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 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 notebook and connect the power adapter.
MAKE SURE THAT THE BATTERY CHARGING INDICATOR AND THE PERCENTAGE CHARGE IS DISPLAYED BY THE BATTERY LEVEL INDICATOR ON THE STATUS INDICATOR PANEL.
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 58 for more information on sleep mode and shutdown procedure)
