Locating FRUs and CRUs
This topic introduces the following service parts:
•
“Major FRUs and CRUs” on page 35
• “LCD FRUs and CRUs” on page 37
Notes:
• Each FRU is available for all types or models, unless otherwise specified.
• A customer replaceable unit (CRU) is identified by a single asterisk (*) or two asterisks (**) in the CRU ID column.
A single asterisk (*) means that the part is a Self-service CRU; two asterisks (**) means that the part is an
Optional-service CRU. A Letter “N” in the CRU ID column means that the part is not a CRU.
• 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 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.
Lenovo computers contain the following types of CRUs:
