Chapter 2. Using Your Computer
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 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.
