    A1502 restarts with battery connected (without battery no problems)

    Hello everybody,

    I'm working on a A1502 (820-4924A) that keeps restarting when the battery is connected. I've already tried a new battery. The problem also exists when the charger and the battery are connected.

    Without a connected battery, the machine runs without problems.

    Sometimes he brings a message like "Your computer restarted because of a problem". Most of the time he restarts without any message during booting up (endless loop).

    Does anyone have experience with such a fault?
    Thank you for every tip.
