Learn How to Achieve All Day Computing

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 where ever 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:
1. Right -click the taskbar, and then click Properties.
2. Click the Notification Area tab.
3. Under 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. Because 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:
• How much energy is stored in the battery when you begin to work.
• The 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.
The AC adapter that comes with your computer has two basic components:
1. The transformer pack that converts AC power for use with the
computer.
2. The power cord that plugs into the AC outlet and into the transformer
pack.
Attention:
To use the AC adapter, do the following. Be sure to take these steps in the
order in which they are given here.
1. Connect the power cord to the transformer pack.
2. Plug the power cord into an electrical outlet.
