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
52
for more information on Sleep mode and
shutdown procedure)
Low Battery State
When the battery is running low, a low battery notification message will appear. If you do not respond to the
message, the battery will continue to discharge until it is too low to operate. When this happens, your notebook will
go into Sleep mode. There is no guarantee that your data will be saved once the notebook reaches this point.
