Running the computer on battery power

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, see your accessories information that shipped with your
computer or 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
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. 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.
Using additional batteries
If you spend a lot of time traveling and need to work for
many hours without an AC power source, you may want to
carry additional charged batteries with you. You can then
replace a discharged battery and continue working.
Battery safety precautions
Turn off the computer’s power immediately and
disconnect the power cable from the power socket, if the
battery produces an odor, overheats or changes color or
shape while it is being used or charged. Carefully remove
the battery from the computer.
