Chapter 5. Customer Replaceable Units (CRUs)

Customer Replaceable Units (CRUs) are parts that can be upgraded or replaced

by the customer. There are two types of CRUs: self-service and optional-assist.

Self-service CRUs are easy to install, whereas optional-assist CRUs require

some technical skills and in some cases might require tools such as a

screwdriver. However, both self-service and optional-service CRUs are safe for

removal by the customer.

Customers are responsible for replacing all self-service CRUs. Optional-assist

CRUs can be removed and installed by customers or by a Lenovo service

technician during the warranty period.

The User Guide and Hardware Installation and Replacement Guide provide

instructions for replacing self-service and optional-assist CRUs. Refer to the

following tables to determine which publication contains the instructions you

need.

The publications are available on the Lenovo Web site at http://

www.lenovo.com.

Note: Only use computer parts provided by Lenovo. Refer to Chapter 3,

“Lenovo Limited Warranty,” on page 15 for warranty information about the

CRUs for your machine type.
