Lenovo Thinkpad X230s, Hardware Maintenance Manual

Page: 53 / 100

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/support. Click 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 and power cord. Other self-service CRUs depending on product
design might include the memory module, wireless card, keyboard, and palm rest with fingerprint reader and
ThinkPad trackpad.
– 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.
