Introduction

Important service information

Important

BIOS and device driver fixes are
customer-installable. The BIOS and device drivers
are posted on the IBM support site

http://www.ibm.com/pc/support

Advise customers to contact the PC Company
HelpCenter at 800-772-2227 if they need assistance
in obtaining or installing any diskette fixes.

Customers in Canada should call IBM HelpPC 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:

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 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.

Important service information

Strategy for replacing a hard-disk drive

Always try to run a low-level format before replacing a
hard-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 if the error symptom is listed
in the Symptom-to-FRU Index for the computer you are
servicing.

Safety information

Safety information

The following section presents the safety information that
you need to be familiar with before servicing an IBM
mobile computer.

General safety

Follow these rules to ensure general safety:
v Observe good housekeeping in the area of the

machines during and after maintenance.

v When lifting any heavy object:

1. Ensure 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 objects
that you think are too heavy for you.

v Do not perform any action that causes hazards to the

customer, or that makes the equipment unsafe.

v Before you start the machine, ensure that other service

representatives and the customer’s personnel are not in
a hazardous position.

v Place removed covers and other parts in a safe place,

away from all personnel, while you are servicing the
machine.

v Keep your toolcase away from walk areas so that other

people will not trip over it.

v Do not wear loose clothing that can be trapped in the

moving parts of a machine. Make sure that your sleeves
are fastened or rolled up above your elbows. If your hair
is long, fasten it.

v Insert the ends of your necktie or scarf inside clothing or

fasten it with a nonconductive clip, approximately 8
centimeters (3 inches) from the end.

v Do not wear jewelry, chains, metal-frame eyeglasses, or

metal fasteners for your clothing.
Attention: Metal objects are good electrical

conductors.

v 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.

Introduction 15

Safety information

v After service, reinstall all safety shields, guards, labels,

and ground wires. Replace any safety device that is
worn or defective.

v Reinstall all covers correctly before returning the

machine to the customer.

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. Do not use this
type of mat to protect yourself from electrical shock.

v 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.

v Do not work alone under hazardous conditions or near

equipment that has hazardous voltages.

v Disconnect all power before:

– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units

v 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.

v 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.
Attention: Another 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.

Attention: 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.

16 ThinkPad T30 (MT 2366, 2367)

Safety information

– 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; these instructions are in the
safety sections of maintenance information. Use
extreme care when measuring high voltages.

v Regularly inspect and maintain your electrical hand tools

for safe operational condition.

v Do not use worn or broken tools and testers.
v Never assume that power has been disconnected from

a circuit. First, check that it has been powered off.

v 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.

v 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.

v Do not service the following parts with the power on

when they are removed from their normal operating
places in a machine:

– Power supply units
– Pumps
– Blowers and fans
– Motor generators

and similar units. (This practice ensures correct
grounding of the units.)

v If an electrical accident occurs:

– Use caution; do not become a victim yourself.
– Switch off power.
– Send another person to get medical aid.

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 personnel from injury.
This guide addresses only those items. You should use
good judgment to identify potential safety hazards due to
attachment of non-IBM features or options not covered by
this inspection guide.

Introduction 17

Safety information

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:

v Electrical hazards, especially primary power (primary

voltage on the frame can cause serious or fatal
electrical shock)

v Explosive hazards, such as a damaged CRT face or a

bulging capacitor

v 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. Power-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 frame ground.

b. The power cord should be the type specified in the

parts list.

c. Insulation must not be frayed or worn.

4. Remove the cover.

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

6. 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.

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

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

Handling devices that are sensitive to electorostatic 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

18 ThinkPad T30 (MT 2366, 2367)

Safety information

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.

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

When handling ESD-sensitive parts:
v Keep the parts in protective packages until they are

inserted into the product.

v Avoid contact with other people.
v Wear a grounded wrist strap against your skin to

eliminate static on your body.

v Prevent the part from touching your clothing. Most

clothing is insulative and retains a charge even when
you are wearing a wrist strap.

v Use the black side of a grounded work mat to provide a

static-free work surface. The mat is especially useful
when handling ESD-sensitive devices.

v 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 is desirable but
not required to protect against ESD damage.

– Attach the ESD ground clip to any frame ground,

ground braid, or green-wire ground.

– Use an ESD common ground or reference point

when working on a double-insulated or
battery-operated system. 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.

General descriptions

This chapter includes descriptions for any ThinkPad model
that has the PC-Doctor DOS diagnostics program. Some
descriptions might not apply to your particular computer.

Read this first

Before you go to the checkout guide, be sure to read this
section.

Important notes

v Only certified trained personnel should

service the computer.

v Read the entire FRU removal and replacement

page before replacing any FRU.

v Use new nylon-coated screws when you

replace FRUs.

v 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.

v Replace FRUs only for the correct model.

When you replace a FRU, make sure the model
of the machine and the FRU part number are
correct by referring to the FRU parts list.

v 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, electrostatic discharge, 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.

v Be careful not to replace a nondefective FRU.

Restoring the preloaded system

If the data on a hard-disk drive is damaged or accidentally
erased, you can restore the software that was shipped with
the computer. This software includes the pre-installed
operating system, applications, and device drivers.

To restore the pre-installed software, you can use either
the Product Recovery program or a recovery CD.

Ordering the recovery CD

When the hard-disk drive is replaced because of a
failure, no Product Recovery program is on the new
hard disk. In this case, you must use the Product
Recovery CD for the computer. Order the recovery
CD and the hard-disk drive at the same time so that
you can recover the new hard-disk drive with the
pre-installed software when they arrive. For
information on which CD to order, see “Recovery
CDs” on page 151

The Product Recovery program is in the service partition, a
section of the hard-disk drive that is not displayed by
Windows Explorer.

Attention: All of the files on the primary hard-disk
partition (usually drive C) will be lost in the recovery
process. Be sure to back up copies of the files you have
saved on your drive C before you begin.

Creating a Recovery Repair diskette

If the operating system cannot boot normally, or if you
cannot get access to the Product Recovery program, you
can use the Recovery Repair diskette to boot the
computer. Make a Recovery Repair diskette and save it for
future use. To make a Recovery Repair diskette, do the
following:

1. Shut down and restart the computer.

Passwords

As many as three passwords may be needed for any
ThinkPad computer: the power-on password (POP), the
hard-disk password (HDP), and the supervisor password
(SVP).

If any of these passwords has been set, a prompt for it
appears on the screen whenever the computer is turned
on. The computer does not start until the password is
entered.

Exception: If only an SVP is installed, the password

prompt does not appear when the operating
system is booted.

Power-on password:

A power-on password (POP) protects the system from
being powered on by an unauthorized person. The
password must be entered before an operating system can
be booted.

Hard-disk password:

There are two hard-disk passwords (HDPs):

v User HDP—for the user
v Master HDP—for the system administrator, who can use

it to get access to the hard disk even if the user has
changed the user HDP

Note: There are two modes for the HDP: User only and

Master + User. The Master + User mode requires

two HDPs; the system administrator enters both in
the same operation. The system administrator then
provides the user HDP to the system user.

28 ThinkPad T30 (MT 2366, 2367)

Related service information

Attention: If the user HDP has been forgotten, check
whether a master HDP has been set. If it has, it can be
used for access to the hard-disk drive. If no master HDP is
available, IBM does not provide any services to reset
either the user or the master HDP, or to recover data from
the hard-disk drive. The hard-disk drive can be replaced
for a scheduled fee.

Supervisor password:

A supervisor password (SVP) protects the system
information stored in the IBM BIOS Setup Utility. The SVP
must be entered in order to get access to the IBM BIOS
Setup Utility and make changes to system configuration
settings.

Attention: If the SVP has been forgotten and cannot be
made available to the servicer, there is no service
procedure to reset the password. The system board must
be replaced for a scheduled fee.

How to remove the power-on password

To remove a POP that you have forgotten, do the
following:

(A) If no SVP has been set:

1. Turn off the computer.

2. Remove the battery pack.
For how to remove the battery pack, see “1010 Battery

pack” on page 61.

3. Remove the backup battery.
For how to remove the backup battery, see “1050

Backup battery” on page 67.

4. Turn on the computer and wait until the POST ends.
After the POST ends, the password prompt does not

appear. The POP has been removed.

5. Reinstall the backup battery and the battery pack.

(B) If an SVP has been set and is known by the servicer:

1. Turn on the computer by pressing and holding F1.

2. Enter the SVP. The IBM BIOS Setup Utility menu
appears.

3. Select Password, using the cursor keys to move down
the menu.

removed.

Power management

To reduce power consumption, the computer has three
power management modes: screen blank, standby, and
hibernation.

Notes

v Screen blank mode is called standby mode in

Windows NT.

v Standby mode is called suspend mode in

Windows NT.

Screen blank mode

Screen blank mode has three variants, as follows:

1. If you press Fn+F3, or the time set on the “LCD off
timer” in IBM BIOS Setup Utility expires,

v The LCD backlight turns off.
v The hard-disk drive motor stops.
v The speaker is muted.

2. If you are using the ACPI operating system and you
press Fn+F3,
v The LCD backlight turns off.

30 ThinkPad T30 (MT 2366, 2367)

Related service information

v The hard-disk drive motor stops.

3. If the time set on the “Turn off monitor” timer in the
operating system expires,
v The LCD backlight turns off.

To end screen blank mode and resume normal operation,
press any key.

Standby mode

When the computer enters standby mode, the following
events occur in addition to what occurs in screen blank
mode:

v The LCD is powered off.
v The hard-disk drive is powered off.
v The CPU stops.

To enter standby mode, press Fn+F4.
Note: You can change the action of Fn+F4, if you are

using the ACPI operating system.

In certain circumstances, the computer goes into standby
mode automatically:

v If a “suspend time” has been set on the timer, and the

user does not do any operation with the keyboard, the
TrackPoint, the hard disk, the parallel connector, or the
diskette drive within that time.

v If the battery indicator blinks orange, indicating that the

battery power is low. (Alternatively, if Hibernate when
battery becomes low has been selected in the “Power
Management Properties” window, the computer goes
into hibernation mode.)

Note for the APM operating system:

Even if you do not set the low-battery alarm, the charge
indicator notifies you when the battery is low, and then the
computer enters the power-saving mode automatically.
This default low-battery behavior is independent of the
operating system; so if you have set the low-battery alarm,
the computer may not do what you specified. It chooses
either your setting or the default setting, whichever is
appropriate.

If you are using the ACPI operating system, only the
low-battery alarm is available.

To cause the computer to return from standby mode and
resume operation, do one of the following:

v Press the Fn key.
v Open the LCD cover (only if you are using Windows Me

and you entered standby mode by closing the LCD
cover.)

General descriptions 31

Related service information

v Turn on the power switch.
Also, the computer automatically returns from standby
mode and resumes operation in either of the following
events:

v The ring indicator (RI) is signaled by a serial device or a

PC Card device (Windows 2000 does not support the
ring indicator (RI) resume by PC Card device.)

v The time set on the resume timer elapses. In Windows

98, the Scheduled Tasks setting takes priority over the
Resume on timer selection in the “Power Management
Properties” window.

Note: The computer does not accept any input

immediately after it enters standby mode. Wait a
few seconds before taking any action to reenter
operation mode.

Hibernation mode

Note for Windows NT

If you are using Windows NT in NTFS format, you
cannot create a hibernation file. If you want to use
hibernation mode, you will need to reinstall Windows
NT with FAT format.

Note for OS/2

If you are using OS/2 in the default format, HPFS,
you cannot create a hibernation file. If you want to
use hibernation mode, you will need to reinstall
OS/2 with FAT format.

In hibernation mode, the following occurs:
v The system status, RAM, VRAM, and setup data are

stored on the hard disk.

v The system is powered off.
Note: If the computer enters the hibernation mode while it

is docked to the docking station, do not undock it
from the docking station before resuming normal
operation. If you do undock it and then try to
resume normal operation, you will get an error
message, and you will have to restart the system.

To cause the computer to enter hibernation mode, do any
of the following:

v Press the Fn+F12 keys.
v If you are using the APM operating system and have set

the mode to Power switch mode [Hibernation], turn
off the power switch.

32 ThinkPad T30 (MT 2366, 2367)

Related service information

v If you are using the ACPI operating system and have

defined one of the following actions as the event that
causes the system to go into hibernation mode, perform
that action.

– Closing the lid.
– Pressing the power button.
– Pressing Fn+F4 keys.

Also, the computer goes into hibernation mode
automatically in either of the following conditions:

v If a “hibernation time” has been set on the timer, and the

user does not do any operation with the keyboard, the
TrackPoint, the hard-disk drive, the parallel connector, or
the diskette drive within that time.

v If the timer conditions are satisfied in suspend mode.
v If you are using the APM operating system and have set

the mode to Hibernate when battery becomes low,
and the battery charge becomes critically low.

When the power is turned on, the computer returns from
hibernation mode and resumes operation. The hibernation
file in the boot record on the hard-disk drive is read, and
system status is restored from the hard-disk drive.

To check whether the battery charges properly during
operation, use a discharged battery pack or a battery pack
that has less than 50% of the total power remaining when
installed in the computer.

Perform operational charging. If the battery status indicator
or icon does not turn on, remove the battery pack and let it
return to room temperature. Reinstall the battery pack. If
the charge indicator or icon still does not turn on, replace
the battery pack.

If the charge indicator still does not turn on, replace the
system board. Then reinstall the battery pack. If it is still
not charged, go to the next section.

Checking the battery pack

Battery charging does not start until the Power Meter
shows that less than 95% of the total power remains;
under this condition the battery pack can charge to 100%
of its capacity. This protects the battery pack from being
overcharged or from having a shortened life.

To check the status of your battery, move your cursor to
the Power Meter icon in the icon tray of the Windows
taskbar and wait for a moment (but do not click), and the
percentage of battery power remaining is displayed. To get
detailed information about the battery, double-click the
Power Meter icon.

Note: If the battery pack becomes hot, it may not be able

to charge. Remove it from the computer and leave it
at room temperature for a while. After it cools down,
reinstall and recharge it.

To check the battery pack, do the following:

1. Power off the computer.

2. Remove the battery pack and measure the voltage
between battery terminals 1 (+) and 5 (−). See the
following figure:

Terminal Voltage (V dc)

1 + 0 to + 12.6

1(+)

4

5(-)

3. If the voltage is less than +11.0 V dc, the battery pack
has been discharged.

5 Ground (−)

Checkout guide

Note: Recharging will take at least 3 hours, even if the

indicator does not turn on.

If the voltage is still less than +11.0 V dc after
recharging, replace the battery.

4. If the voltage is more than +11.0 V dc, measure the
resistance between battery terminals 4 and 5. The
resistance must be 4 to 30 K .

If the resistance is not correct, replace the battery
pack. If the resistance is correct, replace the system
board.

Checking the backup battery

Do the following:

1. Power off the computer, and unplug the ac adapter
from it.

2. Turn the computer upside down.

3. Remove the battery pack (see “1010 Battery pack” on
page 61).

4. Remove the backup battery (see “Checking the battery
pack” on page 38).

5. Measure the voltage of the backup battery. See the
following figure.

Red (+)

Wire Voltage (V dc)

Red +2.5 to +3.2

Black (-)

v If the voltage is correct, replace the system board.
v If the voltage is not correct, replace the backup battery.

replacement, replace the system board.

Symptom-to-FRU index

Symptom-to-FRU index

The symptom-to-FRU index in this section lists symptoms
and errors and their possible causes. The most likely
cause is listed first, in boldface type.

Note: Do the FRU replacement or other actions in the

sequence shown in the column headed “FRU or
action, in sequence.” If replacing a FRU does not
solve the problem, put the original part back in the
computer. Do not replace a nondefective FRU.

This index can also help you determine, during regular
servicing, what FRUs are likely to need to be replaced
next.

A numeric error is displayed for each error detected in
POST or system operation. In the displays, n can be any
number.

If no numeric code is displayed, check the narrative
descriptions of symptoms. If the symptom is not described
there, go to “Intermittent problems” on page 56.

LCD-related symptoms

Important

The TFT LCD for the notebook computer contains
many thin-film transistors (TFTs). 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. The LCD should be replaced if the
number of missing, discolored, or lighted dots in any
background is:
v XGA: 8 or more bright dots, 8 or more dark dots,

or a total of 9 or more bright and dark dots.

v SXGA+: 11 or more bright dots, 13 or more dark

dots, or a total of 16 or more bright and dark
dots.

Note: A bright dot means a pixel is always on

(white or color.) A dark dot means a pixel is
always off (black color.)

Symptom or error FRU or action, in sequence

No beep, power-on indicator
on, and a blank LCD during
POST.

Symptom-to-FRU index

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, electrostatic discharge, 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

You are here because the diagnostic tests did not identify
which adapter or device failed, wrong devices are installed,
a short circuit is suspected, or the system is inoperative.
Follow these procedures to isolate the failing FRU (do not
isolate FRUs that have no defects).

Verify that all attached devices are supported by the
computer.

Verify that the power supply being used at the time of the
failure is operating correctly. (See “Power system

FRU replacement notices

FRU replacement notices

This section contains notices related to removing and
replacing parts. Read this section carefully before replacing
any FRU.

Screw notices

Loose screws can cause a reliability problem. In IBM
ThinkPad computer, this problem is addressed with special
nylon-coated screws that have the following characteristics:

v They maintain tight connections.
v They do not easily come loose, even with shock or

vibration.

v They are harder to tighten.
v They should be used only once.

Do the following when you service this machine:
v Keep the screw kit (for the P/N, see “Miscellaneous

parts” on page 153) in your tool bag.

v Always use new screws.
v Use a torque screwdriver if you have one.

Tighten screws as follows:

v Plastic to plastic

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

90 degrees more

(Cross-section)

v Logic card to plastic

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

180 degrees more

(Cross-section)

v Torque driver

If you have a torque driver, refer to the “Torque” column
for each step.

ThinkPad T30 57

FRU replacement notices

v Make sure you use the correct screw. If you have a

torque screwdriver, tighten all screws firmly to the torque
shown in the table. Never use a screw that you

removed. Use a new one. Make sure the screws are
tightened firmly.

Retaining serial numbers

This section includes the following descriptions:

v “Restoring the serial number of the system unit”
v “Retaining the UUID”

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.

Before replacing the system board, save the original serial
number by doing the following:

1. Install the ThinkPad hardware maintenance diskette
version 1.62, and restart the computer.

2. From the main menu, select 1. Set System
Identification.

3. Select 2. Read S/N data from EEPROM.

The serial number for each device is displayed. Write
down the serial number of the system unit, designated as
follows:

20: System unit serial number

After you have replaced the system board, restore the
serial number by doing the following:

1. Install the ThinkPad hardware maintenance diskette
version 1.62 and restart the computer.

2. From the main menu, select 1. Set System
Identification.

3. Select 1. Add S/N data from EEPROM.
Follow the instructions on the screen.

Note: The serial number of the system unit is written on

the label attached on the bottom of the computer.

Retaining the UUID

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

58 ThinkPad T30 (MT 2366, 2367)

FRU replacement notices

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, you must set the
UUID on the new system board as follows:

1. Install the ThinkPad hardware maintenance diskette
version 1.62, and restart the computer.

2. From the main menu, select 4. Assign UUID.
A new UUID is created and written. If a valid UUID

already exists, it is not overwritten.

Removing and replacing a FRU

Removing and replacing a FRU

This section presents directions and drawings for use in
removing and replacing a FRU. Be sure to observe the
following general rules:

1. Do not try to service any computer unless you have
been trained and certified. An untrained person runs
the risk of damaging parts.

2. Before replacing any FRU, review “FRU replacement
notices” on page 57.

3. Begin by removing any FRUs that have to be removed
before the failing FRU. Any such FRUs are listed at the
top of the page. Remove them in the order in which
they are listed.

4. Follow the correct sequence in the steps for removing
the FRU, as indicated in the drawings by the numbers
in square callouts.

5. When turning a screw to replace a FRU, turn it in the
direction indicated by the arrow in the drawing.

6. When removing the FRU, move it in the direction
indicated by the arrow in the drawing.

7. To put the new FRU in place, reverse the removal
procedure and follow any notes that pertain to
replacement. For information about connecting and
arranging internal cables, see “Locations” on page 130.

8. When replacing a FRU, use the correct screw as
shown in the procedures.

DANGER

Before removing any FRU, power off the computer,
unplug all power cords from electrical outlets,
remove the battery pack, and then disconnect any
interconnecting cables.

Attention: Before the computer is powered on after FRU

replacement, make sure that all screws, springs, and other
small parts are in place and are not loose inside the
computer. Verify this by shaking the computer gently and
listening for rattling sounds. Metallic parts or metal flakes
can cause electrical short circuits.

Attention: The system board is sensitive to, and can be
damaged by, electrostatic discharge. Before touching it,
establish personal grounding by touching a ground point
with one hand or by using an electrostatic discharge (ESD)
strap (P/N 6405959).
