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.

Although there are no moving parts in your computer after the power cord has been disconnected, the

following warnings are required for your safety.

Keep fingers and other parts of your body away from hazardous, moving parts. If you suffer an injury, seek

medical care immediately.

Avoid contact with hot components inside the computer. During operation, some components become hot

enough to burn the skin. Before you open the computer cover, turn off the computer, disconnect power, and

wait approximately 10 minutes for the components to cool.

After replacing a CRU, reinstall all protective covers, including the computer cover, before connecting power

and operating the computer. This action is important to help prevent unexpected electrical shock and help

ensure the containment of an unexpected fire that could happen under extremely rare conditions.

Important battery recycling and WEEE information

Take back and recycling information for WEEE and batteries/accumulators in the European Union and the

United Kingdom

The crossed-out wheeled bin marking applies only to countries with WEEE and batteries waste regulations

including the European Union (EU), and United Kingdom (UK).

Appliances and batteries/accumulators are labeled in accordance with local regulations concerning waste

electrical and electronic equipment (WEEE) and waste batteries and waste accumulators. These regulations

determine the framework for the return and recycling of used appliances and used batteries/accumulators 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.

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 electrical and electronic equipment (EEE) and users of batteries/accumulators with the crossed-out

wheeled bin marking must not dispose of end of life products as unsorted municipal waste, but use the

collection framework available to them for the return, recycle, and recovery of WEEE and waste batteries/

accumulators and to minimize any potential effects of EEE and batteries 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.

Appendix C. Compliance information 41

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.
