Lithium ion Battery
Your LifeBook notebook has a Lithium ion battery that
provides power for operating your LifeBook 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 exceed a low of 5°C or
a high of 35°C. Extreme temperatures not only reduce
charging efficiency, but can also cause battery deterio-
ration. The Battery Charging icon on the Status
Indicator Panel will flash when you try to charge a
battery that is outside its operating temperature range.
(See Battery Charging Indicator on page 14 for more
information)
■
When using a high current device such as a modem,
DVD, or hard drive, using the AC adapter will
conserve your battery life.
RECHARGING THE BATTERIES
If you want to know the charge 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 LifeBook notebook and connect the
AC or Auto/Airline adapter. The Lithium ion battery can
also be charged using an external battery charger, avail-
able from Fujitsu.
There is no memory effect on the Lithium ion battery,
therefore you do not need to discharge the battery
completely before recharging. Charge times will be
much longer if your LifeBook notebook is in use while
the battery is charging. If you want to charge the battery
more quickly, put your LifeBook notebook into Suspend
mode, or turn it off while the adapter is charging the
battery.
(See Power Management on page 30 for more
information on Suspend mode and shutdown procedure
)
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 LifeBook notebook will go into Suspend
mode. There is no guarantee that your data will be saved
once the notebook reaches this point.
■ Actual battery life will vary based on
screen brightness, applications, fea-
tures, power management settings, bat-
tery condition and other customer
preferences. Media player drive or hard
drive usage may also have a significant
impact on battery life. The battery
charging capacity is reduced as the bat-
tery ages. If your battery is running low
quickly, you should replace it with a new
one.
■ Do not leave a faulty battery in your
LifeBook notebook. It may damage your
AC adapter, optional Auto/Airline
adapter, a second battery or your Life-
Book notebook itself. It may also pre-
vent operation of your LifeBook
notebook by draining all available cur-
rent into the bad battery.
■ Under federal, state, or local law it may
be illegal to dispose of batteries by put-
ting them in the trash. Please take care
of our environment and dispose of bat-
teries properly. Check with your local
government authority for details regard-
ing recycling or disposing of old batter-
ies. If you cannot find this information
elsewhere, contact your support repre-
sentative at
1-800-8Fujitsu (1-800-838-5487).
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 a
modem or frequent media player accesses
may prevent charging completely.
■
Once the low battery notification
message appears, you need to either
plug in an AC power adapter or Auto/
Airline adapter, or save all your active
data, power down your system, and
install a charged battery as soon as
possible.
■ When you are in Suspend mode there
must always be at least one power
source active. If you 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.
