Power Management
Overview
The Microsoft
®
Windows

XP power management features can 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, or you can use standby mode or hibernate mode to reduce power to the entire computer.
When the computer exits from a power conservation mode, it returns to the operating state it was in
prior to entering the mode.
NOTE: Windows XP Professional includes security and networking features not available in Windows XP Home
Edition. When a Windows XP Professional computer is connected to a network, different options related to security
and networking appear in certain windows.
NOTE: The procedures to activate the standby and hibernate modes may vary according to your operating system.
