Power and Power-Up Modes

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.

2nd battery pack (option)

An optional 2nd battery pack can be installed in the Slim Select Bay to increase your battery operating time. Note the caution on Standby mode in the previous section Battery pack.

The 2nd 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.

Use 2nd battery with main battery. If you use computer with the 2nd battery only. Performance deterioration may occur.

Extended capacity battery pack (option)

An optional Extended capacity battery pack is installable instead of a main battery pack. The connection method of Extended 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 and optional 2nd 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 Extended capacity battery pack is connected to the computer, do not hold on only to the Extended capacity battery pack when lifting the computer up.

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