Hi everyone,
I have a MacBook Air 2015 (820-00165-02) that had some liquid damage. It was working for a while only on Adapter power, but that stopped working. Thunderbolt (external display) did not work. There was a bit of corrosion on the board, and I've cleaned that up. The adapter light does not turn on when I plug it in.
PP3v42_G3H: 3.42V
PPBUS_G3H: 0V
PPDCIN_G3H: 16.4V
PPDCIN_G3H_INRUSH: 0V

I have a 13 inch MacBook Air 2017 that does not show any life, however, there is activity from the MagSafe light going from green to orange and staying. Normally, this battery works perfectly fine and it can actually charge the battery as if I were to leave it alone it would change to just green, however, this thing does not boot up at all, I was told the computer was at 30% and then it randomly shut off.
Some voltages:
PPBUS_G3H - 8.5V
SMC_PM_G2_EN - 3.42V
PP3V3_S5 - 3.32V
PP3V42_G3H - 3.42V
PPDCIN_G3H - 15.18V
PP5V_S5 - 5.04V

Hi there i have a Macbook Air A1466 board number 820-00165-A. No power, and has Orange light when plug in to charger. SMC is working and the Fuse is good. Found a Short and removed. But still there is short on mosfet. The short leading to Capacitors near Processor.
- 2 Mosfet Near The Processor Is Shorted. (Already Tried Injecting 1V, draining 0.07A) Unable to shop the shorted area. Marked Blue.
- Already Checked Big Capacitor below the processor. (Good Capacitor) Marked Blue.
- Found a short and solved the issue. ( Red marked Big Cap)
