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 HDD/SSD, 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. You can change the Real Time Clock settings in the TOSHIBA Setup Utility. Please refer to Real Time Clock for further information. The computer's RTC battery is rechargeable 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. 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. Make sure the battery is securely installed in the computer before attempting to charge the battery pack. Improper installation could generate smoke or fire, or cause the battery pack to rupture. Keep the battery pack out of reach of infants and children. It can cause injury. The lithium ion battery pack can explode if not replaced, used, handled or disposed of properly. Dispose of the battery as required by local ordinances or regulations. Use only batteries recommended by TOSHIBA as replacements. User's Manual 4-24
