    820-00138-a A1398

    Good Morning. (Where I am anyway.) Have Macbook Air 1398 with 820-00138-A with liquid damage. Does anyone have schematic and boardview for this board. Thanks in advance for any help.

            I'm working on a 820-00138-A board that was liquid damaged.
            It's booting but goes into panic-mode (loud fans) and the cpu and ram is getting very hot.
            I have 19,6V on PPBUS_G3H, this is too much, it should be 12v.

            Does anyone has any idea what I can do next?

            Thank you

              Shorted high side MOSFET for the PPBUS_G3H buck converter, so you get the DC in voltage on PPBUS_G3H.

                    Thanks but the board view you provide is a bit different than 820-00138-A board I have and the tracks doesn't match, in special ti the SSD control IC's side. Does anyone has the correct brd for this board please. Thanks in advance.

                          Hi

                          Does anybody have a boardview for the 820-00138-a?
                          820-00138 is not the same as 820-00138-a.

                          Thanks

                                Schematics in this thread is the correct one. The touchpad connector J4801 in the schematics is wrong though, use 820-00163 schematics for the proper pinout.
                                The boardview in this thread is for 820-3662, it looks similar to 820-00138 but the SPI ROM and touchpad area are different. Use 820-00163 again to troubleshoot touchpad area.

                                The correct 820-00138 boardview may be available, but I haven't seen it yet. Most websites sell the 820-3662 but labelled 820-00138, be aware of this scam… (same for 820-3536 sold as 820-3476, 820-00163 sold as 820-00426 and maybe some others)

                                        eDP port has big difference.
                                        Backlit control is organized in other way.
