Power and Power-Up Modes

■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 Standby Mode. Data is stored in RAM, so if the computer loses power it will be lost. When the computer is powered off in Standby 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, Standby 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. 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 battery pack (option)

An optional High capacity battery pack is installable instead of a main battery pack. The connection method of High capacity battery pack is the same as that of main battery pack.

■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.

■Do not remove the battery pack while the computer is in Standby Mode. Data is stored in RAM, so if the computer loses power it will be lost. When the computer is powered off in Standby Mode, and the AC adaptor is not connected, the main battery pack supply power to maintain data and program in memory. If the battery pack is completely discharged, Standby Mode does not function and the computer loses all data in memory.

■When the High capacity battery pack is connected to the computer, do not hold on only to the High capacity battery pack when lifting the computer up.

The High capacity battery pack may separate from the computer, causing it to fall and cause injuries.
