Chapter 2. Using Your Computer

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.

Note:

To increase the life of the battery, the computer does not start recharging

the battery if the remaining power is no less than 95 percent.
