    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.

                                  Yes I know.
                                  I'm trying to get a cheap keyboard.

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

                                      Check the LDO rails on each controller first.
