I have an HP pavilion g6 laptop with Ubuntu 13.04 installed. Recently I installed jupitor for ubuntu 13.04 and uninstalled in due to some issues. I don't know whether it is the reason but now my battery indicator in ubuntu has gone crazy. When I plugged my laptop in, it indicates that the battery is low with red battery icon. When I unplugged, it shows battery is charging. I previously looked at this question but no answer found for my case. Can anybody give me a solution.
