Freeware utility
Vista Battery Saver extends how long you can use your Vista laptop between charges by killing a couple of Vista's unnecessary energy hogs when you unplug your laptop, namely Aero (Vista's fancy new interface) and the Windows Sidebar. Plug your computer back in and these features are automatically re-enabled. It's unclear how much battery life this will save (the Windows Vista blog suggests as little as 1-4%), but if you need to squeeze out every last unplugged minute you can, this could be a lifesaver.

This is BETA software!, please use caution when installing it on your system
