    A1989 820-00850

    Dear friends,

    Below is the link to my YouTube video.
    I have an A1989, 820-00850, which has 20 volts, its amperage, and which boots up without displaying anything on the screen unless I press the "Option" key.
    External drives can be seen if they are connected, but I can't access them.
    I can't do anything except that.
    I don't have your knowledge to resolve this problem, if a solution exists.
    Can you help me please?

    Sincerely, Pascal

      MacBook A1989 No power
      by tommy97
      Hi,

      I’m having an issue with an A1989 board after water damage, it’s stuck at 5V 0.20A. I’ve checked the measurements, and all readings are the same across all four CD3215 chips. I replaced them one by one (using chips from a donor board), but nothing has changed.

      I don’t need a fully functional board, as the repair is only for data recovery purposes.

      MacBook Pro A1989 820-00850-A not powering on
      by ErinV
      Hey everyone!

      I have a MacBook Pro A1989 with a 820-00850-A board that recently stopped working. I used it overnight to charge my phone, in the morning it didn't turn on, I assumed flat battery but now won't charge and doesn't start at all.

      I have fully dissassembled it, when disconnected the battery reads at 0.012V. Even with the battery disconnected the laptop doesn't boot.

      The diode voltages around all 4 CD3215's seem fine.

      For all CD3215 (UB300, UB400, U3100 and U3200) I read just above 5V on PP20V_USBC_TA_VBUS, 3.3V on PP3V3UPC_TA_LDO, 1.8V...

      Macbook Pro A1989 - No image, working fine with external monitor
      by Madoy104
      Hi everyone,


      I have a MacBook Pro A1989 that was likely exposed to liquid. It doesn't display an image on the built-in screen, but the screen is backlit (you can't see the Apple logo or any other elements when held up to light). The laptop provides 20V and 1.5-2A, and it works fine when I use it with an external monitor. Currently, the connector for the display (J8500) is disconnected. I'm writing to ask for help in diagnosing the issue. I've heard that when the J8500 is exposed to liquid, the processor pin responsible for the display might short-circuit, and I'd like to know...
