Mobile Computing
Running the computer on battery power
5.375 x 8.375 ver 2.3.2
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: 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.
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.
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.
Using additional batteries
In addition to the main battery, you may also have an optional
second battery (not included with your computer). 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.
