  • [SOLVED]820-2849 - Charges slowly and cannot start from batteri when under 70%

    I got this MBP 17"

    It turns off when powered from battery and the charge goes below 70%. After this it can only start again when power supply is connected.

    It then starts to slowly charge. It takes long time to get to 100%.

    Tried another battery - same symptoms. Cannot start from battery power only until it reaches around 70%.

    OS X says battery condition is normal
