Chapter 7. CRU replacement
Customer Replaceable Units (CRUs) are parts that can be replaced by the customer. Lenovo computers
contain the following types of CRUs:
• Self-service CRUs: Refer to parts that can be replaced easily by customer themselves or by trained
service technicians at an additional cost.
• Optional-service CRUs: Refer to parts that can be replaced by customers with a greater skill level.
Trained service technicians can also provide service to replace the parts under the type of warranty
designated for the customer's machine.
If you intend on installing the CRU, Lenovo will ship the CRU to you. CRU information and replacement
instructions are shipped with your product and are available from Lenovo at any time upon request. 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
documentation at:
