General safety guidelines

Always observe the following precautions to reduce the risk of injury and property damage.

Service

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

service provider who is approved to repair your particular product.

Note: Some parts can be upgraded or replaced by the customer. These parts are referred to as Customer Replaceable

Units, or CRUs. Lenovo expressly identifies CRUs as such, and provides documentation with instructions when it is

appropriate for customers to replace those parts. You must closely follow all instructions when performing such

replacements. Always make sure that the power is turned off and that the product is unplugged from any power source

before you attempt the replacement. If you have any questions or concerns, contact the Customer Support Center.

Power cords and power adapters

Use only the power cords and power adapters supplied by the product manufacturer.

Never wrap a power cord around the power adapter or other object. Doing so can stress the cord in ways that can cause

the cord to fray, crack or crimp. This can present a safety hazard.

Always route power cords so that they will not be walked on, tripped over, or pinched by objects.

Protect the cord and power adapters from liquids. For instance, do not leave your cord or power adapter near sinks, tubs,

toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a short circuit, particularly if the cord or

power adapter has been stressed by misuse. Liquids can also cause gradual corrosion of the power cord terminals and/or

the connector terminals on the adapter which can eventually result in overheating.

Always connect power cords and signal cables in the correct order and ensure that all power cord connectors are securely

and completely plugged into receptacles.
