Note: 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 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.
Note: Make sure that the battery charging indicator
and the Battery Level indicator icon on the Status
Indicator panel light.
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 for more information on Standby mode
and Shutdown Procedure).
Note: Using heavy-current devices or frequent
external optical drive accessories may prevent
complete charging.
