I have a Lenovo G50 model 20351. I've had it since late august. So far, it's been great, but today I tried charging it since the day started (I plugged it at 7 am, now it's 4:30 pm) and it's been 13% since then. It's been in charge since I got home too! I removed it a little and even restarted, nothing happened. What can I do to fix this?
