Chapter 1. Important safety information

Read this first

This information can help you safely use your 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

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, go to

Frequently inspect your computer and its components for damage or wear or signs of danger. If you have
any question about the condition of a component, do not use the product. Contact the Customer Support
Center or the product manufacturer for instructions on how to inspect the product and have it repaired, if
necessary.

In the unlikely event that you notice any of the following conditions, or if you have any safety concerns with
your product, stop using the product and unplug it from the power source and telecommunication lines until
you can speak to the Customer Support Center for further guidance.

• Power cords, plugs, power adapters, extension cords, surge protectors, or power supplies that are

cracked, broken, or damaged.

• Signs of overheating, smoke, sparks, or fire.

• Damage to a battery (such as cracks, dents, or creases), discharge from a battery, or a buildup of foreign

substances on the battery.

• A cracking, hissing, or popping sound, or strong odor that comes from the product.
