Battery Wont Charge


Sep 11, 2017
I bought a Lenovo G50-70 laptop April 2016 and the battery has been working perfectly well until Thursday, September 7, 2017. On the evening of Thursday, September 7, 2017 i left it charging for about 4 hours because it was low on battery. When i woke up on Friday, September 8, 2017, the laptop won't work unplugged at all and the battery won't charge (Even though OS detects the battery correctly and says "plugged in, charging". I have removed the battery and adapter and pressed the power for 3-4 seconds, but the laptop won't run unless plugged on power. What could be the problem?
