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
accessories.toshiba.com. Use only batteries designed to work
with your Toshiba notebook computer.
To ensure that the battery maintains its maximum capacity,
operate the computer on battery power at least once a month.
The Lithium-Ion battery has no memory effect so it is not
necessary to let the battery fully discharge each time.
However, for better accuracy of the battery meter, it is helpful
to fully discharge the battery periodically. Please see
“Maintaining your battery” on page 121 for procedures. If the
computer is continuously operated on AC power, either
through an AC adaptor or a port replicator (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 may cause the battery meter
to be
inaccurate.
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.
