There are few things more frustrating than running out of juice on
your laptop on a cross-country flight, or at your favorite cafe.
This program promises to help put an end to those frustrations. It
automatically deactivates Windows Aero and the Windows Sidebar when
your laptop runs on battery power, which the author claims will
extend battery life. You can also have the program automatically
turn off Aero or the Sidebar when your batter level drops below a
limit that you set.
