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. See “Battery
Level Indicators” on page 24.
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.
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 Sleep
mode, or turn it off while the adapter is charging the battery. (See Power Management on page 58 for more
information on Sleep mode and shutdown procedure)
• ACTUAL BATTERY LIFE WILL VARY BASED ON SCREEN BRIGHTNESS, APPLICATIONS USED, FEATURES,
POWER MANAGEMENT SETTINGS, BATTERY CONDITION AND OTHER CUSTOMER PREFERENCES.
OPTICAL 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.
• 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. REFER TO “RECYCLING YOUR BATTERY” ON PAGE 5 FOR INFORMATION ON PROPER
DISPOSAL OF YOUR BATTERY.
