Hi everyone,
I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck โ hoping someone here can shed some light.
๐ Original Issue
The machine initially wouldn't negotiate 20V over USB-C โ stuck at 5V.
Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.
I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

I received a 2013 Macbook Air A1466 820-3437-B motherboard with serial number C02L6GQ9FSV8 that came in WITHOUT a bios chip. I got a new bios chip and reprogrammed it. Macbook now powers on but doesn't boot the SSD. I've flashed a ton of bios but still same problem. Windows installation works with this Macbook but never a mac installation. Unfortunately, since I didn't receive this macbook with a bios chip, I don't have the original bios. What can I do now?... -
Hello all,
I am repairing a Macbook A2337 and i have a problem
The Macbook is stuck in restore as someone before me tried a DFU restore and bricked the device, now i can't do a restore as AC2 throws error 1 which is related to the trackpad.
When i turn on the device i get the trackpad click for a few moments and then nothing, i tried 7 trackpads and 7 trackpad flats, i know all 7 are functioning okay, especially one as i use it for testing and DFU restore.
I inspected the whole board and everything seems fine.
Can anyone help me as i didn't fiddle with trackpad... -

Hi guys,
If I unplugged the battery and the charger, then plug the battery then the charger, it charges without problem.
Then if I unplug the charger and plug it back, it won't charge anymore.
In the first case, main voltage is regulated at ~12.5V and charges the battery.
After unplugging the charger, main voltage drops to battery voltage at ~11.5V.
After replugging the charger, main voltage stays at ~11.5V and won't go up to ~12.5V again.
I found C520A (2.2ยต after current sensor from USB-C source) completely burnt and removed it properly. I cleaned...
