5v_s5 floating

    nothing friend! I removed the components you mentioned and the same thing! this board is crazy! When in doubt, I changed the R7267/68 or u7200 again

    820-3315 - PP5v_s5 floating

    I found something strange! R7267/68 that I had tested, now they don't go up to the correct value. They stay at 5k, so replace both. They were OK, I put the charger to test, it didn't work. They went back to 5k.

    820-3315 - PP5v_s5 floating

    I had already checked these components, all ok. The R7367/68 would be the R7267, right? all ok L/Q7260.

    820-3315 - PP5v_s5 floating

    No history. Some oxidation spots, which I've fixed and tested. Nothing line related. Yes, I only tested the board. With a short between 1 and 6, the PP5V stabilized.

    820-3315 - PP5v_s5 floating

    Line PP5v_S5 and PP3v3_S5 floating 0 to 3v, I looked for a short on the secondary lines, I did not find it. I tried to change the U7200, without success. It didn't work with SMC bypass, it didn't work! Stable PPBus at 12.6v. SMC_PM_G2_EN is floating

    820-01521 - dead

    Board is perfect, no oxidation or short. It has 20v and draws 0.2a from the source (without battery). Trackpad has click. In DFU mode, I tried Revive and Restore, both complete without error and Configurator gets padlocked. Audio card is perfect, but I tried to connect with it disconnected, it...

    820-00164 - system starts, hangs on user

    Monterey installation was to get the firmware updated again. Tried with external SSD with El Capitan and High Sierra (Mac shuts down when loading system), Catalina (system starts and hangs on user), all with internal SSD disconnected. Yes, I used BIOS clean ME. The system works in safe mode...

    820-00928 - 20v but won't turn on

    the board no longer pulls 1.8a. A similar Mac came in to change the battery, I took the opportunity to compare the coils in diode mode. Little difference, an example: the good board the L7211 appears 0.003, the bad board 0.007
