    Solved! Laptop turns off suddenly

    I have a Lenovo G40-70, i5 4th gen, 12 GB RAM. After 3 months of use, it started turning off while on battery with no warning notification or sound. I can't even use it for 20 minutes max. The battery might read 50%-90% and suddenly is drained to 0% and turns off. I don't think it shuts down...
