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 ***
Check system. Then press [F1] key . . . . .
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.
Care and use of the battery pack
The battery pack is a vital component of portable computing. Taking
proper care of it will help ensure longer operating time on battery power
as well as a longer life for your battery pack. Follow the instructions in this
section carefully to ensure safe operation and maximum performance.
Safety precautions
1.
Be very careful not to short-circuit the battery pack. Contacting both
terminals with a metal object can cause injury, fire or damage to the
battery pack.
2.
Do not overcharge, reverse charge, mutilate or disassemble the
battery. Any one of those actions could release toxic materials,
hydrogen and/or oxygen or other electrolytic substances or cause an
increase in the battery’s surface temperature.
3.
Do not expose the battery pack to fire; the battery pack could explode.
4.
Battery packs contain toxic substances. Do not dispose of them with
ordinary trash. Dispose of battery packs only in accordance with local
ordinances. Always cover the metal terminals with insulating tape to
avoid short circuits.
5.
If the battery has leaked or been vented, it should be replaced
immediately. Use protective gloves when handling a damaged battery.
6.
When it becomes necessary to replace the battery, it must be replaced
only by an identical battery from the same manufacturer.
