820-01041 not available yet. Have to be patient.
Only the 13" leaked for now, 820-00850, but no one shared it for free yet apparently.OpenBoardView — https://github.com/OpenBoardView/OpenBoardViewComment

Hi, I found short on one of 6 black nand (total 1TB).
i removed all 6 nand ( voltages all ok) and now i want to program with JC P15 but for A1990 2019 there is only 512GB configuration.
I try A2141 1TB configurazion with TSB4228 but the position on pcb is different ( U9300 and U9400 is no stuff on A1990 but present on A2141 and U8800 and U8900 is no stuff on A2141 but present on A1990 )
macbook with A2141 configuration run on recovery but don't complete it.
anyone can help me?05-26-2025, 09:27 AM -
Hi, I am asking for a little troubleshooting advice.
The laptop seems to boot up fine. Caps lock is working, the touch pad has haptic feedback, and even the "charger plugged"-sound is present.
Power consumption is about 15-30W at boot and idles at about 20W.
Unfortunately, the display and the touch bar are completely black (No signal and no backlight).
I don't get a signal on an external USB-C display either. Also not in safe mode.
I noticed that only the left fan (from the bottom side, hinge on top) seems to spin up. I think... -
Hello,
I am currently working on a Macbook Pro A1990 (motherboard 820-01041) which is not charging.
The Macbook consumes 5V and 0.019A at USB-C. There seems to be a partial short-circuit on the PPBUS_G3H rail as I have 0V on this rail.
I've physically separated (by removing F7000 and F7001) PPBUS_G3H and the ISL9240 charging chip to see which side the short is coming from. Removing these fuses gives me 12.6V at the output of the ISL chip (PPVBAT_G3H_CHGR_REG).
However, I can't work out exactly why I don't have the PPBUS_G3H rail.
Here are the values... -
Hi i have one Macbook Air 2020 where touch ID is not working (it's not scanning fingerprints). Touch ID was working before, there is no error message during scanning fingerprint it's just not scanning on screen you can see only fingerprint but there are no red updates as when it's working. Power button is working fine.
I've checked boardview and also schematics but i'm not able to find anything related to TouchID ... i have similar issue on a2338 where there was problem with PP3V0_TOUCHID and after replacing UT610 it was working but here i'm not able to find anything related to...
