Hi there. I have an Apple Macbook Air A2179 with water damage. It was not charging and was stuck on 5v. I removed the board, and there were corrosions on multiple spots I cleaned and resoldered using flux to make sure all disconnections connected back again.
Then I connected the charging cable to USB-C Meter and it started to use 20v 0.12 amp. Amp started to go up and back to 0.12. Amp usage was going to 0.35 and then back to 0.12 and then up to 0.55 and back to 0.12, t9 0.70 and back to 0.12.
The CPU area got hot, and it felt like the mainboard booted. I connected the board to Apple Configurator to see if it is in DFU mode or not. It did not detect it. I assembled the board on a different working A2179 body and started charging and using an amp 2.6amp. The fan was silent, and the screen was black. I connected my iPhone to another USB-C port and the iPhone was taking charge from the Board.
But the board was making a ticking sound near L7400. I removed that coil and powered the board. The ticking noise is gone. I put in a new L7400 coil, but the ticking sound came back. I need your guidance to get the issue fixed.
Thank you again.
Let me know if you need anything else.
Regards
Zeyd
