Power
Understanding Standby and Hibernation
Standby and Hibernation are energy-saving features that conserve
power and reduce startup time. In general, Hibernation shuts
down most notebook functions, while Standby simply reduces
notebook activity. Standby uses more power than Hibernation, but
you can resume more quickly from Standby.
■Standby reduces power to system components that are not in
use. When Standby is initiated, your work is saved in random
access memory (RAM) and the screen is cleared. When you
resume from Standby, your work returns to the screen where
you left off.
■Hibernation saves system memory to the hard drive, takes a
snapshot of the notebook image, and shuts down the
notebook. When you resume from Hibernation, your work
returns to the screen exactly as you left it.
1
When possible, save your work before initiating Hibernation to
prevent loss of data. Do not change the notebook configuration
during Hibernation.
CAUTION: If the configuration of the notebook system is changed during
Hibernation, resumption from Hibernation may not be possible. When the
Ä
notebook is in Hibernation:
■Do not add or remove memory modules.
■Do not connect or disconnect external devices.
■Do not insert or remove CDs or DVDs.
■Do not insert or remove a CardBus PC Card.
Software Guide1–1
Power
If you cannot resume from Hibernation when power is restored to
the system, you are prompted to delete the restoration data and
proceed with system boot. Unsaved data is lost.
If you have assigned a start-up function to a password set in the
Setup utility, that password must be entered to resume from
Hibernation.
Enabling or Disabling Hibernation
CAUTION: If Hibernation is disabled, the system cannot save the
Ä
system memory if the notebook reaches a critical low-battery
condition. (For information about low-battery conditions, refer to the
“Battery Packs” chapter in the
Hibernation is enabled by default. Compaq recommends that you
use the notebook with Hibernation disabled only while you are
calibrating a battery pack. For calibration information, refer to the
“Battery Packs” chapter in the Hardware Guide on this CD.
To verify that Hibernation is enabled, select Start > Control
Panel > Performance and Maintenance > Power Options icon >
Hibernate tab. If Hibernation is enabled, the Enable Hibernation
check box is selected.

1–2Software Guide
Choosing Standby, Hibernation or
Shutdown
When You Leave Your Work
The amount of time a battery pack can support Standby or
Hibernation or hold a charge varies by notebook configuration
and the condition of the battery pack.
If you plan to resume shortly: Initiate Standby for shorter times
and Hibernation for longer times or power conservation.
■Initiating Standby clears the screen, uses less power than
leaving the notebook on, and your work returns quickly to the
screen when you resume from Standby.
■Initiating 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.
Power
If you plan to resume within 2 weeks: Shut down the notebook. If
possible, connect the notebook to external power to keep the
battery pack fully charged.
If the notebook will be disconnected from external power for more
than 2 weeks: To extend the life of the battery pack, shut down
the notebook and remove and store the battery pack. For
information about removing and storing a battery pack, refer to
the “Battery Packs” chapter in the Hardware Guide on this CD.
When the Power Supply Is Uncertain
Verify that Hibernation is enabled: Select Start > Control Panel >
Performance and Maintenance > Power Options icon > Hibernate
tab. If Hibernation is enabled, the Enable Hibernation check box
is selected.
Software Guide1–3
Power
If the battery pack reaches a critical low-battery condition (one
percent of a full charge) while Hibernation is enabled, the system
initiates Hibernation, saves the system memory to the hard drive,
then shuts down the notebook. If the battery pack reaches a
critical low-battery condition while Hibernation is disabled, the
notebook cannot save the system memory.
If the notebook is running on external power, power may be
interrupted by an uncertain power supply or an electrical storm. If
you pause your work when the power supply is uncertain,
Compaq recommends that you save your work, then initiate
Hibernation or shut down the notebook.
When Using Infrared or Drive Media
CAUTION: Initiating Standby or Hibernation while playing a drive
Ä
medium may stop the play or diminish the quality of the play.
Standby and Hibernation interfere with the use of infrared
communication and drive media.
■If the notebook is in Standby or Hibernation, you cannot
initiate an infrared transmission.
■If Standby or Hibernation is accidentally initiated while a
drive medium is in use:
❏If you see the warning message “Putting the computer
into Hibernation or Standby may stop the playback. Do
you want to continue?” select No. (Audio and video may
resume or you may need to restart the drive medium.)
❏If Standby or Hibernation initiates and no warning
message is displayed, resume from Standby or
Hibernation by briefly pressing the power button.
