Get TuneUp Utilities 2010, it has a turbo mode which you can one-click enable and it will disable the aero theme as well as a lot of the unwanted processes. It's for giving your computer more juice while gaming but it's good for battery life too.
lolz yea that's the only bad thing about it, it's a great little program and has some awesome features, but the fact that there's a price tag on it suxors.
