I am looking at an A2337 and found this for the order of power rails and what they do. Can this be confirmed before I dive into hunting down power rails that do not exist or are not neccisary?
- PPBUS_G3H (12.6V-12.8V)
- This is the main power rail that supplies power to the entire system. Check this rail first, as it must be present for other power rails to work.
- PP3V42_G3H (3.42V)
- This power rail is derived from PPBUS_G3H and is used to power the SMC (System Management Controller) and other essential circuits. It should be present if PPBUS_G3H is working correctly.
- PPVRTC_G3H (3.3V)
- This
- PPBUS_G3H (12.6V-12.8V)

I’m working on one macbook air 15” m2 that was water damaged.
keyboard, lcd, microphone connectors were damaged so i’ve replaced all of them and without screen connected macbook worked fine. Keyboard &trackpad and also lid sensor was working fine.
i’ve put macbook in shelf and order new screen so i can fully repair it.

i’ve tried if it’s not in DFU with another macbook but it’s not detected at all.
i don’t have schematics so i don’t know where to start can someone help me?... -
Sorry,I'm using my phone right now and couldn't find any search bar to search on the topic of macbooks.
Few weeks back(mid may),I had bought a MacBook pro m1 A2338. It belonged to my friend's younger brother who was a graphic designer,he gave me this MacBook without any icloud account linked to it and I had so much work during that times that I only used it for storage while traveling for shoots (I'm a photographer). So long story short,his brother got involved in a bad accident and was in coma and then fairly recently they pulled out his life support. I mistakenly did an erase Mac and...06-20-2025, 09:43 AM -
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 — hoping someone here can shed some light.
🛠 Original Issue
The machine initially wouldn't negotiate 20V over USB-C — 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.
⚠️ New Problem: One USB-C Port Only Works in One Orientation...
