Chapter 6. Customer Replaceable Units (CRUs)

Customer Replaceable Units (CRUs) are computer parts that can be upgraded or replaced by the customer. There are two types of CRUs: Self-serviceand Optional-service. Self-service CRUs are easy to install. They might be standalone, latched, or require a screwdriver to remove a maximum of two screws. However, Optional-service CRUs require some technical skills and in some cases might also require simple tools, such as a screwdriver. However, both Self-service and Optional-service CRUs are safe for the customer to remove.

Customers are responsible for replacing all Self-service CRUs. Optional-service CRUs can be removed and installed by customers or by a Lenovo service technician during the warranty period. Lenovo desktop computers contain both Self-service and Optional-service CRUs.

•Self-service CRUs: These CRUs unplug or are secured by no more than two screws. Examples of these types of CRUs include the keyboard, the mouse, any USB device, and the power cord. Other Self-service CRUs depending on product design might include memory modules, adapter cards, hard disk drives, and optical drives.

•Optional-service CRUs: These CRUs are isolated parts within the computer and are concealed by an access panel that is typically secured by more than two screws. Once the access panel is removed, the specific CRU is visible.

•Both types of CRUs are listed in the tables on the following page.
