Lithium Ion Battery
Your Fujitsu LifeBook notebook has a Lithium Ion
battery that provides power for operating your notebook
when no external power source is available. The battery
is durable and long lasting, but should not be exposed
to extreme temperatures, high voltages, chemicals or
other hazards.
The Lithium Ion battery operating time may become
shorter if it is used under the following conditions:
■
When used at temperatures that exceeds a low of
5˚C or a high of 35˚C. Extreme temperatures not
only reduce charging efficiency, but can also cause
battery deterioration. The Charging icon on the
Status Indicator panel will flash when you try to
charge a battery that is outside its operating temp-
erature range. (See Battery Charging Indicators on
page 17 for more information)
■
When using a high current device such as a modem,
DVD drive, CD-ROM drive, or the hard drive, using
the AC adapter will conserve your battery life.
RECHARGING THE BATTERIES
If you want to know the condition of the primary
Lithium Ion battery, check the Battery Level indicator
located on the Status Indicator panel. The indicator
changes as the battery level changes.
The Lithium Ion battery is recharged internally using
the AC adapter or Auto/Airline adapter. To recharge the
battery make sure the battery that needs to be charged
is installed in your notebook and connect the AC or
Auto/Airline adapter.
There is no memory effect on the Lithium Ion battery
therefore you do not need to discharge the battery
completely before recharging. The charge times will be
significantly longer if your notebook is in use while the
battery is charging. If you want to charge the battery
more quickly, put your notebook into Suspend mode,
or turn it off while the adapter is charging the battery.
(See Power Management on page 36 for more information
on Suspend mode and shutdown procedure)
CAUTION
Actual battery life will vary based on screen brightness,
applications, features, power management settings,
battery condition and other customer preferences.
DVD drive, CD-RW Drive, CD-ROM drive or hard drive
usage may also have a significant impact on battery life.
The battery charging capacity is reduced as the battery
ages. If your battery is running low quickly, you should
replace it with a new one.
CAUTION
Do not leave a faulty battery in your notebook. It
may damage your AC adapter, optional Auto/Airline
adapter, another battery or your notebook itself. It may
also prevent operation of your notebook by draining all
available current into the bad battery.
CAUTION
Under federal, state, or local law it may be illegal to dis-
pose of batteries by putting them in the trash. Please
take care of our environment and dispose of batteries
properly. Check with your local government authority
for details regarding recycling or disposing of old bat-
teries. If you cannot find this information elsewhere,
contact your support representative at 1-800-8FUJITSU
(1-800-838-5487).
POINT
Make sure that the Battery Charging indicator and the
percentage charge is shown inside the Battery Level icon
on the Status Indicator Panel.
CAUTION
Using heavy current devices such as Modem or
frequent DVD/CD-RW/CD-ROM accesses may
prevent charging completely.
