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
