The Real Time Clock (RTC) battery provides power for the internal real
time clock and calendar. It also maintains the system configuration.
If the RTC battery becomes completely discharged, the system loses this

will need to set the date and time within the BIOS setup using the following
steps:
1. Press F2 key - the BIOS setup screen will be displayed.
2. Set the date in System Date.
3. Set the time in System Time.

rebooted.
Care and use of the battery pack
The battery pack is a vital component of portable computing. Taking proper
care of it will help ensure longer operating time on battery power as well as
a longer life for your battery pack. Follow the instructions in this section
carefully to ensure safe operation and maximum performance.
The computer's RTC battery is a lithium ion battery and should be replaced
only by your dealer or by a TOSHIBA service representative. The battery
can explode if not properly replaced, used, handled or disposed of.
Dispose of the battery as required by local ordinances or regulations.
You can change the settings of the Real Time Clock by pressing F2 in
POST.
After configuring the time and date for the Real Time Clock battery, we
recommend that you turn the power status of your computer to "ON" so
that the Real Time Clock battery is charged. Refer to Chapter 9
Troubleshooting, for details.
After configuring the date and time it is recommended that you switch the
computer on and then leave it in this state so that the Real Time Clock
battery can be charged.
