This section provides information about how to use ac power and battery power to achieve the best balance
between performance and power management.
Using the ac power adapter
The power to run your computer can come either from the battery or from ac power. While you use ac power,
the battery charges automatically.
Your computer comes with an ac power adapter and a power cord.
• ac power adapter: Converts ac power for notebook computer use.
• Power cord: Connects the ac outlet and the ac power adapter.
Connecting the ac power adapter
To connect the computer to ac power, ensure that you follow the steps in order:
Attention: Using an improper power cord might severely damage your computer.
1. Connect the power cord to the ac power adapter.
2. Connect the ac power adapter to the power connector of the computer.
3. Connect the power cord to an electrical outlet.
Tips on using the ac power adapter
• 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 adapter transformer pack when it is connected to
the transformer.
Battery
When your computer is not connected to ac power, you depend on battery power to keep your computer
running. Different computer components consume power at different rates. The more you use the power-
intensive components, the faster you consume battery power.
