I wish. I actually have one coming in for repair later today so hoping that A2992 820-02918 is similar enough.

Are you sure the board number is 820-03400 and not 820-03440. Just hoping I did not make a mistake on the LogiWiki entry for this model

It is 820-03400-A.

The M3 Pro board (820-02918) is similar, but has quite a few differences. I wasn't able to help with it much...

Thanks for confirming the board number, I'll correct my LogiWiki entry.

I just got that machine in late today and see that you are correct. Opps

mitchw did you manage to fix your board? Luckily mine all works except the keyboard backlight so hopefully the 820-02918 sch / boardview helps.

Sure, no problem.
Sadly I didn't fix it, but I am almost certain that the board is not at fault.
It works, but I have no keyboard / trackpad... Also lid sensor doesn't work but I think this a separate issue.
Until I replace the trackpad and lid sensor with known good units, I can't be sure abut the logic board.
