You can purchase Battery Packs for extended use of the computer away from an AC power source. 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 battery recommended by TOSHIBA as replacements. Do not remove the battery pack while the computer is in Standby mode. Data is stored in RAMs, 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 program in memory. If the battery pack is completely discharged, Standby mode does 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 LED may not indicate a low battery condition.
