6. Be sure to monitor the remaining battery power. If the battery pack and
real time clock battery discharge completely, Standby Mode will not

adaptor to recharge the batteries.
7. Never install or remove the battery pack without first turning off the
power and disconnecting the AC adaptor. Never remove the battery
pack while the computer is in Standby Mode. Data will be lost.
Note
1. To ensure the battery pack maintains maximum capacity, operate the
computer on battery power once a week until the battery pack is fully
discharged. Refer to the section Extending battery life in this chapter for
procedures. If the computer is continuously operated on AC power for
an extended period, more than a week, the battery might fail to retain a
charge. It might not function efficiently over the expected life of the
battery pack and the Battery indicator might not indicate a low-battery
condition.
2. After the battery pack is charged, avoid leaving the AC adaptor
connected and the computer turned off for more than a few hours at a
time. Continuing to charge a fully-charged battery pack can damage the
battery.
Charging the batteries
The battery pack is classified as a consumable item. The operating life of
the battery pack will gradually reduce through repeated charging and
discharging. It will need to be replaced when it reaches the end of its
operating life.
You must recharge a battery pack when it becomes discharged.
Procedures
To recharge a battery pack while it is installed in the computer, connect the
AC adaptor to the DC IN 15V jack and plug the other end into a working
outlet.

The computer enters Hibernate mode only if Hibernation is enabled in two

TOSHIBA Power Saver.
Use only the computer connected to an AC power source or the optional
TOSHIBA Battery charger to charge the battery pack. Never attempt to
charge the battery pack with any other charger.
