Seems like something in WIFI chip area is draining the battery, see here: (Thermal picture was taken while MacBook was in sleep mode)

Hi, I have an A2337 (820-02016) which is draining the battery while it is sleep mode. (Like 20-30% during the night) Note: - Battery has 100% health, so basically new.

Im getting the Apple logo (without progress bar) after while it disappears and I just see a black screen (backlight is on)

I have compared the AC2 restore logs with a working one …. Working one: [19:22:57.1704] Finished Recovery Restore Phase: Successful [19:22:58.7522] Recovery mode device disconnected [19:22:58.7522] Device removed when in state Restoring, moving device to transition state [19:22:58.7522]...

Replacing the trackpad fixed the MacBook - was able to complete the AC2 restore. (Found out that the trackpad was shorted)

How to identify a secondary power rail? I have checked the logi wiki, couldnt find an answer: https://logi.wiki/index.php/M1_MacBooks

Battery is nearly fully charged. (PPBUS_AON = 13V - with battery) still unable to restore. Do you mean the S1 rails?

macOS finder restore logs: BEGIN: RESTORED:[0x0647] cleanup_check_result [21:16:52.2653] restore-step-ids = {0x1103067B:61;0x11030635:67;0x1103130C:72;0x11030647:75} [21:16:52.2653] restore-step-names =...

I’m able to see the “restore screen” on the Mac but it’s not possible to restore it via AC2 (DFU) - ends always with error message 4014. Battery is charging, so I think the CDs are fine. Yeah I have checked it on F5200. I have also the restore logs from finder (macOS Sonoma). [19:53:17.6214]...

Yeah changed only CD3217 chips. (Also put back the original chips) Is 11.98V normal on PPBUS_AON (without battery?)

Yes, without battery connected. I have checked them, both were good.

I have replaced both CDs. (Took them from an A2337 donor board with correct order) Any idea what else can cause the low PPBUS_AON? Are the CDs paired to the logic board? No, which lines should I check? (Hint needed)

Hi, after a CD3217 replacement the MacBook Pro M1 (A2338 / 820-02020) no longer boots into the OS and it shows the "restore" screen. I have noticed that PPBUS_AON is 11.98V instead of 12.3V, any idea where I should start? Note: - Device restore via AC2 doesnt work ... Error 4014. - PP5V_S2 =...

Sadly I don’t have a working one. DFU restore should complete even with no keyboard/trackpad functionally right? Edit: https://boards.rossmanngroup.com/threads/a2442-820-02098-no-keyboard-or-trackpad.64468/ here it was also 0V, so I think it’s normal. Edit2: What does AC2 error 16383 mean?

So IPD_SPI_EN should always be high even when I just take measurements on the logic board (without anything connected - except USB-C ports)?
