- 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 Tablet PC 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 Tablet PC is in use

while the battery is charging. If you want to charge the battery more quickly, put your Tablet PC into Sleep

mode, or turn it off while the adapter is charging the battery. (See Power Management on page 77 for more

information on Sleep mode and shutdown procedure)

• ACTUAL BATTERY LIFE WILL VARY BASED ON SCREEN BRIGHTNESS, APPLICATIONS, 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. 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)

AKE SURE THAT THE PERCENTAGE CHARGE IS INDICATED BY THE BATTERY CHARGING INDICATOR ON

THE STATUS INDICATOR PANEL.
