    Macbook pro M1 A2338 820-02020 just 5Volts

    Hello, I have a MacBook Pro Macbook Pro M1 A2338 820-02020. It got liquid. When I connect the power pack, only 5 volts and 0 amps are displayed! There is nothing to see on the board.

                    Hi. The connector looks good.

                    Can you review the cable that is being inserted inside this connector ?

                    Are the keyboard cable contacts the proper pitch ?

                    What is the logic board 820-xxxx # that has this connector ?

                      The cable and the connector are defective! I want to swap the connector on the keyboard but can't find it on the internet!

                        Both are available. Which logic board markings ?

                        Is it for the 820-02020 (A2338) or another ?

                            Yopolean (Dynamite?) is a good vendor. Have bought from them before a number of times. They have this cable.

                            Here are other shops:

                            https://www.aliexpress.com/wholesale...psort=1&page=1

                            For the connector that is defective - is that on the KEYBOARD or logic board ?

                            If on the keyboard, then the keyboard should be replaced.

                              on the Keyboard. Changing the keyboard isn't that great because of the rivets.

                                Yup, been there and done that. Alternative is to locate a defective keyboard or source a new one to lift off this connector. It will be a bit difficult since these style of connectors warp (melt) very easily.

                                I would suggest a blad soldering tip + lots of flux and gently lift one pad off at a time till the connector is lifted. Hot air will warp / melt and kill the connector.

                                      If you see 5 volts, then the CD321xx ICs are not working.

                                      Check the LDO rails on each controller first.

A dear friend of mine gave me a macbook pro M1 A2338 that only works with an external screen. With the internal one, no backlight or image. Only the external display is detected from the system settings.

                                        I analyzed the logic board, it shows no sign of liquid or visible damage. I then moved on to examine the logic with the thermal camera and found that the UP701 chip was...

                                        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...

                                        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?...
