Appendix A. Important safety information

Safety notices

This information can help you safely use your 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

Limited Warranty. For more information, see "Warranty Information" in the Safety and Warranty Guide that

comes with your computer.

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, 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 might merely mean that

an internal electronic component has failed in a safe and controlled manner. Or, they might indicate a

potential safety issue. 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

the following Web site:

https://pcsupport.lenovo.com/supportphonelist

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.

• Signs that liquid has been spilled or an object has fallen onto the computer product, the power cord, or

power adapter.

• The computer product, power cord, or power adapter has been exposed to water.

• The product has been dropped or damaged in any way.

• The product does not operate normally when you follow the operating instructions.

Note: If you notice these conditions with a product (such as an extension cord) that is not manufactured for

or by Lenovo, stop using that product until you can contact the product manufacturer for further instructions,

or until you get a suitable replacement.

Service and upgrades

Do not attempt to service a product yourself unless instructed to do so by the Customer Support Center or

your documentation. Only use a Service Provider who is approved to repair your particular product.

Note: Some computer parts can be upgraded or replaced by the customer. Upgrades typically are referred

to as options. Replacement parts approved for customer installation are referred to as Customer

Replaceable Units, or CRUs. Lenovo provides documentation with instructions when it is appropriate for

customers to install options or replace CRUs. You must closely follow all instructions when installing or

replacing parts. The Off state of a power indicator does not necessarily mean that voltage levels inside a

product are zero. Before you remove the covers from a product equipped with a power cord, always ensure

that the power is turned off and that the product is unplugged from any power source. If you have any

questions or concerns, contact the Customer Support Center.

The WEEE marking on Lenovo products applies to countries with WEEE and e-waste regulations (for

example, the European WEEE Directive, India E-Waste Management Rules). Appliances are labeled in

accordance with local regulations concerning waste electrical and electronic equipment (WEEE). These

regulations determine the framework for the return and recycling of used appliances as applicable within

each geography. This label is applied to various products to indicate that the product is not to be thrown

away, but rather put in the established collection systems for reclaiming these end of life products.

Users of electrical and electronic equipment (EEE) with the WEEE marking must not dispose of end of life

EEE as unsorted municipal waste, but use the collection framework available to them for the return, recycle,

and recovery of WEEE and to minimize any potential effects of EEE on the environment and human health

due to the presence of hazardous substances. Lenovo electrical and electronic equipment (EEE) may contain

parts and components, which at end-of-life might qualify as hazardous waste.

EEE and waste electrical and electronic equipment (WEEE) can be delivered free of charge to the place of

sale or any distributor that sells electrical and electronic equipment of the same nature and function as the

used EEE or WEEE.

Battery recycling information for the European Union

Notice: This mark applies only to countries within the European Union (EU).

Batteries or packaging for batteries are labeled in accordance with European Directive 2006/66/EC

concerning batteries and accumulators and waste batteries and accumulators. The Directive determines the

framework for the return and recycling of used batteries and accumulators as applicable throughout the

European Union. This label is applied to various batteries to indicate that the battery is not to be thrown

away, but rather reclaimed upon end of life per this Directive.

In accordance with the European Directive 2006/66/EC, batteries and accumulators are labeled to indicate

that they are to be collected separately and recycled at end of life. The label on the battery may also include

a chemical symbol for the metal concerned in the battery (Pb for lead, Hg for mercury, and Cd for cadmium).

Users of batteries and accumulators must not dispose of batteries and accumulators as unsorted municipal

waste, but use the collection framework available to customers for the return, recycling, and treatment of

batteries and accumulators. Customer participation is important to minimize any potential effects of batteries

and accumulators on the environment and human health due to the potential presence of hazardous

substances.

Before placing electrical and electronic equipment (EEE) in the waste collection stream or in waste collection

facilities, the end user of equipment containing batteries and/or accumulators must remove those batteries

and accumulators for separate collection.
