• 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 installs 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/support. Click User Guides & Manuals and then follow the on-screen
instructions to find 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.
ThinkPad computers 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 might include the memory module, wireless card,
keyboard, and palm rest with finger print reader and touchpad.
– 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.
