I also have this problem on a Dell Inspiron laptop, Gutsy tribe 2, gnome-power-manager 2.19.5
It shows 5 minutes remaining for approximately 2 minutes, and just keep saying " the discharge time is estimated " after that 2 minutes.
setting apps->gnome-power-manager->use_profile_time to FALSE ( unchecked ) dont't work for me. I tested it with and without rebooting.
