Battery PackCharging a Battery Pack
To prolong battery life and optimize the accuracy of battery
charge displays:
■If you are charging a new battery pack:
❏Charge the battery pack while the notebook is connected
to external power through the AC adapter.
❏When you charge the battery pack, charge it fully.
■If you are charging an in-use battery pack:
❏Allow the battery pack to discharge to about 10 percent
of a full charge through normal use before charging it.

notebook is connected to external power through an AC adapter,
an optional docking device, or an optional combination power
adapter.
