Mobile Computing
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. 

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.

❖

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
