    Macbook Pro 14" 2442 with a repair attempt

    Hello,

    I just got this laptop that looks like someone already attempted a repair.
    Does anyone know what were they trying to do? Is it worth it to attempt to fix the failed repair?

    The laptop currently shows 5v 0.2amps, no sign of life.





    Thank you


    EDIT: PPDCIN_AON shows 5.15v, same as what my usb meter shows

    EDIT 2 : Injecting voltage shows heat here :

              MacBook Pro A2289 (820-01987-A) No boot or Display, but boots to DFU and shows status bar only
              by saisoni20
              Hi everyone.

              Recently got MacBook Pro A2289 with interesting behavior. Pristine condition, no water damage, no visual issues whatsoever. It has no image, no Caps Lock, no life except the fan is spinning. But it is able to connect to DFU mode and recognized by another MacBook. I tried to revive but the process ends when the MacBook usually should show an Apple logo with a progress bar and giving me error AMRestoreErrorDomain error 9. I don't have CPU Vcore.
              Now I can't able to connect to DFU mode either.

              On the USB meter I got 20V/0.9A power draw, and keep looping....

              General question about MacBook power rails for repair.
              by SarcasticOP
              I am looking at an A2337 and found this for the order of power rails and what they do. Can this be confirmed before I dive into hunting down power rails that do not exist or are not neccisary?
              • PPBUS_G3H (12.6V-12.8V)
                • This is the main power rail that supplies power to the entire system. Check this rail first, as it must be present for other power rails to work.
              • PP3V42_G3H (3.42V)
                • This power rail is derived from PPBUS_G3H and is used to power the SMC (System Management Controller) and other essential circuits. It should be present if PPBUS_G3H is working correctly.
              • PPVRTC_G3H (3.3V)
                • This
              ...

              A2941 Macbook air 15” - 5V 0a
              by obelix24
              I’m working on one macbook air 15” m2 that was water damaged.

              keyboard, lcd, microphone connectors were damaged so i’ve replaced all of them and without screen connected macbook worked fine. Keyboard &trackpad and also lid sensor was working fine.

              i’ve put macbook in shelf and order new screen so i can fully repair it.

              Now i got the screen and macbook stays at 5v 0a.

              i’ve tried if it’s not in DFU with another macbook but it’s not detected at all.

              i don’t have schematics so i don’t know where to start can someone help me?...
