Lithium Ion Battery; Recharging The Batteries - Fujitsu Lifebook A3040 User Manual

Lithium ion Battery

Your 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:
The operating temperature range of the Lithium ion
■
battery is 5°C to 30°C. If the battery is used outside
these temperature ranges, charging efficiency will be
greatly reduced and the likelihood of battery deterio-
ration will greatly increase. The Battery Charging indi-
cator on the Status Indicator Panel will flash orange
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.
■ Actual battery life will vary based on
screen brightness, applications, power
management settings, features, battery
condition and other user preferences.
Media player drive or hard drive usage
may also have a significant impact on
battery life. The battery charging capac-
ity is reduced as the battery 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, or your LifeBook notebook
itself. It may also prevent operation of
your notebook by draining all available
current 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. Take care of our
environment and dispose of batteries
properly. Check with your local govern-
ment authority for details regarding
recycling or disposing of batteries. If you
cannot find this information elsewhere,
contact your support representative at
1-800-8Fujitsu (1-800-838-5487).

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 (See Battery Level
Indicator on page 14 for more information). The indicator
changes as the battery level changes.
L i t h i u m i o n B a t t e r y
The Lithium ion battery is recharged internally using the
AC adapter or Auto/Airline adapter. To recharge the
battery, make sure the battery is installed in your note-
book and connect the AC or Auto/Airline adapter.
Make sure that the Battery Charging
indicator and the percentage charge is
indicated by the Battery Level icon on the
Status Indicator Panel.
It is not necessary to discharge the battery completely
before recharging. Charge times will be much 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 31 for more information on Suspend mode and
shutdown procedure
)
Using heavy current devices such as a modem
or frequent media player 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 LifeBook notebook will go into Suspend
mode. There is no guarantee that your data will be saved
once the notebook reaches this point
Once the low battery notification
■
message appears, you must 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.
Once your LifeBook notebook battery goes dead, you
will be unable to resume operation until you provide a
source of power either from an adapter or a charged
battery. Once you have provided power, you will need to
press the Power/Suspend/Resume button to resume
operation. If your battery dies, your data will be lost if a
power source is not provided promptly. Once you
provide power, you can continue to use your LifeBook
notebook while an adapter is charging the battery.
