Previously, I wrote about PowerSlave and BattCursor tool for laptop battery. Here is one more extremely useful tool Aerofoil which helps you to extend & improve Laptop battery life when you are using Windows Vista or Windows 7 as your OS.

Aerofoil is a small tray utility for Windows Vista and Windows 7 to automatically disable the Windows Aero Glass interface, and optionally switch Windows Power Plans, Windows Sidebar and sound off when your notebook computer runs on battery.

Aero Glass is re-enabled on program exit or whenever it is connected to the AC power again. In addition it also provides other useful features such as a quick hibernate shutdown option and manual control of Aero Glass.

Aerofoil will also show whether your system is on battery or AC by the color of the tray icon it has, red is battery and green is AC.
