Lithium Ion Battery
Your Fujitsu Series 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 44 for more information 
on Suspend mode and shutdown procedure)

Actual battery life will vary based on screen brightness, 
applications, features, power management settings, 
battery condition and other customer preferences.
DVD 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.
C A U T I O N
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.
C A U T I O N
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).
P O I N T
Make sure that the Battery Charging indicator and the 
percentage charge is shown inside the Battery Level icon 
on the Status Indicator Panel.

Using heavy current devices such as Modem or
frequent DVD/CD-RW/CD-ROM accesses may
prevent charging completely.
