Lately I have been experiencing an annoying behavior from Gnome. I am on my laptops battery fairly often being a student, so going into powersave mode and the like is a must. This normally isn’t a problem and basically just works when I plug into/out of AC power.

In the past few weeks, however, I have been getting problems from Gnome. I will unplug the AC power and Gnome won’t recognize it and won’t adjust all my settings to conserve power. Sometimes after a few minutes Gnome will realize it, but there have been occurrences where I have drained the entire battery flat and it still believed it was plugged in. Sometimes suspend/resuming will cause it to realize it is in battery mode but not always.

So far I have not found a solution for this or an absolute way to poke Gnome to realize it’s on battery power. I’m hoping it will just magically fix itself in the next few days.
