I've recently noticed that my computer no longer automatically goes to sleep. Fn+F4 still puts it so sleep, but my settings in power manager for this to happen seem to have stopped working. I changed the settings to see if that would help (e.g., turn display off after 1 minute, put computer to sleep after 2 minutes) but to no avail. I'm using the Energystar plan and it doesn't matter if the computer is on battery or plugged in. Anyone have any idea what could be going on?

When this was happening it was not in the ultrabase. When I put it back in the ultrabase this morning it worked properly. Then I took it back out of the ultrabase and it still works properly. Out of curiosity, anyone know what may have been going on? P.S., no peripherals are connected to the ultrabase.
