Lenovo 33472YU, S230U FRU identification for CTO, CMV, and GAV products, Custom Model Variant CMV

Page 29

Custom Model Variant (CMV)

This is a unique configuration that has been negotiated between Lenovo and the customer. A unique 4-digit MT and 3-digit model is provided to the customer to place orders (Example: 1829-W15). A CMV is a special bid offering. Therefore, it is NOT generally announced.

•The MTM portion of the machine label is the 4-digit MT and 3-digit model, where model = “CTO” (Example: 1829-CTO). The PRODUCT ID portion of the machine label is the 4-digit MT and 3-digit CMV model (Example: 1829-W15).

•The PEW record is the 4-digit MT and 3-digit model, where model = “CTO” (Example: 1829-CTO).

•eSupport will show both the CTO and CMV machine type models (Example: 1829-CTO and 1829-W15 will be found on the eSupport site.)

General Announce Variant (GAV)

This is a standard model (fixed configuration). GAVs are announced and offered to all customers. The MTM portion of the machine label is a 4-digit MT and 3-digit model, where model = a “fixed part number”, not “CTO” (Example: 1829-F1U). Also, PEW, and eSupport will list these products under the same fixed model number.

FRU identification for CTO, CMV, and GAV products

There are two information resources to identify which FRUs are used to support CTO, CMV, and GAV products. These sources are PEW and eSupport.

Using PEW

•PEW is the primary source for identifying FRU part numbers and FRU descriptions for the key commodities for CTO, CMV and GAV products at a MT - serial number level. An example of key commodities are hard disk drives, system boards, microprocessors, Liquid Crystal Displays (LCDs), and memory.

•Remember, all CTO and CMV products are loaded in PEW under the 4-digit MT and 3-digit model, where model = “CTO” (Example: 1829-CTO). GAVs are loaded in PEW under the 4-digit MT and 3-digit model, where model = a “fixed part number”, not “CTO” (Example: 1829-F1U).

•PEW can be accessed at the following Web site: http://www.lenovo.com/support/site.wss/document.do?lndocid=LOOK-WARNTY

Select Warranty lookup. Input the MT and the Serial number and the list of key commodities will be returned in the PEW record under COMPONENT INFORMATION.

Using eSupport

For key commodities (examples - hard disk drive, system board, microprocessor, LCD, and memory)

eSupport can be used to view the warranty status of key commodities built in a particular machine serial (this is the same record found in PEW). eSupport can be accessed at http://www.lenovo.com/support.

To view the warranty status of the key commodities on your computer, do the following:

1.Go to http://www.lenovo.com/support.

2.Click Warranty & Services.

3.Click Check Warranty Status.

4.On the Warranty Status Lookup page, click Parts Lookup.

5.Type your machine type and serial number, and then click Submit.

For the remaining FRUs (the complete list of FRUs at the MT model level)

eSupport also can be used to view the complete list of FRUs for a machine type and model.
