CRU statement for customers:
You can resolve some problems with your product 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. For optional-service
CRUs, you can either install the CRU yourself or you can request that a Service Provider install the CRU according to
the warranty service for your product.
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 can find a list of CRUs for your product in this
Hardware Maintenance Manual . An electronic
version of this manual can be found at http://www.lenovo.com/UserManuals . Follow the on-screen instructions to find
the manual for your product. 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. See your Lenovo Limited Warranty
documentation for full details.
ThinkPad computers contain the following types of CRUs and FRU:
–
Self-service CRUs: Refer to parts that can be installed or replaced easily by customer themselves or by trained
service technicians at an additional cost.
– Optional-service CRUs: Refer to 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.
– FRUs: Refer to parts that must be installed or replaced only by trained service technicians. If customers choose
to replace the FRUs by themselves, the product warranty might be affected.
