Using the Battery
A battery is an auxiliary power source you can use when your computer is not plugged into an AC outlet. Your computer
may come equipped with one or two battery bays, depending on the model you purchased. If your computer comes with
two battery bays, you can purchase a second rechargeable battery to extend your computing time. Regardless how many
batteries you use, you can always extend the life of the battery by conserving power. See
Conserving Battery Power for
more information.
