54 - Lithium ion Battery
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.
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
49 for more information on Standby mode and shutdown procedure)
•DO NOT LEAVE A FAULTY BATTERY IN YOUR LIFEBOOK NOTEBOOK. IT MAY DAMAGE YOUR AC ADAPTER 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
(1-800-838-5487).
ACTUAL BATTERY LIFE WILL VARY BASED ON SCREEN BRIGHTNESS, APPLICATIONS, 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.
MAKE SURE THAT THE BATTERY CHARGING INDICATOR AND THE PERCENTAGE CHARGE IS DISPLAYED
BY THE BATTERY LEVEL INDICATOR ON THE STATUS INDICATOR PANEL.
