• 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

manual for your product. You might be required to return the defective 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.
• Your computer contains the following types of CRUs and FRUs:
– 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 install or replace the parts under the type of
warranty designated for the customer's machine.
– FRUs: Refer to parts that must be replaced only by trained service technicians. If customers choose to
replace the FRUs by themselves, the product warranty might be affected.
