Charging a Battery Pack
The battery pack charges when it is inserted into the computer
and the computer is connected to external power. External power
can be supplied through the following:
■ AC adapter
■ Optional expansion product (select models only)
■ Optional power adapter
Å
WARNING: To reduce potential safety issues, only the AC adapter
provided with the computer, a replacement AC adapter provided by HP,
or a compatible battery pack purchased as an accessory from HP
should be used with this computer.
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 computer 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 computer charges whenever the
computer is plugged into external power through an AC adapter, an
optional power adapter, or docked in an optional expansion
product.
