Normally I'm answering questions here, but today I'm asking.
Today, my laptop (Dell Latitude D620) suddenly claimed that the battery was "not present". This occurs both under Ubuntu Linux (Feisty 7.04) and in the system BIOS. It's obviously not strictly a Linux problem, but I'm hoping someone else has seen something similar. The battery light comes on (green, as if charging) when the battery is plugged in and goes off when the battery is removed.
I've tried removing and reinserting the battery both with the system on and off. I don't have an identical system to try changing batteries with, unfortunately.
Any thoughts would be GREATLY appreciated.
