system's battery life under any conditions other than the specific
test settings.
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 31 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.
Monitoring battery power
The computer's battery light gives you an indication of the battery's
current charge.
❖ Glows amber while the battery is being charged
(AC adaptor connected)
❖ Glows white when the battery is fully charged
❖ Is unlit when the battery has discharged, the battery is not
charging, or the AC adaptor is not plugged into the computer or
AC outlet
❖ Flashes amber when the battery charge is low and it is time to
recharge the battery or plug in the AC adaptor
TECHNICAL NOTE: Depending on your system, the RTC battery may
only charge while the computer is turned on.
Battery life and charge time may vary, depending upon power
management settings, applications and features used.
