100 Mobile Computing Running the computer on battery power Running the computer on battery power The computer contains a removable lithium ion (Li-ion) high-capacity battery that provides power when you are away from an AC outlet. You can recharge it many times. In addition, the computer has an internal real-time clock (RTC) battery. This is a nickel metal hydride (NiMH) battery. The RTC battery powers the RTC memory, which stores your system configuration settings and the current time and date for up to a month while the computer is turned off. Using additional battery packs If you spend a lot of time traveling and need to work for many hours without an AC power source, you may want to carry additional charged batteries with you. You can then replace a discharged battery and continue working. Battery safety precautions ❖ Never try to disassemble a battery. ❖ Never overcharge or reverse charge a battery. Overcharging will shorten its life and reverse charging could destroy it, causing the release of toxic fumes. ❖ Avoid touching the metal terminals of the battery with another metal object. Short-circuiting the battery will cause it to overheat and may cause permanent damage to the battery or the computer. ❖ Never incinerate a spent battery as this will cause it to explode, releasing toxic materials. ❖ If a battery is leaking or damaged, replace it immediately. Use protective gloves when handling a damaged battery. To replace the main battery, use an identical battery which you can purchase from Toshiba's Web site at toshibaaccessories.com.
