Running the computer on battery power
NOTE
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.
Power management
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.
Using additional batteries
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.
For more information on batteries and accessories, see
accessories.toshiba.com.
Charging the main battery
The battery needs to be charged before you can use it to power the
computer.
For optimum optical media performance, it is recommended that you
play DVDs while running the computer on AC power. For more

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