• 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.)

• The HMM will have the 4-digit MT and 3-digit CTO model only (Example: 1829-CTO). Again, CMVs are

custom models and are not found in the HMM.

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, eSupport, and the HMM will list these products under the same
fixed model number.

FRU identification for CTO, CMV, and GAV products

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

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 list of key commodities built in a particular machine serial (this is the

same record found in PEW).

• eSupport can be accessed at the following Web site: http://www.lenovo.com/support

• To view the key commodities, click on PARTS INFORMATION, then PARTS LOOKUP. Type in the model

type and serial number. The key commodities will be returned in the eSupport record under PARTS
SHIPPED WITH YOUR SYSTEM.

For the Remaining FRUs (the complete list of FRUs at the MT Model level)

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

• To view the complete list of FRUs, type in the machine type and model (Example: 1829-CTO) under

QUICK PATH. Under “View by Document Type” select PARTS INFORMATION. Under “Filter by Category”
select SERVICE PARTS. Under “Parts Information by Date” select SYSTEM SERVICE PARTS. The list of
service parts by description, with applicable machine type model and FRU will be displayed.

Using the HMM

For Key Commodities (Examples - hard disk drive, system board, microprocessor, LCD, and memory)
