In addition to the main battery, you may also have a second
battery installed in the Slim SelectBay. 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's
Slim SelectBay, or carry additional charged battery packs
with you.
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.
Running the computer on battery power
TECHNICAL NOTE: The RTC battery does not charge while the
computer is turned off, even when AC power is attached.
The RTC battery charges when the computer is powered 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 Global Support Centre.
