As you may be aware, the keyboard/ track pad communicate using the USB protocol prior to login and in recovery. They then switch to SPI communication after login. Therefore I would be look at the data function of the USB ports. If you have any sort ot drive with a data activity LED, you can see if there is any activity on the ports data wise.

Re: Macbook Air A2337 Schematic & SilkScreen – 820-02016 Schematic & SilkScreen (Prov
Yes, I just confirmed this on an actual logic board too. As far as I see it the schematic is wrong and this cannot be corrected AFAIK. Hence the board view is incorrect because I assume it is following the schematic. It's a tricky situation for @whizkidz...

Re: Macbook M1 Unlocked!
I bought this 820-02016 A2337 on eBay yesterday knowing that it had some lock that looks like the old EFI lock of earlier models. sickw(dot com) shows board as iCloud and MDM unlocked, so what is this lock shown in this device please. I am assuming that without the appropriate PIN code I will never unlock it? Thanks, I hate all this locking cr*p like we all do.

Re: Macbook M1 Unlocked!
Master Liu is a good tech but this is rubbish. Don't waste your time watching this cr*p. Macbooks now connect to Apple server to confirm serial number and iCloud status. Changing SN in the ROM chip will not fool the Apple server. Total waste of time like @Stephen says...Last edited by Pedro147; 08-01-2023, 08:58 PM.

Re: 820-02098 and 820-02443 brd and sch files
Not sure why some of you cannot see that both ZIP folders contain both .bvr board files and PDF schematics for both logic boards (820-02098 and 820-02443) They are both there, see here [url]https://*******/a/Nhw8zaF[/url]

Re: macbook 820-00239 20v no power missing pp3v3_s5
Hi @mon2, I just wanted to thank you for the info in this thread. It just helped me fix an 820-00923 board that I was having trouble with. I looked at U7650 because of what you said here and after measuring the PP3V3_S5 and PP5v_S5 outputs and the enables for those outputs, I thought that it might well have a faulty U7650 which it did. So thanks again for all the help that I have seen you give to people in here, I for one greatly appreciate it

820-02100 and 820-02382 bvr and sch files
I was fortunate enough to be given bvr and schematic files for these two boards yesterday. The board files are not available unfortunately, so please do not ask. Both FBV and OBV will open bvr files. Happy repairs and thanks to our benefactor who is generously supplying the community with these very late model files....
