■
If your notebook is actively accessing
information when you enter the Suspend
or Hibernation (Save-to-Disk) modes
changes to open files are not lost. The
files are left open and memory is kept
active during Suspend mode or the
memory is transferred to the internal
hard drive during Hibernation (Save-to-
Disk) mode.
■
When PC Cards or external devices are
in use, Save-to-Disk mode cannot return
to the exact state prior to suspension,
because all of the peripheral devices are
re-initialized when the system restarts.
■
The main advantage of using Hiberna-
tion is that power is not required to
maintain your data. This is important if
you will be leaving your notebook in a
suspended state for a prolonged period
of time. The drawback of using Hiberna-
tion mode is that it lengthens the power
down and power up sequences and
resets peripheral devices.
DISPLAY TIMEOUT
The Video Timeout is one of the power management
parameters. This feature saves power by turning off the
display if there is no keyboard or pointer activity for the
user selected timeout period. Any keyboard or pointer
activity will cause the display to restart automatically.
This feature is independent of the Power/Suspend/
Resume button and can be enabled and disabled in
Windows.
HARD DISK TIMEOUT
The Hard Disk Timeout is another one of the power
management parameters. This feature saves power by
turning off the hard drive if there is no hard drive
activity for the user selected timeout period. Any
attempt to access the hard drive will cause it to restart
automatically. This feature is independent of the Power/
Suspend/Resume button and can be enabled and
disabled in Windows.
WINDOWS POWER MANAGEMENT
The Power Options icon in the Windows Control Panel
allows you to configure some of the power management
settings. For example, you can use the Power Manage-
ment to set the timeout values for turning off the display
and hard disks whether you are running the notebook
on battery power or one of the adapters. (See Pre-
Installed Software on page 85 for more information)

RESTARTING THE SYSTEM
If your system is on and you need to restart it, be sure
that you use the following procedure.
1. Click the Start button, and then click Shut Down.
2. Select the Restart option from within the Windows
Shut Down dialog box.
3. Click OK to restart your LifeBook notebook. Your
notebook will shut down and then reboot.
Turning off your LifeBook notebook
without exiting Windows or turning on
your notebook within 10 seconds of the
notebook being shut off may cause an
error when you start the next time.
POWER OFF
Before turning off the power by choosing Shut Down
from Windows, check that the Hard Drive, optical drive,
PC Card and Floppy Disk Drive Access indicators are all
Off. (See figure 2-8 on page 13) If you turn off the power
while accessing a disk or PC Card there is a risk of data
loss. To ensure that your LifeBook notebook shuts down
without error, use the Windows shut down procedure.
Never turn your LifeBook notebook off
while an application is running. Be sure to
close all files, exit all applications, and shut
down your operating system prior to turn-
ing off the power. If files are open when
you turn the power off, you will lose any
changes that have not been saved, and
may cause disk errors.
Using the correct procedure to shut down from Windows,
allows your LifeBook notebook to complete its operations
and turn off power in the proper sequence to avoid errors.
The proper sequence is:
1. Click the Start button, and then click Shut Down.
2. Select the Shut Down option from within the
Windows Shut Down dialog box.
3. Click OK to shut down your LifeBook notebook.
If you are going to store your LifeBook notebook for a
month or more, see the Care and Maintenance section of
this manual.
