Hello, I have a Dell laptop. Its an Inspiron N4030. Some 8 months ago, my battery gave up completely but I kept using it and now I just bought a new battery and started using it. But then when not plug in, it discharges up to 50 % and then shuts down without any warning and when I plug in and reboot, it charges only up to 80 % and then says Plugged In Not Charging. I even updated my BIOS, changed my battery but still its the same problem.
