    Check the resistance to ground of PP5V_G3S (with no power to the board).

          I took the board from a work laptop and it does not match these parameters as in the picture! Here is a picture with real indicators of the working board!

              MacBook Air A1932 internet recovery loop
              by nikolayu
              I have A1932 that is going to internet recovery every time.
              i tried nvram and smc reset but it looks that MacBook is not reacting to that.
              i tried to restore it through DFU but it restarts in the middle of process and Apple Configurator does not show any error, just stays like in progress.
              keyboard is working because I can connect to WiFi but internet recovery always fails with 2100 or 2003 error.
              also won’t open option to boot from usb device.

              and I noticed that is not possible to turn off the MacBook. It’s always turning on by itself.

              ...

              Hi, I've never worked with a MacBook before, so I need some advice.
              I have a MacBook Air A1932 (820-01521). When I plugged in the charger with an amp meter, it showed 19.7V and 1.9A, which indicates that it's charging, but when I press the power button, it doesn't turn on. So, I disassembled it, disconnected the battery, and plugged in the charger again. It showed 19.6V and 0.04A, and pressing the power button had no effect—no current draw at all. Then, I removed the motherboard, connected the charger again, and got the same results. I took a multimeter and checked all the coils, and everything...

              Macbook A1932 Some Keys Not Working
              by astroboypaul
              Macbook A1932 had completely dead keyboard. I found liquid damage on circuitry on keyboard itself, and repaired it by replacing what i think was a 10k 0201 resistor (here's my post requesting schematic for keyboard circuitry where I included a photo of the resistor: https://www.badcaps.net/forum/troubl...ic-820-01294-a)
              Now most of the keyboard works and I can login, but the following keys don't work: Delete, "/', left...
