About High Temperature 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 the [Main] menu of the Setup Utility
to [High Temperature]. Note that a level of 100% in the [High Temperature] mode is
about a level of 80% in the [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.
Plug in the AC adaptor, and fully charge your battery.
Use a spare battery if you have one.
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.
Save your data and power off your computer

When the Remaining Battery Charge Becomes Low
The computer can be set to notify of a low battery level, etc. using the following
menu. 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
[Control Panel] - [Power Options] - [Alarms]
Windows XP
[Control Panel] - [Performance and Maintenance] - [Power Options] - [Alarms]
Set the value for the [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 pro-
gram 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 con-
necting the AC adaptor. If the computer starts up or resumes while the AC adaptor
is not connected, Windows may not operate properly or alarm operations may
stop working.
When disabling the speakers with the Setup Utility (or pressing Fn + F4 ), the
alarm beep is also disabled.
