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)
