1–2 Software Guide

Power Management

Using Standby and Hibernation

Standby and Hibernation are energy-saving features that conserve

power and reduce startup time. They can be initiated by you or by

the system.

Standby

Standby in the Microsoft Windows XP and Microsoft

Windows XP Home operating systems reduces power to system

components that are not being used. When Standby is initiated,

your work is saved in RAM (random access memory) and the

screen is cleared. When you exit Standby, your work returns to

the screen where you left off.

Hibernation

Hibernation saves all information in RAM to a hibernation file

on the hard drive, then shuts down the notebook. When you exit

Hibernation, your work returns to the screen where you left off.

If a power-on password is set, the password must be entered to

exit Hibernation.

Hibernation is enabled by default, but can be disabled (usually to

save space on the hard drive). Disabling Hibernation is not

recommended. When Hibernation is disabled, system-initiated

Hibernation cannot save your work if the notebook reaches a

critical low-battery condition while it is on or in Standby.

To verify that Hibernation is enabled, select Start > Control

Panel > Performance and Maintenance > Power Options icon.

Select the Hibernate tab, then ensure that the Enable Hibernation

check box is selected.

Power Management

Software Guide 1–3

Selecting Standby, Hibernation or Shutdown

If you plan to resume shortly—Initiate Standby. Standby clears

the screen, uses less power than leaving the notebook on, and

your work returns instantly to the screen when you exit Standby.

A fully charged new battery pack can support Standby for at least

two days. A battery pack that has been frequently charged and

discharged will support Standby for less time.

If you plan to resume within one week—Initiate Hibernation.

Hibernation clears the screen, saves your work to the hard drive,

and uses much less power than Standby. Returning to work saved

in Hibernation takes longer than returning to work saved in

Standby, but is faster than returning to your place manually after

restarting the notebook. A fully charged battery pack supports

Hibernation indefinitely.

If the notebook will be disconnected from external power for

more than one week—Recharge the battery pack before using it

to run the notebook.

Using Hibernation or Standby While Playing

Media

ÄCAUTION: To prevent possible video degradation and loss of audio

or video playback functionality, do not initiate Standby or

Hibernation while playing media.

If you are playing a medium in an optional drive, turn off the

medium before initiating Standby or Hibernation.

If Standby or Hibernation is accidentally initiated while a

medium is playing:

1. Exit Standby or Hibernation.

2. Restart the notebook.
