    MacBook Air M1 820-02016 No Power 50mA

    MacBook Air M1 820-02016

    Hello group. The Macbook was flooded and someone was already tinkering with it, it doesn't show any signs of life. The track pad was also affected by water, but didn't find any shorts. The charger initialises usually 5V and about 300mA and at 20V 20-50mA, voltages as below:

    PP3V8_AON_VDDMAIN - 3.8v
    PPBUS_AON -12.3V then 12.0V and going down and cycles
    PPVDD_SOC_S1 - 0.62v
    PP1V8_S2 -1.8v
    PP2V5_AWAKE_NAND - 2.58v
    PP1V25_S2 - 1.22v
    PP3v3_S2_UPC - 3.3v
    PP5v_S2 - 5.2V
    PP3v3_UPC0_LDO - 3.3v
    PP3v3_UPC1_LDO - 3.3v
    PP1v5_UPC0_LDO_CORE - 1.59v
    PP1v5_UPC1_LDO_CORE - 1.59v

    The SOC heats up to about 20 degrees. Trying to force DFU through the jumper does nothing. Is it a faulty SOC?

      MacBook Pro 2018 with Activation Lock
      by envym
      Hi everyone!

      I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.

      I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...

      General question about MacBook power rails for repair.
      by SarcasticOP
      I am looking at an A2337 and found this for the order of power rails and what they do. Can this be confirmed before I dive into hunting down power rails that do not exist or are not neccisary?
      • PPBUS_G3H (12.6V-12.8V)
        • This is the main power rail that supplies power to the entire system. Check this rail first, as it must be present for other power rails to work.
      • PP3V42_G3H (3.42V)
        • This power rail is derived from PPBUS_G3H and is used to power the SMC (System Management Controller) and other essential circuits. It should be present if PPBUS_G3H is working correctly.
      • PPVRTC_G3H (3.3V)
        • This
