Chapter 7. FRU replacement notices
External CRU statement to customers:
Some problems with your product can be resolved with a replacement part you can install yourself, called
a “Customer Replaceable Unit” or “CRU.” Some CRUs are designated as Self-service CRUs and others
are designated as Optional-service CRUs.
Installation of Self-service CRUs is your responsibility; you may
request that Lenovo installs an Optional-service CRU according to the warranty service for your product.
Where you are 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 may
find a list of CRUs in the publications that ship with your product or at http://www.lenovo.com/CRUs. You
may 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
may be charged for the replacement CRU if Lenovo does not receive the defective part within thirty (30) days
of your receipt of the replacement CRU. See your Lenovo Limited Warranty documentation for full details.
This chapter presents notices related to removing and replacing parts. Read this chapter carefully before
replacing any FRU.
