Running the computer on battery power
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 included with your computer or visit the Toshiba Web
site at accessories.toshiba.com. Use only batteries designed to work
with your Toshiba 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 51 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.
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.
Monitoring main battery power
The computer’s main battery light gives you an indication of the
main battery’s current charge. The following also applies to the
secondary battery (available on certain models) if installed.
❖
Glows amber while the main battery is being charged
(AC adaptor connected)
❖
Glows white when the main battery is fully charged
