                  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!

                          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...

                          I am trying to repair the laptop mentioned in the title. I have been searching posts looking for readings similar to mine but cannot find any. I am fairly new at this so please be gentle 🏳

                          History:
                          No water damage, screen cracked. Laptop doesn't draw any amps on USB meter from either USB C port. Removed the board, same no amp draw. No standby light on the board. Apart from dust board looks great! No obvious visible burnt components. At the moment I dont have a Mac charger, its on the way. I am using a samsung USB C charger which should get the board on...
