							Use the following strategy to prevent unnecessary expense for replacing and 
servicing FRUs: 
v   
 If you are instructed to replace a FRU but the replacement does not correct the 
problem, reinstall the original FRU before you continue. 
v 
 
 Some computers have both a processor board and a system board. If you are 
instructed to replace either the processor board or the system board, and 
replacing one of them does not correct the problem, reinstall that board, and 
then replace the other one. 
v 
 
 If an adapter or a device consists of more than one FRU, any of the FRUs may 
be the cause of the error. Before replacing the adapter or device, remove the 
FRUs, one by one, to see if the symptoms change. Replace only the FRU that 
changed the symptoms. 
Attention: 
 The setup configuration on the computer you are servicing may have 
been customized. Running Automatic Configuration may alter the settings. Note 
the current configuration settings (using the View Configuration option); then, 
when service has been completed, verify that those settings remain in effect. 
Strategy for replacing a hard disk drive 
Always try to run a low-level format before replacing a hard disk drive. This will 
cause all customer data on the hard disk to be lost. Be sure that the customer has a 
current backup of the data before doing this task. 
 
Attention:   The drive startup sequence in the computer you are servicing may 
have been changed. Be extremely careful during write operations such as copying, 
saving, or formatting. If you select an incorrect drive, data or programs can be 
overwritten. 
Important notice for replacing a system board 
Some components mounted on a system board are very sensitive. Improper 
handling of a system board can cause damage to those components, and may 
cause a system malfunction. 
 
Attention:   When handling a system board: 
v 
 
 Do not drop a system board or apply any excessive force to it. 
v 
 
 Avoid rough handling of any kind. 
v 
 
 Avoid bending a system board and hard pushing to prevent cracking at each 
BGA (Ball Grid Array) chipset.
How to use error message 
Use the error codes displayed on the screen to diagnose failures. If more than one 
error code is displayed, begin the diagnosis with the first error code. Whatever 
causes the first error code may also cause false error codes. If no error code is 
displayed, see whether the error symptom is listed in the Symptom-to-FRU Index 
for the computer you are servicing.

							Strategy for replacing FRUs for CTO, CMV, and GAV 
Product definition 
Dynamic Configure To Order (CTO) 
This provides the ability for a customer to configure an IBM® or a Lenovo solution 
from an eSite, and have this configuration sent to fulfillment, where it is built and 
shipped directly to the customer. The machine label, Product Entitlement 
Warehouse (PEW), eSupport, and the HMM will load these products as the 4-digit 
MT and 3-digit model, where model = “CTO” (Example: 1829-CTO). 
Custom Model Variant (CMV) 
This is a unique configuration that has been negotiated between IBM or 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. 
v   
 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). 
v 
 
 The PEW record is the 4-digit MT and 3-digit model, where model = “CTO” 
(Example: 1829-CTO). 
v 
 
 eSupport will show both the CTO and CMV machine type models (Example: 
1829-CTO and 1829-W15 will be found on the eSupport site.) 
v 
 
 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 
v 
 
 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. 
v 
 
 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). 
v 
 
 PEW can be accessed at the following We b 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. 
 
Important service information 19 
						

							v   
 Business Partners using Eclaim will access PEW when performing Entitlement 
Lookup. Business Partners will enter Loc ID, MT and Serial, and the key 
commodities will be returned in the Eclaim record under SYSTEM DETAILS. 
v 
 
 Authorized IBM Business Partners can access Eclaim at the following We b site: 
https://wca.eclaim.com
Using eSupport 
For Key Commodities (Examples - hard disk drive, system board, 
microprocessor, LCD, and memory) 
v 
 
 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). 
v 
 
 eSupport can be accessed at the following We b site: http://www.lenovo.com/
support
 
v   
 To view the key commodities, click on PA R T S INFORMATION, then PA R T S 
LOOKUP. Type in the model type and serial number. The key commodities will 
be returned in the eSupport record under PA R T S SHIPPED WITH YOUR 
SYSTEM.
For
 the Remaining FRUs (the complete list of FRUs at the MT Model level) 
v   
 eSupport can be used to view the complete list of FRUs for a machine type and 
model. 
v 
 
 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 PA R T S 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) 
Use the HMM as a back-up to PEW and eSupport to view the complete list of 
FRUs at the MT Model level.

							Important information about replacing RoHS compliant FRUs 
RoHS, The Restriction of Hazardous Substances in Electrical and Electronic 
Equipment Directive (2002/95/EC) is a European Union legal requirement 
affecting the global electronics industry. RoHS requirements must be 
implemented on Lenovo products placed on the market after June 2006. Products 
on the market before June 2006 are not required to have RoHS compliant parts. 
If the original FRU parts are non compliant, replacement parts can also be non 
compliant. In all cases if the original FRU parts are RoHS compliant, the 
replacement part must also be RoHS compliant. 
Note: RoHS and non-RoHS FRU part numbers with the same fit and function are 
identified with unique FRU part numbers. 
Lenovo plans to transition to RoHS compliance well before the implementation 
date and expects its suppliers to be ready to support Lenovo’s requirements and 
schedule in the EU. Products sold in 2005 and 2006, will contain some RoHS 
compliant FRUs. The following statement pertains to these products and any 
product Lenovo produces containing RoHS compliant FRUs. 
RoHS compliant FRUs have unique FRU part numbers. Before or after the RoHS 
implementation date, failed RoHS compliant parts must always be replaced using 
RoHS compliant FRUs, so only the FRUs identified as compliant in the system 
HMM or direct substitutions for those FRUs may be used. 
 Products marketed before June 2006 Products marketed after June 2006 
Current or original 
part 
Replacement FRU Current or original 
part 
Replacement FRU 
Non-RoHS Can be Non-RoHS Must be RoHS Must be RoHS 
Non-RoHS Can be RoHS 
Non-RoHS Can sub to RoHS 
RoHS Must be RoHS
   
Note: A direct substitution is a part with a different FRU part number that is 
automatically shipped by the distribution center at the time of the order.
