    820-02016 - No Trackpad / Keyboard - Unable to restore via AC2

    Hi,

    Im facing keyboard and trackpad issues (no function) on an A2337 (820-02016 / MacBook Air M1).

    I have already tried the following:
    • Replaced the flex cable (between logic board and trackpad)
    • Tried another top case (same issue)
    • Replaced UT330, UT355, UT310, UT360 and UT365
      • IPD_SPI_EN_CON = 0.596
      • IPD_SPI_EN = 0.316
    Is it normal that "IPD_SPI_EN" is always 0V?

    And when it try to restore the MacBook via AC2 (DFU Mode) I get the following error message:

    What does AC2 error 16383 mean?

      A2681 Keyboard, trackpad and sleep?!
      by iMuhtaseb
      Wow it's been a while since I posted!

      This is a weird case, it has a history of liquid spill a year ago but customer did not want to replace neither trackpad or keyboard.. fast forward for today:

      A2681 turns on but not trackpad or keyboard feedback (or external keyboard and mouse) and then after a minute or so the Mac sleeps..

      It's a NOT a sleep sensor or trackpad or keyboard or daughterboard or anything else (I replaced all those); it's the logic board..

      Tested another locked logic board on customer's top case and it posted with keyboard and...

      Hi Guys,

      This Mac come with dead issues (severe water damage), now it’s turning ON except Trackpad and Keyboard not working.

      Already check and write down DM for JT400 and JT201 don’t find any abnormal value (I don’t have unit for compare).

      Already try,
      • Replacing Trackpad Flex Cable
      • Replacing New Trackpad
      • Replacing Little Board (Daughter Board)
      • Try using New Keyboard
      Still no change at all, Trackpad and Keyboard not working.

      So I check “Power Load Switches” and this is all the numbers,
      UC830 > 1 = 3.297V ; 3 =1.757V ; 4 = 3.798V...

      Macbook A2338 M2 (EMC 8162) keyboard not functioning, trackpad is working
      by Vliegenier04
      Hi! This Mac has been an headscratcher for me, I can't seem to figure out the issue. The Macbook has gotten water damage to the front of the keyboard connector and battery connector. The keyboard connector was dead, by which I mean it was completely corroded and I have replaced it with a brand new one.
      I have verified all the pins are connected to the main board and the main voltages (PP1V8_AONSW_KBD_ISNS and PP3V3_AON_KBD_CONN) are both present, with and without keyboard attached.

      Unfortunately, the keyboard does NOT want to work, caps lock LED not functioning as well as any...

      820-00426 (A1398 2015) no trackpad, no keyboard.
      by nicocorradini
      Hi! I have this 2015 A1398 with 820-00426 board that's driving me crazy. It originally came because of charging problems (MagSafe Board roasted, also MagSafe cable, etc. After disassembly, clean and assembly, my assistant (literally) broke FL803 and other componentes. Obviously, no screen or backlight. After replacing them, and also the LVDS connector, and LVDS flex on the screen, the board started fine, charges, chimes, shows Apple Logo, but surprise: no more trackpad or keyboard.

      Important notes:
      -Click works, so, trackpad is alive.
      -Already tried with another trackpad,...
