Touch Pad
Do not place any object on the work surface or press down forcefully with sharp-
pointed objects (e.g.nails) or hard objects that can leave marks (e.g.pencils and
ball point pens).
Try to avoid having any harmful substances, such as oil, come in contact with the
touch pad. The cursor may not work properly in such cases.
When the touch pad becomes dirty:
Wipe to remove dirt by using a dry soft cloth such as gauze or a soft cloth first
applied with detergent diluted with water and then thoroughly wrung.
Do not use benzene or thinner, or rubbing alcohol. Doing so may adversely affect
the surface, e.g., discoloration. In addition, do not use commercially-available
household cleaners and cosmetics, as they may contain components harmful to
the surface.

Standby/Hibernation Functions
Starting UpYour Computer Quickly
We recommend plugging in the AC adaptor if the standby function is to be
used for a long period of time. If the AC adaptor cannot be connected, we
recommend that hibernation mode be used instead of the standby mode.
If the standby or hibernation function is used repeatedly, the computer may
not work properly.To stabilize computer operations, we recommend shutting
down Windows on a regular basis (about once a week) without using the
standby or hibernation function.
NOTE
Use any of the following methods to enter the standby or hibernation mode.
To use the hibernation mode, make the setting below in advance. (Enabled in factory
preset.)
Fn key combinations ( page 3)
Using the power switch ( page 10)

Standby/Hibernation Functions
Precautions
Before entering the standby or hibernation mode
Save all data.
When a file in an external device such as a CD drive, external hard disk, or ATA
card is opened, close the file.
Even when a password has been set in the Setup Utility, [Enter Password] does
not appear when the computer resumes from the standby or hibernation mode.
If you want to use the security function when using the standby or hibernation
mode, use the Windows password as follows:
Windows 2000
1Set the password in [Control Panel] - [Users and Passwords].
2Add the check mark for [Prompt for password when computer goes off standby]
in [Control Panel] - [Power Options] - [Advanced].
Windows XP
1Select the account to change in [Control Panel] - [User Accounts].
2Set the password.
3Add the check mark for [Prompt for password when computer resumes from
standby] in [Control Panel] - [Performance and Maintenance] - [Power Options]
- [Advanced].
Do not enter either the standby or hibernation mode under the following condi-
tions. You may corrupt your data or file, the standby or hibernation function may
not work, or the computer (or peripherals) may fail to work properly.
• When the floppy disk drive indicator ( ), hard disk drive indicator ( ), CD drive
indicator ( ) or access lamp on the CD drive is on ( page 5).
• When playing/recording audio files and displaying images (such as MPEG files).
• When using the communications software and the network function.
• When using LAN port (cards), SCSI cards and modem port (cards) etc. (If these
cards fail to work properly, restart the computer.)
When entering the standby or hibernation mode*
Avoid the following:
•Touching the keyboard, pointing device (touch pad, external mouse, etc.), or
power switch.
• Connecting or disconnecting the AC adaptor.
• Closing or opening the display.
* Standby mode: until the power indicator blinks green
Hibernation mode: until the power indicator goes off
In standby or hibernation mode
Do not insert or remove peripherals; abnormal operation may result.
In standby mode, power is consumed. If PC Cards are inserted, more of that
power is consumed. When all power has been consumed, all data saved at standby
is lost since it is retained in memory. We therefore recommend plugging in the AC
adaptor when using the standby function.

10
Standby/Hibernation Functions
Press the power switch; at the “beep*”sound, re-
lease your finger
The computer will enter either the standby or hibernation mode,
depending on the setting.
After releasing your finger from the power switch, do not touch the power switch
until the power indicator goes off or blinks.
At the “beep*” sound, release your finger from the power switch. If you con-
tinue to press down on the switch and hold it for more than four seconds, the
unit will emit a second “beep*” then power off. Data not previously saved will
be lost.
Windows 2000
Even when [When I press the power button on my computer] is set to [Power
Off] with [Start] - [Settings] - [Control Panel] - [Power Options] - [Advanced], if
you press the power switch for more than four seconds and do not release it, a
second“beep*” will sound and the computer will be turned off forcibly. Data not
previously saved will be lost.

Remaining Battery Level Confirmation by Alarm
The computer can be set to notify of a low battery level, etc. using the following proce-
dure. When the battery level goes down to the level specified, the computer sets off an
alarm and displays a message indicating the low battery level.
Windows 2000
[Start] - [Settings] - [Control Panel] - [Power Options] - [Alarms]
Windows XP
[start] - [Control Panel] - [Performance and Maintenance] - [Power Options] - [Alarms]
Set the value for [Critical battery alarm] to 5% or more. This is necessary for the
standby or hibernation function to be completed (assuring data is saved) when the
battery level is low.
When making a setting for [When the alarm goes off, the computer will:] in [Alarms]-
[Alarm Action], add a check mark for [Force standby or shutdown even if a program
stops responding.].
If the computer shuts down or enters the standby or hibernation mode by the Alarm
settings function, start up the computer or resume operations after connecting the
AC adaptor. If the computer starts up or resumes while the AC adaptor is not con-
nected, Windows may not operate properly or alarm operations may stop working.
When disabling the speakers with pressing Fn + F4 , the sound alarm is also
disabled.
When the Remaining Battery Charge Becomes Low
Save your data and power off your computer
Then:Plug in the AC adaptor, and fully charge your battery.

In the standby mode, do not remove/change the battery pack.
If you have neither the AC adaptor nor an extra battery, power the computer off.
About HighTemperature Mode
This computer has a high temperature mode function that prevents the degradation of
the battery in high temperature environments.
We recommend setting the high temperature mode function when installing the com-
puter in a car, etc.To do this, set [Environment] in [Main] menu of the Setup Utility to
[High Temperature].Note that a 100% remaining battery reading in [High Temperature]
mode is about an 80% reading in [Normal Temperature] mode.
After switching from [Normal Temperature] to [High Temperature], or vice versa, the
remaining battery will not be displayed properly until the battery pack is completely
discharged or fully charged.
