Appendix A. Important safety information
Safety notices
This information can help you safely use your computer. Follow and retain all information included with your
computer. The information in this document does not alter the terms of your purchase agreement or the
Limited Warranty. For more information, see "Warranty Information" in the Safety and Warranty Guide that
comes with your computer.
Customer safety is important. Our products are developed to be safe and effective. However, personal
computers are electronic devices. Power cords, power adapters, and other features can create potential
safety risks that can result in physical injury or property damage, especially if misused. To reduce these risks,
follow the instructions included with your product, observe all warnings on the product and in the operating
instructions, and review the information included in this document carefully. By carefully following the
information contained in this document and provided with your product, you can help protect yourself from
hazards and create a safer computer work environment.
Note: This information includes references to power adapters and batteries. In addition, some products
(such as speakers and monitors) ship with external power adapters. If you have such a product, this
information applies to your product. In addition, computer products contain a coin-sized internal battery that
provides power to the system clock even when the computer is unplugged, so the battery safety information
applies to all computer products.
Important information about using your computer
Ensure that you follow the important tips given here to get the most use and enjoyment out of your computer.
Failure to do so might lead to discomfort or injury, or cause the computer to fail.
Protect yourself from the heat that your computer generates.
When your computer is turned on or the battery is charging, the base,
the palm rest, and some other parts may become hot. The
temperature they reach depends on the amount of system activity and
the level of charge in the battery.
Extended contact with your body, even through clothing, could cause
discomfort or even a skin burn.
Avoid keeping your hands, your lap, or any other part of your body
in contact with a hot section of the computer for any extended
time.
Periodically take hands from using the keyboard by lifting your
hands from the palm rest.
