Power Management

Selecting a Power Source

Any supported power source can be used to work in most software applications, but some tasks require the specific power sources described in the following table.

Task Powe r Sou r c e

Charge or calibrate a primary or external battery pack.

Install or modify system software.

■

Charged battery pack in the notebook.

■

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.

1–2 Software Guide

Power Management

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

CAUTION: 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.

Power Management

Identifying a Critical Low-Battery Condition

If a low-battery condition is not resolved, the notebook enters a critical low-battery condition. In a critical low-battery condition:

■

If Hibernation is enabled and the notebook is on or in Standby, the notebook then initiates Hibernation.

■

If Hibernation is disabled and the notebook is on or in Standby, the power/standby light blinks. The notebook remains briefly in Standby, then shuts down and your unsaved work is lost.

Hibernation is enabled by default. To verify that Hibernation is

■

Connect the notebook to an electrical outlet.

■

Plug an optional Automobile Power Adapter/Charger into the notebook and into a vehicle cigarette lighter receptacle.

■

Plug an optional Aircraft Power Adapter into the notebook and into the in-seat power supply available on some commercial aircraft. (An Aircraft Power Adapter can run the notebook but cannot charge a battery pack.)

When a Charged Battery Pack Is Available

Turn off the notebook or initiate Hibernation, then insert a charged battery pack. For instructions, see the Hardware Guide, Chapter 3, “Battery Pack,” on this CD.

When No Power Source Is Available
