Battery pack
When the AC adaptor is not connected, the main power source of the
computer is a removable lithium ion battery pack, also referred to in this
manual as the main battery. You can purchase additional battery packs for
extended use of the computer away from an AC power source although
you should not change the battery pack while the AC adaptor is connected.
Before you remove the battery pack, save your data and shut down the
computer, or place the computer into Hibernation Mode. Be aware that,
when placing the computer into Hibernation Mode, the contents of memory
are saved to the internal storage drive, although for safety sake, it is best to
also save your data manually.

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.
You can change the Real-Time Clock settings in the TOSHIBA Setup
Utility. Refer to
