Important safety information

Ensure your computer and other components maintain good ventilation.

￿Danger:

•Placing the working computer or other parts on a bed, sofa or other flexible surface may block the ventilation slots causing overheating of your computer or other parts and increases the risk of fire.

Turn off wireless devices where they may cause interference, such as in a hospital or at an airport.

Correct usage procedures

Use ONLY the power cord, power adapter and battery pack shipped with the computer. Never use these devices with another product.

Be sure the power outlet is suitable for the plug and provides the correct voltage and current for the product you are using.

￿Danger:

•An unsuitable power supply may damage your computer and can cause an electric shock or fire.

Do NOT use a power outlet, power cord, power adapter or battery pack that appears to be damaged or corroded.

Do NOT share an electrical outlet with other home or commercial appliances that draw large amounts of electricity.

If power strips are used, the load should NOT exceed the power strip’s input rating. Unplug the power cord if there are any cracking, hissing, or popping sounds, or if a strong odor comes from the computer.

￿Danger:

•Overloading the power supply may cause unstable voltages which might damage the computer, data, attached devices, or even cause a fire.

Do NOT wrap the power cord around the power adapter or other object.

Do NOT squeeze or pinch the cord, or place heavy objects on it.

￿Attention:

•Stressing the cord may cause the cord to fray, crack or crimp which may present a safety hazard.

Avoid keeping your hands, your lap, or any other part of your body in contact with a hot section of the working computer for any extended length of time.

￿Attention:

•Extended contact with your body, even through clothing, could cause discomfort or even a skin burn.
