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. For more information

on CRUs, refer to Chapter 9 "Installing or replacing hardware" on page 73. 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.

CAUTION:

Hazardous moving parts. Keep fingers and other body parts away.

CAUTION:

Before replacing any CRUs, turn off the computer and wait three to five minutes to let the computer

cool before opening the cover.
