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.

„Checking Battery Status

You can determine the percentage of battery power remaining by using Windows Power options.

To display the Battery icon in the taskbar, do as follows:

1Right-click the taskbar, and then select Properties from the pull down menu.

2Click the Notification Area tab.

3Under System icons, select the Power check box.

The rate at which you use battery power determines how long you can use the battery of your computer between charges. As each computer user has different habits and needs, it is difficult to predict how long a battery charge will last. There are two main factors:

ƒThe amount of energy stored in the battery when you begin to work.

ƒThe way you use your computer: for example, how often you access the hard disk drive and how bright you make the computer display.

„Using the AC Adapter

The power to run your computer can come either from the lithium-ion (Li-ion) battery pack provided with it, or from AC power through the AC adapter. While you use AC power, the battery charges automatically.
