Running the computer on battery power
The computer contains a removable Li-ion high-capacity
battery that provides power when you are away from an AC
outlet. You can recharge it many times.

Battery Notice

To ensure that the battery maintains its maximum capacity,
operate the computer on battery power at least once a month
until the battery is fully discharged. Please see “Maximizing
battery life” on page 96 for procedures. If the computer is
continuously operated on AC power, either through an AC
adapter or a docking station (if applicable to your system), for
an extended period (more than a month) the battery may fail
to retain a charge. This may shorten the life of the battery, and
the battery light may not indicate a low-battery condition.
In addition, the computer has an internal real-time clock
(RTC) battery. The RTC battery powers the RTC memory,
which stores your system configuration settings and the
current time and date for up to a month while the computer is
turned off.
NOTE: For optimum DVD performance, Toshiba recommends that
you play DVDs while running on AC power rather than on battery
power.

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.
