Comment 27 for bug 393008

This problem is intermittent on my Dell Studio 1537. The command "cat /proc/acpi/battery/BAT0/state" always seems to show correctly whether the AC adapter is present, but the gnome-power-manager in the panel and the output of devkit-power --dump always says the AC adapter is connected.

When I check the power history is shows the laptop battery with the refreshed attribute set to 55876 seconds. Not sure what that is, but if that is how often gnome-power-manager checks for the ac adapter it could be part of the problem.
