Running the computer on battery power
The computer contains a removable Lithium Ion (Li-Ion)
high-capacity battery that provides power when you are away
from an AC outlet. You can recharge it many times.
Battery Notice
Battery life may vary depending on applications, power
management settings and features utilized. Recharge time varies
depending on usage. The battery may not charge while the
computer is consuming full power.
After a period of time, the battery will lose its ability to
perform at maximum capacity and will need to be replaced.
This is normal for all batteries. To purchase a new battery
pack, visit the Toshiba Web site at:
toshiba.com.
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 126 for procedures. If the computer is
continuously operated on AC power, either through an AC
adapter or a docking station for an extended period, more
than a month, the battery may fail to retain a charge. It may
not function efficiently over the expected 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.
For optimum DVD performance, Toshiba recommends that you
play DVDs while running on AC power rather than on battery
power.
