Lithium Ion Battery; Recharging The Batteries - Fujitsu DVD Player User Manual

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 14 for more information)
When using a high current device such as a modem,
DVD, CD-ROM, CD-RW drive, or the hard drive,
using the AC adapter will conserve your battery life.
C A U T I O N S
Actual battery life will vary based on screen bright-
ness, applications, features, power management set-
tings, battery condition and other customer
preferences.DVD, CD-RW, CD-ROM, 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.
Under federal, state, or local law it may be illegal to
dispose 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 batteries. If you cannot find this information
elsewhere, contact your support representative at 1-
800-8FUJITSU (1-800-838-5487)
Do not leave a faulty battery in your LifeBook note-
book. It may damage your AC adapter, optional
Auto/Airline adapter, another battery or your note-
book itself. It may also prevent operation of your
notebook by draining all available current into the
bad battery.

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
U s e r I n s t a l l a b l e F e a t u r e s
battery make sure the battery that needs to be charged
is installed in your LifeBook notebook and connect the
AC or Auto/Airline adapter.
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.
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)
C A U T I O N
Using heavy current devices such as Modem or
frequent DVD/CD-RW/CD-ROM accesses may
prevent charging completely.
Low Battery State
When the battery is running low, a low battery notifica-
tion message will appear. If you do not respond to the
low battery message, the batteries will continue to
discharge until they are too low to operate. When this
happens, your notebook will go into Suspend mode.
There is no guarantee that your data will be saved once
the notebook reaches this point.
C A U T I O N S
Once the low battery notification message appears,
you need to save all your active data and put your
LifeBook notebook into Suspend mode until you can
provide a new power source. You should provide a
charged battery, an AC power adapter, or Auto/Air-
line adapter as soon as possible.
When you are in Suspend mode there must always
be at least one power source active. If you turn off
the power with the power switch, or remove all
power sources while your LifeBook notebook is in
Suspend mode, any data that has not been saved to
the hard drive will be lost.
Dead Battery Suspend mode shows on the Status indi-
cator just like the normal Suspend mode. Once your
notebook goes into Dead Battery Suspend mode you
will be unable to resume operation until you provide
