Battery Pack; Running The Notebook On Battery Power - HP Compaq NC6140 Hardware Manual

Running the Notebook on Battery Power

When the notebook is connected to external AC power, the
notebook runs on AC power.
When a charged battery pack is in the notebook and the notebook
is not connected to external AC power, the notebook runs on
battery power.
The notebook switches between AC power and battery power
according to the availability of an external AC power source. For
example, if the notebook contains a charged battery pack and is
running on external AC power supplied through the AC Adapter,
the notebook will switch to battery power if the AC Adapter is
disconnected from the notebook.
Whether to leave a battery pack in the notebook or in storage
depends on how you work. Keeping a battery pack in the
notebook enables the battery pack to charge whenever the
notebook is connected to external AC power and also protects
your work in case of a power outage.
On the other hand, a battery pack in the notebook slowly
discharges when the notebook is turned off.
If you will not be using the notebook for 2 weeks or more,
removing the battery pack and storing it as described in "Storing
a Battery Pack," later in this chapter, will prolong its life. For
more information about leaving your work, see the Software
Guide, Chapter 1, "Power Management," on this CD.
One lithium ion battery pack is included with the notebook.
