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 by going to the Control Panel and navigating
to the Power Options Properties window. From the
Power Schemes tab, you can select the amount of time
for the monitor to stay on.
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 by going to the Control Panel and navigating
to the Power Options Properties window. From the
Power Schemes tab, you can select the amount of time
for the hard disk to stay active.

WINDOWS POWER MANAGEMENT
The Power Options icon in the Control Panel allows you
to configure some of the power management settings. As
noted above, you can use the Power Options 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. This utility also offers several
other methods for optimizing battery life.
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/CD Access
indicator is off. (See figure 2-8 on page 14) If you turn off
the power while accessing a disk there is a risk of data
loss. To ensure that your LifeBook notebook shuts down
without error, use the Windows shutdown procedure.
Never turn your notebook off while an
application is running. Be sure to close all
files, exit all applications, and shut down
your operating system before turning off
power. If files are open when you turn the
power off, you will lose any unsaved
changes, 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.
