  • 820-00165-A Orange light, fan spin

    PP3V42_G3H L7095: 3.425 V (pin 2)
    PPBUS_G3H F7140: 8.60 V


    When I plug in the mag safe, green light (3 seconds), switch to orange
    Then fan spin

    This is both WITH and WITHOUT battery attached

    ON the DC in board, I think I identified the "one wire" circuit components

    U6900
    1: 3.425V
    2: GND
    4: 3.40V
    5: 3.40 V

    U6901

    1: 3.395 V
    2: 3.395 V
    4: 3.426 V

    5: 3.426 V


    DC in board fuse : 14.92 V (? F6905 equivalent)

    My question is what direction to go in to solve the issue of the switch to the orange light.

    Which issue???
    That is normal behaviour...


    Fan spin, nothing more?
    Do you get VCORE?
    Did you test USB activity?
