Power Management Modes

Standby and Sleep Mode

Standby mode (sleep mode in Microsoft Windows Vista) conserves power by turning off the display and the hard drive after a predetermined period of inactivity (a time-out). When the computer exits standby or sleep mode, it returns to the same operating state it was in before entering standby or sleep mode.

NOTICE: If your computer loses AC and battery power while in standby or sleep mode, it may lose data.

To enter standby mode in Windows XP, click the Start button, click Turn off computer, and then click Stand by.

To enter sleep mode in Windows Vista, click the Windows Vista Start button, , and move your mouse over the right triangle beside the lock option to

open the Power Options Properties window, and then click Sleep.

Depending on how you set the power management options in the Power Options Properties window or the QuickSet Power Management Wizard, you may also use one of the following methods:

•Press the power button.

•Close the display.

•Press <Fn><Esc>.

To exit standby or sleep mode, press the power button or open the display, depending on how you set the power management options. You cannot make the computer exit standby or sleep mode by pressing a key or touching the touch pad or track stick.

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 hibernate mode, it returns to the same operating state it was in before entering hibernate mode.
