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.
ThinkPad Notebooks contain the following types of CRUs:
Self-service CRUs
These CRUs unplug or are held by no more than two screws. Examples of these types of CRUs include
the ac power adapter, power cord, battery, and hard disk drive. Other Self-service CRUs depending on
product design may include the memory module, wireless card, and keyboard.
Optional-service CRUs
These CRUs are isolated parts within the computer that are concealed by an access panel that is typically
secured by more than two screws. Once the access panel is removed, the specific CRU is visible.
