If your laptop seems to be running hot lately, and it's eating lots of battery power, you might have some old cpufreq settings for gnome-power-manager in gconf. You can reset them to their (new) default values by running the following commands:
gconftool-2 -u /apps/gnome-power-manager/cpufreq_ac_policy gconftool-2 -u /apps/gnome-power-manager/cpufreq_battery_policy
This brought the temperature of my laptop down, so the fan isn't running all day anymore, and as a side-effect, my battery doesn't give up after an hour anymore after an hour of doing almost nothing (I get the proper 2-3 hours out of it now).
