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.

[mitchw]

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.

Still looking for the schematics, on my board there is a problem with SPI circuit, but it looks they changed it completely (different level shifters) compared to the M3 Pro board.

Good luck, it can make repairs challenging with no board view and schematic

Thanks Bastien. I hope that we manage to get some good late model files this year.

I have been kicked off Facebook, by the French far-right movement. I'm working on 820-03160! I will be back soon with something pretty good

Sorry to hear that Bastien.

Message me in Badcaps and I can provide another method of contact, pretty sure that people do not want us communicating within posts here

This file is for board 820-02098-a, not 820-03400; the area near the battery connector is different.

Yes not sure if it's an 820-2098 (would have to take a close look) but it's definitely not 820-03400 is it. Boo, Hiss

it look like 820-02841 and bad news

Anyone please help me with the MacBook Pro A3401 schematic. the one already exists that belongs to A2442.

[Pedro147]

Anyone please help me with the MacBook Pro A3104 schematic. . . . .

you mean A3401 (820-03400) 2024 MacBook Pro 14" M4. There is no A3104 model Macbook.

Some people have posted in this thread what they say is an 820-03400, but it's not, there are no files available for that board yet.

Closest you can use is M3 820-02918 which is very similar in a lot of areas.

The schematic which is posted by others not matching.
