  • 820-00923-A ( MBP 13 touchbar) only charging one side usb c.

    Hi,

    Got this MBP 13 touchbar with water damage. Cleaned, repaired all short and components were damaged and now 3 of 4 usb ports are working fine. But 1 of USB-C only turn on and charge when plug one side. When up side down the connecter it's not detected. Already checked all componentes arroung fpc and nothing seems to be bad.

    Any idea?

    Do you get 20V on that USB-C in reverse position?
    Which is that port in schematic?

        Check continuity on board traces and give as a name in schematic.
        So machine works in that position, but no external USB device recognized when connected in that way?
        In such case, check CC1/2 lines for that port.
