Battery Packs
Running the Notebook on Battery 
Power
The notebook switches between AC power and battery power 
according to the availability of an external AC power source, 
always preferring AC power. If the notebook contains a charged 
battery pack and is running on external AC power, the notebook 
will switch to battery power only if the AC adapter is 
disconnected from the notebook.
Keeping a battery pack in the notebook enables the battery pack 
to charge whenever the notebook is connected to external power 
and also protects your work in case of a power outage.
On the other hand, a battery pack in the notebook slowly 
discharges even when the notebook is powered off. Whether to 
leave a battery pack in the notebook or in storage depends on how 
you work.
