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: 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.

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

2.Connect the power cord to the transformer pack.

3.Plug the power cord into an electrical outlet.

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 the AC adapter is not in use, 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 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).
