Battery Pack
Charging 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.
❏ When you charge the battery pack, charge it fully.
A battery pack inserted in the notebook charges whenever the
notebook is connected to external power through an AC adapter,
an
optional docking device, or an optional combination power
adapter.
