The computer also has an internal real-time-clock (RTC) battery.

The RTC battery powers the RTC memory that stores your system 
configuration settings and the current time and date information. It 
maintains this information for up to a month while the computer is 
turned off.

TECHNICAL NOTE: Depending on your system, the RTC battery may 
only charge while the computer is turned on.

Your computer ships with the power management options preset 
to a configuration that will provide the most stable operating 
environment and optimum system performance for both AC power 
and battery modes.

Changes to these settings may result in system performance or 
stability issues. Users who are not completely familiar with the power 
management component of the system should use the preset 
configuration. For assistance with setup changes, contact Toshiba’s 
Customer Support Center.

If you travel and need to work for many hours without an AC power 
source, you may purchase a battery module for use in the computer, 
or carry additional charged battery packs with you. You can then 
replace a discharged battery and continue working.
