Lithium Ion Battery; Recharging The Batteries - Fujitsu LifeBook S Series 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 exceed 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 Battery Charging icon on the Status
Indicator panel will flash when you try to
charge a battery that is outside its operating
temperature range.
• When using a high current device such as a
modem, optical drive, or the hard drive, using
the AC adapter will conserve your battery life.
Do not leave a faulty battery in your LifeBook
notebook. It may damage your AC adapter,
battery or your notebook itself. It may also
prevent operation of your notebook by
draining all available current into the bad
battery.
Actual battery life will vary based on
screen brightness,applications, features,
power management settings,battery
condition and other customerpreferences.
Optical drive or hard drive usage will also
have a significant impact on battery life.
The batterycharging 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.
The Lithium ion battery is recharged internally
using the AC adapter. To recharge the battery
make sure the battery that needs to be charged
is installed in your LifeBook notebook and
connect the AC adapter.
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.
Using heavy current devices such as a
modem or frequent media drive accesses
may prevent charging completely.
Low Battery State
When the battery is running low, a low battery
notification 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.
