I'm using lenovo p770 it had improper charging problem.i don't know why?

I brought lenovo p770 before 6 months.now. I got a problem that my mobile is charging. But percentage does not increasing. Now what is the problem and how should i solve it?

There's definitely your battery's problem its dead now. If your pc is still in warranty just go and replace it, otherwise there's only 6 months warranty on battery.
