Power and Power-Up Modes
To ensure that the battery pack maintains its maximum capacity, operate
the computer on battery power at least once a month until the battery pack
is fully discharged. Refer to Extending battery life in this chapter for
procedures. If the computer is continuously operated on AC power through
an AC adaptor 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 indicator may not indicate a low-battery
condition.
High Capacity 2nd Battery Pack
A High Capacity 2nd Battery Pack can increase your battery operating
time. Note the caution on Standby mode in the previous section Battery
pack .
Real Time Clock (RTC) battery
The Real Time Clock (RTC) battery provides power for the internal real
time clock and calendar. It also maintains the system configuration.
If the RTC battery becomes completely discharged, the system loses this
data and the real time clock and calendar stop working. The following
message appears when you turn on the power:
S
**** RTC battery is low or CMOS checksum is inconsistent ****
Press [F1] key to set Date/Time.
You can change the setting of RTC by pressing F1 key. Refer to Chapter 9
Troubleshooting for details.
Always use the High Capacity 2nd Battery Pack supplied as an accessory
or an equivalent High Capacity 2nd Battery Pack specified in the User's
Manual. Other battery packs have different voltage and terminal polarities.
Use of non-conforming battery packs could generate smoke or cause fire
or rupture, possibly resulting in serious injury.
You can purchase optional High Capacity 2nd Battery Packs from your
dealer.
The computer’s RTC battery is a Ni-MH battery and should be replaced
only by your dealer or by a TOSHIBA service representative. The battery
can explode if not properly replaced, used, handled or disposed of.
Dispose of the battery as required by local ordinances or regulations.
