    [help]macbook air 820-01521...seems alive but it's dead! crazy!!

    I could only see 1.6A consumption; possibly with battery connected. What is the current consumption without battery? Can you post voltage on the coils?

    820-02098-A MBP A2442 booting without display connceted

    If the problem appeared after display changed, check for mechanical damage. Possibly damaged connectors, or knocked off components (near the board edge).

    A1466 SSD ISSUE

    It can be SMC issue. But keep in mind, SMC doesn't supervise any sensor in SMC bypass; no matter is thermal, or I/V sensor. Did you check mentioned lines for continuity?

    A1466 SSD ISSUE

    No schematic of its LIO board; use mentioned one as guide! The thermal sensor is the same. You don't need to identify LIO connector pins.

    820-3115 A1278 reset

    I think a Kon-Boot macOS version exists; probably paid version.

    A1466 SSD ISSUE

    Check continuity between R5370/1 and corresponding pins of LIO Finstack Temperature chip. You can use TMP 102 datasheet and 820-3057 LIO schematic as guide.

    "Q420 lines arent shorted" If no short, check its enable signal. It shouldn't receive enable signal when the output voltage is present.

    820-03286 (A2941) - No PPBUS_AON / Stuck at 5V

    Each one has series resistors on its output; RR7x2/3, 0 ohm, 0603 in size. Remove the pair for each chip and check if problem persists. BTW, write directly into bottom reply box, instead of clicking Reply button.

    A3114 Trackpad and keyboard not working

    https://drive.google.com/file/d/1nvjSmhSf3a1YMIJ4KwIwDXT7S6__gGVn/view?usp=sharing Are you sure the keyboard daughter board is good?

    820-03286 (A2941) - No PPBUS_AON / Stuck at 5V

    You should try replacing the amplifier chip.

    820-03286 (A2941) - No PPBUS_AON / Stuck at 5V

    "Faulty UC300?" You already said is shorted. Replace it and check all adjacent components and traces.

    A3114 Trackpad and keyboard not working

    I don't have any idea what board do you have. Is so complicated to post 820-xxxxx code???

    Macbook A2338 5V .400 Amps

    RN420-3 shouldn't heat up. These are discharge resistors for 2V5_AWAKE_NAND power rail. Q420 may be shorted, or it receives incorrect enable signal.

    A1466 SSD ISSUE

    Check continuity between LIO thermal sensor (finstack) and MLB.
