    problem with a laptop lenovo g50-70

    hello everyone,
    i have a problem with a laptop lenovo g50-70
    the laptop charges the battery when it is powered off. when i turn it on it will drain from the battery till it finishes and then shuts off. if i try to turn it on without the battery it will turn for 2 seconds and then will turn off again
    any suggestions ?

        here is the schematics.. trace the voltage from the battery maybe a shorted mosfet or open fusible resistor.. happy hunting...
