Secondary Battery (Option); Real Time Clock Battery; Care And Use Of The Battery Pack - Toshiba Satellite 5200 Series User Manual

User's Manual
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.

Secondary battery (option)

An optional secondary battery can be installed in the TOSHIBA Style Bay to
increase your battery operating time. Note the caution on Standby mode in the
previous section Main battery.
CAUTION: The secondary battery pack is a lithium ion battery, which
can explode if not properly replaced, used, handled or disposed of.
Dispose of the battery as required by local ordinances or regulations.
Use only batteries recommended by TOSHIBA as replacements.

Real Time Clock 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:
**** Bad RTC battery ****
Press [F1] key for default setting.
CAUTION: The computer's RTC battery is a nickel metal hydride
(NiMH) 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.
