It shows I have 30 minutes left. The update involved kernels. I just don't know. I don't know if I'll have power or not in a half hour. Is there any way to roll back changes. What to do?

I have had this issue for some time now. With Ubuntu running, my battery would not charge. I could leave it running and plugged in for hours. Then, when I pull the plug, it complains about the battery being low. If I leave it plugged in while the power is off it would charge just fine.
Recently, I installed Fedora for a time. I never noticed any issues with charging while the OS was running. I just upgraded to Ubuntu 11.10, and I am noticing the same issue again. Yesterday, the battery sat at 83% while I left it on. It didn't start charging until I rebooted.
On older versions of Ubuntu, my solution was to start "upower". I learned that if I put the "upower" command in the startup applications, that I wouldn't have the issue. I haven't spent enough time on it with Ubuntu 11.10 yet to see if that works. I would love to get this fixed though so I don't need a work around.
