Battery

When the AC power cord is not connected, the computer’s main power source is a removable lithium ion battery pack, also referred to in this manual as the battery. You can purchase additional 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.

The battery recharges the RTC battery. The battery maintains the state of the computer when you enable Resume.

When the computer is powered off in hibernation and standby mode, and the AC adaptor is not connected, the battery pack supply power to maintain data and programs in memory. If the battery pack is completely discharged, hibernation and standby mode do not function and the computer loses all data in memory.

One of the following messages appears when you turn on the power:

■The firmware has detected that a CMOS battery fail occurred.<F1> delete

■The firmware has detected that a CMOS battery fail occurred.<F1> delete, <F2> to setup
