Remaining Battery Level Confirmation by Alarm
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 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 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.
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.
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 100% remaining battery reading in the [High Tempera-
ture] mode is about an 80% reading 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.
