Comment 13 for bug 120258

I have the same problem appear suddenly on my Dell 1420. The battery manager does not work correctly any longer. If I run the laptop on battery power, it will not charge after I plug it back in. Once plugged-in, it says I am fully charged at some percentage (which drops each time I unplug). If I reboot and go to to the bios, I can watch the battery charge as normal. I first thought it was a battery problem. Dell sent me a new battery. Same problem. I first noticed this defect about two weeks ago. So it may not be related to the original issue in this thread.
