    A2141 5V 250 milliamps

    PP5V_G3S not present PP3V3_G3S not present PP1V8_G3S not present I'm sorry, what does that mean? "G3S" status not being present? And yes I use 96W genuine. I will see the customer if he's OK with erase.

    A2141 5V 250 milliamps

    A2141 came in taking 5v, 200-250 milliamps... I've taken some measurements and found PP3V3G3H_RTC reading a little lower than expected in diode mode.. I looked in the the thermal camera and found U6960 (PP3V3G3H_RTC VR) to be heating up.. I replaced it. Board still taking 5v 200-250 milliamps...

    820-02100 no backlight

    hello, this board came in for liquid mainly on the trackpad connector / battery.. PPBUS was shorted to ground until I removed the trackpad connector on MLB and it was gone.. I noticed that the backlight IC had minor corrosions around it.. I ordered a bunch of ICs online and replaced it.. the...

    820-00239 5V

    This board came in taking 5V only.. It had prior liquid and prior board repair.. the work was done on UB300 area.. and PP3v3_G3H cap CB300 was removed completely.. I suspected the liquid damaged that cap and Mr. repair man just popped the cap and it worked.. for a while at least and now its...

    820-02020 A2338 Restore/Revive Failed

    PPBUS without the battery = 12V PPBUS with the battery = 13V Both USB-C ports switch to 20V with and without battery.

    820-02020 A2338 Restore/Revive Failed

    One thing I've noticed before I return the original ROM data is that the ROM is still erased as it is.. the restore/install has not even reached the process or the segment where it writes on ROM. Both ports behaving the same. 20V 0.0A PPBUS = 12v PP3v8_AON = 3.3v PP3v3_S2 = 3.3v PP3v3_S2_UPC =...

    820-02020 A2338 Restore/Revive Failed

    That's a remarkable observation on your behalf. It's taking 5v with 0 amp. I tried another charger and it switched to 20v whilst 0 amps. I returned the original ROM data and its still taking 20v 0 amps (it went back booting to the apple.com/restore link).. I don't know how I skipped this...

    820-02020 A2338 Restore/Revive Failed

    - SoC ROM erased - Battery connected - Power cable plugged prior to DFU cable (power cable was getting 5.2V stable no amp draw) - MacBook was in DFU mode; restore process started - Error 4010 I tried another round and still getting 4010.

    820-02020 A2338 Restore/Revive Failed

    Update: reprogrammed SoC ROM with clean BIN. After restore it gave me error 6 (while I think it lasted longer in "Installing..").. I restored another time and it gave me error 100. (still refusing to enter boot select)

    820-02020 A2338 Restore/Revive Failed

    A2338 - Pristine condition.. I took out of the board and inspected it.. nothing.. as if the computer is barely used even. Anyway, customer said they tried erasing/formatting it and it got stuck on Apple logo preventing to go further.. I asked them why they tried to erase it from the first...

    820-01949 with bad CD3217

    Ok I've taken the CD3217B12 from the M1 820-02020 and it has resolved the issue. I'll add that to logi.wiki or repair.wiki

    820-01949 with bad CD3217

    That cycle is apparently caused by the DC-in flex board.. now I'm stuck and I believe a need a CD3217B12 from the same model

    820-01949 with bad CD3217

    I went ahead and took of a CD3217B12 from 01700 and swapped it with the bad U3100-T (CD3217B12) on 01949; both ports on the left side now cycles whilst at 5V..

    820-01949 with bad CD3217

    Hello, A 820-01949 came in with one port not working at all and all three giving 5V.. I marked the bad CD3217 and it was U3100_T. I was able to verify it was bad by measuring PP5V_S4_XT_USBC; it was 0.045 (diode mode) shorted to ground.. where it should be 0.200+ My question is; I don't have...
