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
to notebook computers, 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.
