Lithium Ion Battery; Recharging The Batteries - Fujitsu Lifebook B2630 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:
When used at temperatures that exceeds a low of
40°F (5°C) or a high of 95°F (35°C). Extreme tempera-
tures 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 13.
When using a high current device such as a modem,
CD-ROM drive, or the hard drive, using the AC
adapter will conserve your battery life.
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.
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.
P O I N T
Actual battery life will vary based on screen brightness,
applications, features, power management settings,
battery condition and other customer preferences.
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.

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.
U s e r I n s t a l l a b l e F e a t u r e s
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.
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 Standby mode,
or turn it off while the adapter is charging the battery.
See "Power Management" on page 32.
P O I N T
Using heavy current devices such as Modem or
frequent CD-ROM and PCMCIA powered external
devices accesses may prevent charging completely.
Low Battery State
When the battery is running low, your LifeBook note-
book will beep every 15 seconds and the Battery Level
indicator will flash. If you do not respond to the low
battery alarm, the batteries will continue to discharge
until they are too low to operate. When this happens
there will be a multiple beep alarm and the Battery Level
indicator will show a dead battery. Your LifeBook will
then go into Standby mode to try and protect your data
for as long as possible. There is no guarantee that your
data will not be lost once the notebook reaches this
point.
C A U T I O N
You may not be able to hear the audio alarm if the
volume control is set too low or is turned off by either
the hardware or software. However, you will still be
able to see the Battery Level indicator flash. Once the
low battery alarm occurs you must save all your active
data and put your notebook into Standby mode until
you can provide a new power source. You should
provide a charged battery, an AC power adapter, or
Auto/Airline as soon as possible.
When you are in Standby mode there must always be
at least one power source active. If you remove all
power sources while your notebook is in Standby
mode, any data that has not been saved to the hard
drive will be lost.
