Note:
Be sure to read and understand the important safety information first.

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)
are shipped 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.

popping, cracking, or hissing. These conditions might merely mean that an
internal electronic component has failed in a safe and controlled manner. Or,
they might indicate a potential safety issue. However, do not take risks or
attempt to diagnose the situation yourself. Contact the Customer Support
Center for further guidance. For a list of Service and Support phone numbers,
