Battery
This section explains battery types, use, recharging methods and handling.
Battery types
The computer has different types of batteries.
Battery pack
When the AC adaptor is not connected, the computer's main power source 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. Please be aware that, when placing the computer into Hibernation Mode, the contents of memory will be saved to the hard disk drive, although for safety sake, it is best to also save your data manually.
Real Time Clock (RTC) battery
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 - in this instance the following message will be displayed when you turn on the power:
****RTC Power Failure **** Check system. Then press [F2] key.
You can change the Real Time Clock settings by turning on the computer while pressing the F2 key and then release F2 key when the TOSHIBA Leading Innovation >>> screen appears. Please refer to Chapter 6 Troubleshooting for further information.
Care and use of the battery pack
This section provides the important safety precautions in order to handle your battery pack properly.
