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 power cord to the transformer pack.
2. Plug the power cord into an electrical outlet.
3. Connect 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 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).
