Overview

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, the
Windows desktop is restored to the state it was in before it entered 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:
Depending on your operating system, the procedures to activate the standby and hibernate
modes may be different.
Standby Mode
Standby mode conserves power by turning off the display and the hard drive after a time-out.
When the computer exits from standby mode, it returns to the operating state it was in before it
entered standby mode.
To set standby mode to automatically activate after a defined period of inactivity:
1 Click the Start button and click Control Panel.
2 Under Pick a category, click Performance and Maintenance.
3 Under or pick a Control Panel icon, click Power Options.
To immediately activate standby mode without a period of inactivity, click the Start button,
click Turn Off Computer, and then click Stand by.
To exit from standby mode, press a key on the keyboard or move the mouse.
NOTICE:
If your computer loses power while in standby mode, it may lose data.
Hibernate Mode
Hibernate mode conserves power by copying system data to a reserved area on the hard drive
and then completely turning off the computer. When the computer exits from hibernate mode,
the desktop is restored to the state it was in
before it entered hibernate mode.
To activate hibernate mode:
1 Click the Start button and click Control Panel.
2 Under Pick a category, click Performance and Maintenance.
3 Under or pick a Control Panel icon, click Power Options.
4 Define your hibernate settings on the Power Schemes tab, Advanced tab, and Hibernate tab.
