Chapter 2. Using Your Computer

The AC adapter that comes with your computer has two basic components:

1The transformer pack that converts AC power for use with the computer.

2The power cord that plugs into the AC outlet and into the transformer pack.

Attention:

Using an improper power cord could cause severe damage to your computer.

To use the AC adapter, do the following. Be sure to take these steps in the order in which they are given here.

1Connect the power cord to the transformer pack.

2Plug the power cord into an electrical outlet.

3Connect the AC adapter to the AC power adapter jack of the computer.

You can check the status of your battery at any time by looking at the battery meter at the bottom of your display.

Notes:

When you do not use the AC adapter, disconnect it from the electrical outlet.

Do not wrap the power cord tightly around the AC power transformer pack when it is connected to the transformer.

You can charge the battery when the AC adapter is connected to the computer and the battery is installed. You need to charge it in any of the following conditions:

When you purchase a new battery

If the battery status indicator (amber) starts blinking

If the battery has not been used for a long time

Before you charge the battery, make sure that its temperature is at least 10 degrees Celsius (50 degrees Fahrenheit).

Charging the Battery

When you check the battery status and find that the battery is low, you need to charge the battery or replace it with a charged battery.

If an AC outlet is convenient, first, connect the power cord to the transformer pack; second, plug the power cord into an electrical outlet; and then connect the AC adapter to the power jack of the computer.

The charging time is affected by the physical environment.
