Introduction

Important service information

Important

BIOS and device driver fixes are

customer-installable. The BIOS and device drivers

are posted on the customer support site

http://www.lenovo.com/think/ support

Advise customers to contact the Customer Support

Center at 800-426-7378 if they need assistance in

obtaining or installing any diskette fixes.

Customers in Canada should call the Customer

Support Center at 800-565-3344 for assistance or

download information.

Strategy for replacing FRUs

Before replacing parts

Make sure that all diskette fixes are installed before

replacing any FRUs listed in this manual.

Use the following strategy to prevent unnecessary expense

for replacing and servicing FRUs:

vIf you are instructed to replace aFRU but the

replacement does not correct the problem, reinstall

the original FRU before you continue.

vSome computers have both aprocessor 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.

vIf an adapter or adevice 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 ahard disk drive

Always try to run alow-level format before replacing ahard

disk drive.

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.

How to use error messages

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 acustomer to configure an

IBM

solution from an eSite, and have this configuration

sent to fulfillment, where it is built and shipped directly to

the customer. The machine label, PC 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 aunique configuration that has been negotiated

between IBM and the customer. Aunique 4-digit MT and

3-digit model is provided to the customer to place orders

(Example: 1829-W15). ACMV is aspecial bid offering.

Therefore, it is NOT generally announced.

vThe 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).

vThe PEW record is the 4-digit MT and 3-digit model,

where model =“CTO” (Example: 1829-CTO).

veSupport will show both the CTO and CMV machine

type models (Example: 1829-CTO and 1829-W15 will be

found on the eSupport site.)

Important service information

4MT1864/1865/2525/2526/2527/2528

vThe 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 astandard model (fixed configuration). GAVs are

announced and offered to all customers. The MTM portion

of the machine label is a4-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

vPEW is the primary source for identifying FRU part

numbers and FRU descriptions for the key commodities

for CTO, CMV and GAV products at aMT -serial

number level. An example of key commodities are hard

disk drives, system boards, microprocessors, Liquid

Crystal Displays (LCDs), and memory.

vRemember, 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).

vPEW can be accessed at the following Web site:

http://w3-3.ibm.com/pc/entitle

Click on MACHINE LOOKUP, followed by WARRANTY

INFORMATION. Input the MT and the Serial number

and the list of key commodities will be returned in the

PEW record under COMPONENT INFORMATION.

vBusiness 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.

vAuthorized IBM Business Partners can access Eclaim at

the following Web site: https://wca.eclaim.com

Using eSupport

For Key Commodities (Examples -hard disk drive,

system board, microprocessor, LCD, and memory)

Important service information

Introduction 5

veSupport can be used to view the list of key

commodities built in aparticular machine serial (this is

the same record found in PEW).

veSupport can be accessed at the following Web site:

http://www.lenovo.com/think/ support

vTo 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)

veSupport can be used to view the complete list of FRUs

for amachine type and model.

vTo 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

Use the HMM as aback-up to PEW and eSupport to view

the complete list of FRUs at the MT Model level.
