Running the computer on battery power
For optimum optical media performance, it is recommended that you
play DVDs while running the computer on AC power. For more
information about Windows® power plans, see “Power Plans” on
page 81.
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.
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
Customer Support Center.
Charging the main battery
The battery needs to be charged before you can use it to power the
computer.
To charge the main battery, plug the computer into a live electrical
outlet. The battery charges whether the computer is on or off.
TECHNICAL NOTE: The recharging of the battery cannot occur when
your computer is using all of the power provided by the AC adaptor to
run applications, features, and devices. Your computer's Power Options
utility can be used to select a power level setting that reduces the power
required for system operation and will allow the battery to recharge.
