Important safety information

Note:
Read important safety information first.
This information can help you safely use your notebook personal 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 Lenovo
Limited Warranty. For more information, see Chapter 3, Warranty Information in
the Safety and Warranty Guide. The latest Safety and Warranty Guide has been
uploaded on the Web site. See "Notice for Safety and Warranty information"
on page 25.
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.

Conditions that require immediate action

Products can become damaged due to misuse or neglect. Some product
damage is serious enough that the product should not be used again until it
has been inspected and, if necessary, repaired by an authorized servicer.
As with any electronic device, pay close attention to the product when it is
turned on. On very rare occasions, you might notice an odor or see a puff
of smoke or sparks vent from your product. Or you might hear sounds like
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,
