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 this lithium ion battery pack, also referred to in this manual as the main battery.
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.
You can change the Real Time Clock settings in the BIOS setup utility. Please refer to 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.
Refer to the enclosed Instruction Manual for Safety and Comfort for detailed precautions and handling instructions.
The computer's RTC battery is a lithium ion battery and should be replaced only by your dealer or by a TOSHIBA service representative. The battery can explode if not properly replaced, used, handled or disposed. Dispose of the battery as required by local ordinances or regulations.
Charge the battery pack only in an ambient temperature between 5 and 35 degrees Celsius. Otherwise, the electrolyte solution might leak, battery pack performance might deteriorate and the battery life might be shortened.
Charging the batteries
When the power in the battery pack becomes low, the DC IN/Battery indicator will flash amber to indicate that only a few minutes of battery power remain. If you continue to use the computer while the DC IN/Battery indicator flashes, the computer will enable Hibernation Mode so that you do not lose any data, and automatically turn itself off.
You must recharge a battery pack when it becomes discharged.
