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.
