Standby, Hibernation and Shutdown Overviews

Standby

CAUTION: To avoid a complete battery discharge, do not leave your

computer in standby for extended periods. Connect the computer to an external power source.

Standby reduces power to system components that are not in use. When standby is initiated, your work is stored in random access memory (RAM), the screen is cleared, and the power lights blink. Saving your work before initiating standby is not usually necessary but is a recommended precaution. When you resume from standby, your work is returned to the screen.

By default, the system initiates standby after 10 minutes of computer inactivity when the computer is running on battery power and after 25 minutes of inactivity when the computer is running on external power. For information about changing these settings, refer to the “

Using Power Schemes”

section later in this chapter.

3–6 Hardware and Software Guide

Hibernation

CAUTION: If the configuration of the computer system is changed during

hibernation, it may not be possible to resume from hibernation. When the computer is in hibernation:

■ Do not connect or disconnect the computer from an expansion

product.

■ Do not add or remove any memory modules.

■ Do not insert remove or replace any hard drives or optical drives.

■ Do not connect or disconnect an external device.

■ Do not insert or remove an external media card such as an

ExpressCard or a Memory Reader card.

Hibernation saves your work to a hibernation file on the hard drive and then shuts down the computer. When hibernation is complete, the power lights are turned off.

When you restore from hibernation, your work is returned to the screen where you left off. If a power-on password has been set, the password must be entered to restore from hibernation. Restoring from hibernation takes a little longer than resuming from standby but is much faster than returning to your place manually after restarting the computer.

Power

Hardware and Software Guide 3–7

Power

To determine whether the computer is in hibernation or turned off, press the power button.

■ If the computer is in hibernation, your work is returned to the

screen.

■ If the computer is off, Windows loads.

When the computer is running on battery power, hibernation is initiated by default after 30 minutes of computer inactivity or whenever the computer reaches a critical low-battery condition.

Hibernation is enabled by default but can be disabled. To prevent loss of work during a critical low-battery condition, disable hibernation only during a battery pack calibration.

To be sure that hibernation is enabled:

» Select Start > Control Panel > Performance and

Maintenance > Power Options > Hibernate tab. If hibernation is enabled, the Enable hibernation check box is selected.

To set the time interval after which the system initiates hibernation:

1. Select Start > Control Panel > Performance and Maintenance > Power Options.

2. Click one of the intervals in the System hibernates list.

Leaving Your Work

If you plan to resume shortly—Initiate standby for shorter times and hibernation for longer times or for power conservation.

The amount of time a battery pack can support standby or hibernation or hold a charge varies by computer configuration and the condition of the battery pack. Standby requires more power than hibernation.

If you plan to resume within 2 weeks—Shut down the computer. If possible, connect the computer to external power to keep an inserted battery pack fully charged.

3–8 Hardware and Software Guide

Power

If the computer will be unused and disconnected from external power for more than 2 weeks—Shut down the computer. To

extend the life of an inserted battery pack, remove the battery pack and store it in a cool, dry location. For information about storing the battery pack, refer to “Storing a Battery Pack,” later in this chapter.

If an external power supply is uncertain (for example, during an electrical storm or low-battery condition)—Take one of the

following actions:

■ Save your work, and then initiate standby.

■ Save your work, and then initiate hibernation.

■ Shut down the computer.

Interference with Drive Media and Bluetooth Communication (Select Models Only)

CAUTION: To prevent the loss of information, possible audio and

video degradation, or loss of audio or video playback quality, do not initiate standby or hibernation while reading or writing to an optical disc.

Standby and hibernation interfere with the use of media and with Bluetooth communication. Note the following guidelines:

■ If the computer is in standby or hibernation, you cannot

initiate a Bluetooth transmission.

■ If standby or hibernation is initiated while a drive medium

such as a CD or DVD is in use

❏ Your playback may be interrupted.

❏ You may see the warning message “Putting the computer

into hibernation or standby may stop the playback. Do you want to continue?” If the message is displayed, click No.
