Power ■ The 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. ■ Always use the battery pack supplied as an accessory or an equivalent 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. ■ Always dispose of used battery packs in compliance with all applicable laws and regulations. Put insulating tape, such as cellophane tape, on the electrode during transportation to avoid a possible short circuit, fire or electric shock. Failure to do so could possibly result in serious injury. ■ Do not remove the battery pack while the computer is in Sleep Mode. Data is stored in RAM, so if the computer loses power it will be lost. When the computer is powered off in Sleep Mode, and the AC adaptor is not connected, the battery pack supplies power to maintain data and programs in memory. If the battery pack is completely discharged, Sleep Mode will not function and the computer loses all data in memory. 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 - please refer to Extending battery life in this chapter for details of the procedure. If the computer is continuously operated on AC power through connection to an AC adaptor for an extended period, for example more than a month, the battery may fail to retain a charge, it may not function efficiently over its expected life and the Battery indicator may not properly indicate a lowbattery condition. Real Time Clock battery The Real Time Clock (RTC) battery provides power for the internal real time clock and calendar function and also maintains the system configuration while the computer is turned off. If the RTC battery becomes completely discharged, the system will lose this information and the real time clock and calendar will stop working - in this instance the following message will be displayed when you turn on the power: S ERROR 0271: Check date and time settings. WARNING 0251: System CMOS checksum bad Default configuration used. Press to resume, to Setup. User's Manual 6-4
