Chapter 2. Using Your Computer

Using battery and AC adapter -----------------------------------------------

When you need to use your computer away from electrical outlets, you depend on battery power to keep your computer running. Different computer components consume power at different rates. The more you use the power-intensive components, the faster you consume battery power.

Your Computer Batteries

Your computer batteries enable you to do more, save more, and spend more time unplugged. Mobility has revolutionized business by enabling you to take your work wherever you go. With your computer batteries, you will be able to work longer without being tied to an electrical outlet.

Note:

The operating system may run slower when using the battery mode.
