    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...

                          by unnu
                          i have a lenovo ideapad y560 laptop , the laptop was working fine till i decided to upgrade its bios from downloaded setup file found on lenovo website.
                          the laptop bios updated perfectly but then it started having booting problems like blinking cursor , or a few other hang ups at bootup time .
                          i read somewhere on the lenovo website that the bios can be downgraded using the same program used to update the bios. so i downgraded the bios and the laptop screen went dark black blank when it was supposed to reboot into windows. i had to remove its battery and charger adapter cable to shut...

                          by ahmarzo
                          I have acer laptop tmx314-51 with part no 6050A3020501.
                          The laptop is working fine on adapter and battery is also charging and when adapter is disconnected in on state the laptop gives backup on battery and gives good backup.
                          But when laptop is powered on through battery only the laptop does not power on and there is 0 voltage on battery connector.
                          I have not not tried another battery as it is not available locally could this be a battery problem.have checked discharging mosfet and there is no shorting to ground on any pin of battery connector.
                          The schematic is not available...
