What is a CRU?

Customer replaceable units (CRUs) are parts that can be upgraded or replaced by the customer. A Lenovo

computer may contain the following types of CRUs:

Self-service CRU Parts that can be installed or replaced easily by

customer themselves or by trained service

technicians at an additional cost.

Optional-service CRU Parts that can be installed or replaced by customers

with a greater skill level. Trained service technicians

can also provide service to install or replace the

parts under the type of warranty designated for the

customer’s machine.

If you intend to install a CRU, Lenovo will ship the CRU to you. You might be required to return the defective

part that is replaced by the CRU. When return is required: (1) return instructions, a prepaid shipping label,

and a container will be included with the replacement CRU; and (2) you might be charged for the

replacement CRU if Lenovo does not receive the defective CRU within thirty (30) days of your receipt of the

replacement CRU. For full details, see the Lenovo Limited Warranty at https://www.lenovo.com/warranty/llw_
