Chapter 10. Replacing devices

This chapter provides instructions on how to install or replace hardware for your computer.

Customer Replaceable Units

Customer Replaceable Units (CRUs) are parts that can be upgraded or replaced by the customer. ThinkPad

computers contain the following types of CRUs:

• 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.

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

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 at
