Battery Notice
Battery life may vary considerably from specifications
depending on product model, configuration, applications,
power management settings and features utilized, as well as
the natural performance variations produced by the design of
individual components. Published battery life numbers are
achieved on select models and configurations tested by
Toshiba at the time of publication. Recharge time varies
depending on usage. 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, see the accessories information that shipped with your
computer or visit the Toshiba Web site at
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
for procedures. If the computer is
continuously operated on AC power, either through an AC
adaptor 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.
For optimum DVD performance, it is recommended that you
play DVDs while running the computer on AC power. In
addition, your computer’s Power Saver utility can be used to
select a power level setting for DVD playback.
The computer also has an internal real-time-clock (RTC)
battery.
