Chapter 2. Using your computer

When you charge the battery, make sure that its temperature is between 0° and 60°C (32° - 140°F).

„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 immediately when it drops from fully-charged.
