    MacBook Pro 13'' M2 A2338 USB doesn’t work

    Hello,
    I have MacBook Pro 2022 M2 with MB 820-02773 and it is completely dead. When I plug USB thru USB Voltmeter (FNB58), the Voltmeter turns off. I don't have any voltage on any pin. Looks like undetected. Should I replace UF100 and UF000 first? I don't have any idea how to start repair without voltage. There is no water damage or visually broken components.

      Attach the power adapter -> measure the voltage to ground of PPBUS_AON @ fuse F5200. Check both sides of this fuse.

          Checked. Fuse is ok. There is no voltage on both sides.

          edit: after several connections and disconnections, there is now a 12V voltage at the fuse. I also have voltages of 3.3V and 5V. Strange, but it still doesn’t turn on.

              ================================================================================

              I recommend analyzing all voltages of the U5200.
              As it is BGA, use the components around it.
              UF300
              UF350
              FF200
              FF201​

                  Apple Macbook Pro A2338 EMC8162 lid sensor doesn't work
                  by veedo
                  I have an Macbook Pro A2338 after small liquid damage, all working fine but keyboard was sticky so I have replaced palmrest for genuine second hand and now lid sensor doesn't recognize when I'm closing the lid. Display is always on, can't find sensor for that model, can someone explain my how does it work, where that flex is if there is any.

                  Maybe that the motherboard issue, not sure where to start.

                  Thank You

                  Liquid damaged macbook A1466 fan spins, but doesn't turn on.
                  by redbaron1007
                  I got a tricky one today in the form of a macbook air A1466 820-00165-A that will recognize the charger and turn the light green then back to orange and the fan will spin constantly, but the system won't power on. The screen never turns on, it doesn't make the bong noise it's supposed to, and pressing the power button doesn't do anything. When I took the board out to visibly inspect it I only found one spot of corrosion on the bios IC. I pulled the chip, cleaned it and the area with IPA and put fresh solder on both and put the bios chip back on, but when I went to test it again it still does the...

                  MacBook Pro A2338 [820-02773] No Audio (Speakers and Microphone)
                  by classicandy
                  Hi Everyone,

                  Please, I have a MacBook Pro A2338 M2, board number : 820-02773. The speakers and the microphone of the Mac are not working and I need assistance in fixing.

                  UR730 got damaged and short-circuited the motherboard. After removing the shortened IC; before and after putting the new one I ordered, the speakers [specifically the other one not affected by this IC] and the microphone are still not working. I do have sound through a Bluetooth speaker device or when I connect a headphone with microphone to the jack 3.5mm input. Also, media files do not play unless ​a...

                  MacBook Pro M2 A2338 with PowerSupply it is running, "X" on the battery symbol and FAN is running permanently
                  by Schluchti45
                  I have a MacBook Pro A2338 M2. The MacBook runs with the power supply unit. The fan runs permanently and the battery shows the message “Service recommended”.
                  I have already replaced the battery with a new one, but this has not helped. I have also tried DFU and the system restored the error remains the same.
                  Do any of you have any ideas where I could look or how I should proceed here?...
