Lithium Ion Battery; Recharging The Batteries - Fujitsu LifeBook N 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:
• 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 deterioration will
greatly increase. The Battery Charging
indicator on the Status Indicator Panel will flash
orange when you try to charge a battery that
is outside its operating temperature range.
• 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, features,
power management settings, battery
condition and
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
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, 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 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.

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. To recharge the battery,
make sure the battery is installed in your
notebook and connect the AC 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.
Using heavy current devices such as a
modem or frequent media player accesses
may prevent charging completely.
