iv T14s Gen 2 and X13 Gen 2 Hardware Maintenance Manual

Chapter 1. Safety information

This chapter presents following safety information that you need to be familiar with before you service a

ThinkPad notebook computer.

• “General safety” on page 1

• “Electrical safety” on page 1

• “Safety inspection guide” on page 3

• “Handling devices that are sensitive to electrostatic discharge” on page 3

• “Grounding requirements” on page 4

• “Safety notices (multilingual translations)” on page 4

General safety

Follow these rules to ensure general safety:

• Observe good housekeeping in the area of the machines during and after maintenance.

• When lifting any heavy object:

1. Ensure that you can stand safely without slipping.

2. Distribute the weight of the object equally between your feet.

3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.

4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the

muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or that you

think is too heavy for you.

• Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.

• Before you start the machine, ensure that other service technicians and the customer's personnel are not

in a hazardous position.

• Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the

machine.

• Keep your tool case away from walk areas so that other people will not trip over it.

• Do not wear loose clothing that can be trapped in the moving parts of a machine. Ensure that your sleeves

are fastened or rolled up above your elbows. If your hair is long, fasten it.

• Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, about 8

centimeters (3 inches) from the end.

• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing, because metal

objects are good electrical conductors.

• Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching springs, using

solvents, or working in any other conditions that might be hazardous to your eyes.

• After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that

is worn or defective.

• Reinstall all covers correctly before returning the machine to the customer.

• Fan louvers on the machine help to prevent overheating of internal components. Do not obstruct fan

louvers or cover them with labels or stickers.

Electrical safety

Observe the following rules when working on electrical equipment.

Important:

• Use only approved tools and test equipment. Some hand tools have handles covered with a soft material

that does not insulate you when working with live electrical currents.

• Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to

decrease electrostatic discharges (ESD). Do not use this type of mat to protect yourself from electrical

shock.

• Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical

accident occurs, you can then operate the switch or unplug the power cord quickly.

• Do not work alone under hazardous conditions or near equipment that has hazardous voltages.

• Disconnect all power before:

– Performing a mechanical inspection

– Working near power supplies

– Removing or installing main units

• Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer

to power off the wall box that supplies power to the machine, and to lock the wall box in the off position.

• If you need to work on a machine that has exposed electrical circuits, observe the following precautions:

– Ensure that another person, familiar with the power-off controls, is near you. That person must be there

to switch off the power, if necessary.

– Use only one hand when working with powered-on electrical equipment; keep the other hand in your

pocket or behind your back.

CAUTION:

An electrical shock can occur only when there is a complete circuit. By observing the above rule,

you may prevent a current from passing through your body.

– When using testers, set the controls correctly and use the approved probe leads and accessories for

that tester.

– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as

metal floor strips and machine frames.

Observe the special safety precautions when you work with very high voltages. Instructions for these

precautions are in the safety sections of maintenance information. Use extreme care when measuring high

voltages.

• Regularly inspect and maintain your electrical hand tools for safe operational condition.

• Do not use worn or broken tools and testers.

• Never assume that power has been disconnected from a circuit. First, check that it has been powered off.

• Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors,

nongrounded power extension cables, power surges, and missing safety grounds.

• Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is

conductive; such touching can cause personal injury and machine damage.

• Do not service the following parts with the power on:

– Power supply units

– Pumps

– Blowers and fans

– Motor generators

– Units similar to those listed above

This practice ensures correct grounding of the units.

• If an electrical accident occurs:

– Use caution; do not become a victim yourself.

– Switch off power.

– Send another person to get medical aid.

2T14s Gen 2 and X13 Gen 2 Hardware Maintenance Manual

Safety inspection guide

The purpose of this inspection guide is to assist you in identifying potentially unsafe conditions. As each

machine was designed and built, required safety items were installed to protect users and service

technicians from injury. This guide addresses only those items. You should use good judgment to identify

potential safety hazards due to attachment of non-ThinkPad features or options not covered by this

inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and

whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present:

• Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal

electrical shock)

• Explosive hazards, such as a damaged CRT face or a bulging capacitor

• Mechanical hazards, such as loose or missing hardware

To determine whether there are any potentially unsafe conditions, use the following checklist at the

beginning of every service task. Begin the checks with the power off, and the power cord disconnected.

Checklist:

1. Check exterior covers for damage (loose, broken, or sharp edges).

2. Turn off the computer. Disconnect the power cord.

3. Check the power cord for:

a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground

continuity for 0.1 ohm or less between the external ground pin and the frame ground.

b. The power cord should be the authorized type specified for your computer. Go to: https://

support.lenovo.com/partslookup.

c. Insulation must not be frayed or worn.

4. Check for cracked or bulging batteries.

5. Remove the cover.

6. Check for any obvious non-ThinkPad alterations. Use good judgment as to the safety of any non-

ThinkPad alterations.

7. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or

other liquids, or signs of fire or smoke damage.

8. Check for worn, frayed, or pinched cables.

9. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered

with.

Handling devices that are sensitive to electrostatic discharge

Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to

electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects.

Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the

person handling the part are all at the same charge.

Notes:

1. Use product-specific ESD procedures when they exceed the requirements noted here.

Chapter 1.Safety information 3

2. Ensure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.

When handling ESD-sensitive parts:

• Keep the parts in protective packages until they are inserted into the product.

• Avoid contact with other people.

• Wear a grounded wrist strap against your skin to eliminate static on your body.

• Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when

you are wearing a wrist strap.

• Use a grounded work mat to provide a static-free work surface. The mat is especially useful when

handling ESD-sensitive devices.

• Select a grounding system, such as those listed below, to provide protection that meets the specific

service requirement.

Note: The use of a grounding system to guard against ESD damage is desirable but not necessary.

– Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.

– When working on a double-insulated or battery-operated system, use an ESD common ground or

reference point. You can use coax or connector-outside shells on these systems.

– Use the round ground prong of the ac plug on ac-operated computers.

Grounding requirements

Electrical grounding of the computer is required for operator safety and correct system function. Proper

grounding of the electrical outlet can be verified by a certified electrician.

Chapter 2. Important service information

This chapter introduces following important service information that applies to all machine types supported

by this manual:

• “Strategy for replacing FRUs” on page 21

– “Strategy for replacing a solid-state drive” on page 21

– “Important notice for replacing a system board” on page 22

– “How to use error message” on page 22

• “Strategy for replacing FRUs for CTO, special-bid, and standard models” on page 22

– “Product definition” on page 22

– “FRU identification” on page 23

Important:

• Advise customers to contact the Lenovo Customer Support Center if they need any assistance in

obtaining or installing any software fixes, drivers, and UEFI BIOS downloads. Telephone numbers for

Lenovo Support are available at:

https://pcsupport.lenovo.com/supportphonelist

• System Disassembly/Reassembly videos that show the FRU removals or replacements for the Lenovo

authorized service technicians are available in the following support site:

https://www.lenovoservicetraining.com/ion/

Strategy for replacing FRUs

Before replacing parts:

Ensure that all software fixes, drivers, and UEFI BIOS downloads are installed before replacing any FRUs

listed in this manual.

After a system board is replaced, ensure that the latest UEFI BIOS is loaded to the system board before

completing the service action.

To download software fixes, drivers, and UEFI BIOS, go to https://support.lenovo.com and follow the

instructions on the screen.

Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs:

• If you are instructed to replace a FRU but the replacement does not correct the problem, reinstall the

original FRU before you continue.

• 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.

• 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.

Strategy for replacing a solid-state drive

Always try to run a low-level format operation before replacing a solid-state drive. This will cause all

customer data on the drive to be lost. Ensure that the customer has a current backup of the data before you

perform this task.

Attention: The drive startup sequence in the computer you are servicing might 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.

After replacing the system board, use the Maintenance Utility to bind the model type, serial number, and

Brand ID of the computer with the new system board. Refer to https://support.lenovo.com/us/en/solutions/

HT506954 for instructions on how to do that. As an alternative, you also can use the Golden Key U1 tool for

that purpose. Refer to https://support.lenovo.com/us/en/solutions/ht507251 for instructions.

Attention: When handling a system board:

• Do not drop a system board or apply any excessive force to it.

• Avoid rough handling of any kind.

• 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 might also cause false error

codes. If no error code is displayed, see whether the error symptom is listed in the section of “Symptom-to-

FRU index” on page 35.

Strategy for replacing FRUs for CTO, special-bid, and standard models

This topic provides information about the model types and FRU identification.

Product definition

This topic introduces different model types and how to identify each type.

Dynamic Configure To Order (CTO) model

This model provides the ability for a customer to configure a Lenovo solution from a Web Site, and have this

configuration sent to fulfillment, where it is built and shipped directly to the customer. The machine label and

eSupport will load these products as the 4-character MT, 4-character model, and 2-character country code.

The model is “CTO1” and the default country code is “WW” (example: 20AACTO1WW).

Special-bid model

This model is a unique configuration that has been negotiated between Lenovo and the customer. A unique

MTM consists of a 4-character MT, a 4-character model, and a numeric 2-character country code is provided

to the customer to place orders (example: 20AA000955). The country code assigned is numeric and does not

designate a specific country or region. The custom model fact sheet for the MTM indicates which country the

special bid MTM is set up for. Special-bid offering is not generally announced.

Standard model

Standard models (fixed configuration) are announced and offered to all customers. The MTM portion of the

machine label consists of a 4-character MT, a 4-character model, and an alphabetic 2-character country

code. The country code assigned is alphabetic and represents a designated country or region (example:

20AA0009UK).

Some descriptions in this chapter might not apply to your particular computer.

Before you go to the checkout guide, be sure to read the following important notes.

Important notes:

• Only certified trained personnel should service the computer.

• Before replacing any FRU, read the entire page on removing and replacing FRUs.

• When you replace FRUs, it is recommended to use new nylon-coated screws.

• Be extremely careful during such write operations as copying, saving, or formatting. Drives in the computer

that you are servicing sequence might have been altered. If you select an incorrect drive, data or programs might be

overwritten.

• Replace a FRU only with another FRU of the correct model. When you replace a FRU, ensure that the model of

the machine and the FRU part number are correct.

• A FRU should not be replaced because of a single, unreproducible failure. Single failures can occur for a variety

of reasons that have nothing to do with a hardware defect, such as cosmic radiation, ESD, or software errors.

Consider replacing a FRU only when a problem recurs. If you suspect that a FRU is defective, clear the error log and

run the test again. If the error does not recur, do not replace the FRU.

• Be careful not to replace a nondefective FRU.

What to do first

When you return a FRU, you must include the following information in the parts exchange form or parts return

form that you attach to it:

1. Name and phone number of service technician

2. Date of service

3. Date on which the machine failed

4. Date of purchase

5. Failure symptoms, error codes appearing on the display, and beep symptoms

6. Procedure index and page number in which the failing FRU was detected

7. Failing FRU name and part number

8. Machine type, model number, and serial number

9. Customer's name and address

Note: During the warranty period, the customer may be responsible for repair costs if the computer damage

was caused by misuse, accident, modification, unsuitable physical or operating environment, or improper

maintenance by the customer. Following is a list of some common items that are not covered under warranty

and some symptoms that might indicate that the system was subjected to stress beyond normal use.

Diagnosing problems

Many computer problems can be solved without outside assistance. If you experience a problem with your

computer, the first place to start is the troubleshooting information in your computer documentation. If you

suspect a software problem, see the documentation, including readme files and help information systems,

that come with the operating system or program.

Lenovo Vantage is preinstalled on your computer. It supports the hardware scan function. It combines

diagnostic tests, system information collection, security status, and support information, along with hints and

tips for optimal system performance.

Note: If you are unable to isolate and repair the problem yourself after running the program, save and print

the log files created by the program. You need the log files when you speak to a Lenovo technical support

representative.

The troubleshooting information or the diagnostic programs might tell you that you need additional or

updated device drivers or other software. You can get the latest technical information and download device

drivers and updates from the Lenovo Support Web site at:

Passwords

As many as four passwords might be needed for a ThinkPad notebook computer: the power-on password,

the NVMe password, the supervisor password, and the system management password.

If any of these passwords has been set, a prompt for it will be displayed on the screen whenever the

computer is turned on. The computer does not start until the password is entered.

Note: If only a supervisor password is set, the password prompt will not be displayed when the operating

system is started.

Power-on password

A power-on password protects the system from being turned on by an unauthorized person. The password

must be entered before the operating system can be started. For instructions on how to remove the power-

on password, see “How to remove the power-on password” on page 33.

NVMe passwords

The NVMe password prevents unauthorized access to the data on the storage drive. When an NVMe

password is set, you are prompted to type a correct password each time you try to access the storage drive.

• Single Password

When a Single NVMe password is set, the user must enter the user NVMe password to access files and

applications on the storage drive.

• Dual Password (User + Admin)

The admin NVMe password is set and used by a system administrator. It enables the administrator to

access any storage drive in a system or any computer connected in the same network. The administrator

can also assign a user NVMe password for each computer in the network. The user of the computer can

change the user NVMe password as desired, but only the administrator can remove the user NVMe

password.

When prompted to enter an NVMe password, press F1 to switch between the admin NVMe password and

user NVMe password.

Notes: The NVMe password is not available in the following situations:

• A Trusted Computing Group (TCG) Opal-compliant storage drive and a TCG Opal management software

program are installed in the computer, and the TCG Opal management software program is activated.

• For Intel models, when an eDrive storage drive is installed in the computer preinstalled with the Windows

10 operating system.

Supervisor password

The supervisor password protects the system information stored in UEFI BIOS. It provides the following

security features:

• If only a supervisor password is set, a password prompt is displayed when you try to enter the UEFI BIOS

menu. Unauthorized users cannot change most of the system configuration options in the UEFI BIOS

menu without the password.

• The system administrator can use the supervisor password to access a computer even if the user of that

computer has set a power-on password. The supervisor password overrides the power-on password.

• The system administrator can set the same supervisor password on many ThinkPad notebook computers

to make administration easier.

Attention: If the supervisor password has been forgotten and cannot be made available to the service

technician, there is no service procedure to reset the password. The system board must be replaced for a

scheduled fee.

System management password

The system management password can also protect the system information stored in UEFI BIOS like a

supervisor password, but it has lower authority by default. The system management password can be set

through the UEFI BIOS menu or through Windows Management Instrumentation (WMI) with the Lenovo

client-management interface.

You can enable the system management password to have the same authority as the supervisor password

to control security related features. To customize the authority of the system management password through

the UEFI BIOS menu:

1. Enter the UEFI BIOS menu.

Note: When you are prompted, enter the correct supervisor password if a supervisor password has

been set, or enter the correct system management password if no supervisor password has been set.

Otherwise, you cannot change the configurations in the following steps.

2. Select Security ➙ Password ➙ System Management Password Access Control.

3. Follow the on-screen instructions.

If you have set both the supervisor password and the system management password, the supervisor

password overrides the system management password. If you have set both the system management

32 T14s Gen 2 and X13 Gen 2 Hardware Maintenance Manual

password and the power-on password, the system management password overrides the power-on

password.

How to remove the power-on password

LCD-related symptoms

Important: The TFT LCD for the notebook computer contains many thin-film transistors (TFTs). The

presence of a small number of dots that are missing, discolored, or always lighted is characteristic of TFT

LCD technology, but excessive pixel problems can cause viewing concerns.

If the LCD you are servicing has two or less visible defective pixels, it should not be considered faulty.

However, if the LCD has three or more visible defective pixels, it will be deemed as defective by Lenovo and

it should be replaced.

Notes:

• This policy applies to all ThinkPad Notebooks purchased on 1 January, 2008 or later.

• Lenovo will not provide warranty replacement if the LCD is within specifications because we cannot

guarantee that any replacement LCD will have zero pixel defects.

• One pixel consists of R, G, B sub-pixels.

LCD Self Test

When you turn on the computer and the LCD goes black, run LCD Self Test to help you determine whether

the LCD functions normally.

To run LCD Self Test:

1. Ensure that the computer is connected to ac power. Then, press the power button for about seven

seconds to turn off the computer.

2. Press Fn, left Ctrl, and the power button at the same time. If the computer displays five solid colors in

sequence across the entire screen, it indicates that the LCD functions normally.

3. The test lasts for about 20 seconds and then exits automatically. You also can press the power button to

exit the test.

Intermittent problems

Intermittent system hang problems can be due to a variety of causes that have nothing to do with a hardware

defect, such as cosmic radiation, ESD, or software errors. FRU replacement should be considered only when

a problem recurs.

When analyzing an intermittent problem, do the following:

1. Run the diagnostic test for the system board in loop mode at least 10 times.

2. If no error is detected, do not replace any FRUs.

3. If any error is detected, replace the FRU shown by the FRU code. Rerun the test to verify that no more

errors exist.

Undetermined problems

If the diagnostic tests did not identify the device that has failed, if wrong devices are installed, or if the

system simply is not operating, follow these procedures to isolate the failing FRU (do not isolate FRUs that

have no defects).

• Each FRU is available for all types or models, unless otherwise specified.

• 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 https://support.lenovo.com. Click Documentation and then follow the on-

screen instructions to find the manual for your product. You might be required to return the defective 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 and FRUs:

– Self-service CRUs: Refer to parts that can be installed or replaced easily by customer themselves or by trained

service technicians at an additional cost.

– Optional-service CRUs: Refer to parts that can be installed or replaced by customers with a greater skill level.

Trained service technicians can also provide service to install or replace the parts under the type of warranty

designated for the customer’s machine.

– FRUs: Refer to parts that must be installed or replaced only by trained service technicians. If customers choose

to replace the FRUs by themselves, the product warranty might be affected.

Screw notices

Loose screws can cause a reliability problem. In the ThinkPad notebook computer, this problem is

addressed with special nylon-coated screws that have the following characteristics:

• They maintain tight connections.

• They do not easily come loose, even with shock or vibration.

• They are harder to tighten.

Do the following when you service the computer:

• Keep the screw kit in your tool bag. For the part number of the screw kit, go to:

https://support.lenovo.com/partslookup

• It is recommended to use new screws.

• It is recommended to use each screw only once.

Tighten screws as follows:

• Plastic to plastic

Turn an additional angle of 90 degrees after the screw head touches the surface of the plastic part.

• Logic card to plastic

Turn an additional angle of 180 degrees after the screw head touches the surface of the logic card.

Notes:

• Ensure that you use the correct screw. It is recommended to use new screws for replacements. If you

have a torque screwdriver, tighten all screws firmly to the torque specified in the screw information table

for each step.

• Ensure torque screwdrivers are calibrated correctly following country specifications.

Retaining serial numbers

This topic provides instructions on the following:

• “Restoring the serial number of the system unit” on page 62

• “Retaining the UUID” on page 63

Restoring the serial number of the system unit

When the computer was manufactured, the EEPROM on the system board was loaded with the serial

numbers of the system and all major components. These numbers need to remain the same throughout the

life of the computer.

If you replace the system board, you must restore the serial number of the system unit to its original value.

The serial number of the system unit is written on the label attached to the bottom of the computer.

If you cannot find the serial number of the system unit on the bottom of the computer, try the following

method to get the number:

Note: For Intel models, before you perform the operation, ensure that the UEFI/Legacy setting within the

Startup menu in the ThinkPad Setup program is set to UEFI Only.

1. Connect a USB memory key to the computer.

2. Go to https://www.lenovo.com/maintenanceutilities and follow the instructions on the screen to create a

Maintenance Key.

Note: Only an authorized Lenovo service technician can access the above Web site.

3. Restart the computer.

4. When the logo is displayed, press Esc. The ThinkPad Config Information Update Utility interface is

displayed.

62 T14s Gen 2 and X13 Gen 2 Hardware Maintenance Manual

5. Type 1 under Enter the action desired, then press Enter. The ThinkPad Serial Number Update Utility for

Asset ID screen is displayed.

6. Type 2 under Enter the action desired, then press Enter. The serial number of each device in your

computer is displayed; the serial number of the system unit is listed as follows:

20- Serial number

7. Record the serial number of the system unit.

After you replace the system board, do the following to restore the serial number of the system unit:

1. Connect the Maintenance Key to the computer.

2. When the logo is displayed, press Esc. The ThinkPad Config Information Update Utility interface is

displayed.

3. Type 1 under Enter the action desired, then press Enter. The ThinkPad Serial Number Update Utility for

Asset ID screen is displayed.

4. Type 1 under Enter the action desired, then press Enter. Then follow the instructions on the screen to

restore the serial number of the system unit.

Retaining the UUID

The Universally Unique Identifier (UUID) is a 128-bit number uniquely assigned to your computer at

production and stored in the EEPROM of your system board.

The algorithm that generates the number is designed to provide unique IDs until the year A.D. 3400. No two

computers in the world have the same number.

When you replace the system board, perform the following steps to create a new UUID for the system board

if the system board does not have a UUID:

Note: For Intel models, before you perform the operation, ensure that the UEFI/Legacy setting within the

Startup menu in the ThinkPad Setup program is set to UEFI Only.

1. Connect a USB memory key to the computer.

2. Go to https://www.lenovo.com/maintenanceutilities and follow the instructions on the screen to create a

Maintenance Key.

Note: Only an authorized Lenovo service technician can access the above Web site.

3. Restart the computer.

4. When the logo screen is displayed, press Esc. The ThinkPad Config Information Update Utility interface

is displayed.

5. Type 2 under Enter the action desired, then press Enter. The Auto UUID generation utility interface is

displayed.

6. Type y under Change UUID. OK? [Y/N], then press Enter. A new UUID is created and written. If a valid

UUID already exists, it is not overwritten.

Reading or writing the ECA information

Information on Engineering Change Announcements (ECA) is stored in the EEPROM of the system board.

The electronic storage of this information simplifies the procedure to check if the ECA has been previously

applied to a machine. The machine does not need to be disassembled to check for the ECA application.

To check what ECAs have been previously applied to the machine, use the ECA Information Read/Write

function on the LENOVO ThinkPad Hardware Maintenance Diskette or Maintenance Key.

1. Insert the latest version of LENOVO ThinkPad Hardware Maintenance Diskette or Maintenance Key, and

then restart the computer.

2. From the main menu, select 6. Set ECA Information.

Chapter 7.FRU replacement notices 63

3. To read the ECA information, select 2. Read ECA/rework number from EEPROM and follow the

instructions on the screen. To read the box build date, select 5. Read box build date from EEPROM,

and follow the instruction on the screen.

After an ECA has been applied to the machine, the EEPROM must be updated to reflect the ECA's

application. Use the latest version of LENOVO ThinkPad Hardware Maintenance Diskette or Maintenance

Key to update the EEPROM.

Note: Only the ECA number is stored in the EEPROM. The machine type of the ECA is assumed to be the

same as the machine type of the machine that had the ECA applied to it.

1. Insert the latest version of LENOVO ThinkPad Hardware Maintenance Diskette or Maintenance Key, and

then restart the computer.

2. From the main menu, select 6. Set ECA Information.

3. To write the ECA information, select 1. Write ECA/rework number from EEPROM, and follow the

instructions on the screen. To write the box build date, select 4. Write box build date from EEPROM,

and follow the instruction on the screen.

If the system board is being replaced, try to read the ECA information from the old system board and transfer

the information to the new system. If the system board is inoperable, this will not be possible.

Important notices for handling the system board:

When handling the system board, read the following:

• The system board has an accelerometer, which can be broken when several thousands of G-forces are applied.

Note: Dropping a system board from a height of as little as 6 inches so that it falls flat on a hard bench can subject

the accelerometer to as much as 6000 G's of shock.

• Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or

composite.

• Avoid rough handling of any kind.

• At every point in the process, be sure not to drop or stack the system board.

• If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or a corrugated

conductive surface.
