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 65 for more information on Sleep mode and shutdown procedure)
