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 and the BIOS setup utility.
(See BIOS Setup
Utility on page 27 for more information)
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 and BIOS setup utility.
(See BIOS
Setup Utility on page 27 for more information)
WINDOWS POWER MANAGEMENT
The Power Options icon located in the Windows
Control Panel allows you to configure some of the power
management settings. For example, you can use the
Power Management to set the timeout values for turning
off the display and hard disks whether you are running
the LifeBook notebook on battery power or one of the
adapters.
(See Pre-Installed Software on page 97 for more
information)
The settings may also be changed in the
BIOS.
(See BIOS Setup Utility on page 27 for more infor-
mation)
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.
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.
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.
■
If your LifeBook 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 Hiberna-
tion (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 periph-
eral devices will be re-initialized when
the system restarts.
■
The main advantage of using the
Hibernation (Save-to-Disk) function is
that power is not required to maintain
your data. This is particularly impor-
tant if you will be leaving your Life-
Book notebook in a suspended state
for a prolonged period of time. The
drawback of using Hibernation (Save-
to-Disk) mode is that it lengthens the
power down and power up sequences
and resets peripheral devices.
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.
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.
