    Carefully measure the voltage to ground of each pin on the battery connector.

    Post each measurement.

      I removed the battery and tried to turn on the laptop without it but now the voltages in all the board not normal, 3 and 5 volts appear for one second then lost for another one second, it keeps doing that (appear-disappear) while I use adapter, also battery connector voltage appear for one second and keep doing same. I tried another charger, but it's still doing the same.

        I did that without connecting the battery.
