Chapter 1. Important safety information

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

This information can help you safely use your desktop or 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, refer to

Chapter 5, “Lenovo Limited Warranty,” on page 39.

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.

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 Service

Provider.

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, see Chapter 6, “Worldwide telephone list,” on page 59.
