Recharging the Battery Pack
1. Connect the notebook to external power and maintain the
connection until the battery pack is fully recharged. The
battery light on the notebook turns off.
You can use the notebook while the battery pack is recharging
but the battery pack will charge faster if the notebook is off.
2. If the notebook is off, turn it on when the battery pack is fully
charged and the battery light turns off.
