Using the ac power adapter

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

The ac power adapter 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 the computer.

Connecting the ac power adapter

To connect the ac power adapter, do the following:

1.Plug the power cord into an electrical outlet.

2.Connect the power cord to the transformer pack.

3.Insert the power jack into the computer.

Tips on using the ac power adapter

When using the ac power adapter, observe the following guidelines:

•When the ac power adapter is not in use, disconnect it from the electrical outlet.

•Do not bind the power cord tightly around the ac power transformer pack when it is connected to the transformer.

•Before you charge the battery, make sure that its temperature is at least 10°C (50°F).

•You can charge the battery when the ac power adapter is connected to the computer and the battery is installed.

Charging the battery

When you find that the battery power is low, you need to charge the battery or replace it with a fully charged one.

You are recommended to charge the battery in any of the following situations:

•When you purchase a new battery

•If the battery status indicator starts blinking

•If the battery has not been used for a long time

Notes:

•You are advised to install the battery pack when using your computer to prevent small particles from entering the inside of your computer.

•To maximize the battery life, do not start recharging the battery immediately after it drops from full charge.

•Charge the battery at a temperature between 50 °F and 86 °F (10 °C-30 °C).
