Power Management Options in Windows Vista®

The Windows Vista power management features are designed to reduce the amount of electricity your computer uses when it is on and you are not using it. You can reduce power to just the monitor or the hard drive, and Windows Vista sets the default "off" state to standby mode or you can set hibernate mode to reduce power even further.
