Tips for cleaning the multi-touch screen
• Turn off the computer before cleaning the multi-touch screen.
• Use a dry, soft, and lint-free cloth or a piece of absorbent cotton to remove fingerprints or dust from the
multi-touch screen. Do not apply solvents to the cloth.
• Gently wipe the screen using a top-down motion. Do not apply any pressure on the screen.
Power management
The power to run your computer comes either from the ac power provided by the ac power adapter of your
computer, or from the lithium-ion (Li-ion) battery provided with your computer. While you use ac power, the
battery charges automatically.
When you use your computer away from electrical outlets, 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.
Using the ac power adapter
The ac power adapter that comes with your computer has two basic components:
• The ac power adapter that converts ac power for use with the computer.
• The power cord that connects to the ac outlet and to the ac power adapter.
Attention: Using an improper power cord could severely damage your computer.
Connecting the ac power adapter
To connect the ac power adapter, do the following:
Note: Ensure that you perform the actions in the order in which they are listed.
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 when the power cord is connected to
the ac power adapter.
• Before you charge the battery, make sure that the battery temperature is at least 10°C (50°F).
Checking the battery status
The battery status icon in the lower-right corner of the screen displays the percentage of battery power
remaining. To check for detailed battery status information, click the battery status icon.
The rate at which you use battery power will determine how long you can use the battery of your computer
between charges. Because each computer user has different habits and needs, it is difficult to predict how
long a battery charge will last. There are two main factors:
• How much energy is stored in the battery when you begin to work.
• The way you use your computer. For example:
– How bright you make the computer display.
