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
