Notes:
• Each FRU is available for all types or models, unless otherwise specied.
• 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 nd 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/support. Click User Guides & Manuals and then
follow the on-screen instructions to nd 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.

of CRUs include the ac power adapter, power cord, battery, and hard disk drive. Other self-service CRUs
depending on product design might include the wireless card, keyboard, and palm rest with nger print
reader and touch pad.
– 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 specic
CRU is visible.
