Hardware and Software Guide 3–7
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.
ÄCAUTION: To reduce the risk of information loss, save your work 
before initiating hibernation.
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.
Determining Whether the Computer Is Off 
or
 in Hibernation
To determine whether the computer is turned off or in 
hibernation, press the power button.
■If the computer is in hibernation, the computer restores from 
hibernation and your work is returned to the screen.
■If the computer is off, Windows loads.

Enabling or Disabling Hibernation
Hibernation is enabled by default but can be disabled. To prevent 
loss of work when the computer is in Windows and reaches 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 icon
 > 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 are working in Windows and 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 
from Windows. If possible, connect the computer to external 
power to keep an inserted battery pack fully charged.  
						

							Powe r
Hardware and Software Guide 3–9
If the computer will be unused and disconnected from external 
power for more than 2 weeks—Shut down the computer from 
Windows. 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 the “
Storing a 
Battery Pack” section 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)
ÄCAUTION: 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 Bluetooth 
communication and media. 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 might stop the playback. Do 
you want to continue?” If this message is displayed, 
click
 No. 
❏You may need to restart the disc to resume audio and 
video playback.
