Strategy for replacing FRUs
Before replacing parts
Make sure that all software 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. Loading Setup
Defaults or replacing the system board may alter the
settings. Note the current configuration settings (using the
BIOS Setup Utility); 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.

Follow these rules to ensure general safety:
v
v
Observe good housekeeping in the area of the
machines during and after maintenance.
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
v
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
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
v
Keep your toolcase 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. Make sure that your sleeves
are fastened or rolled up above your elbows. If your hair
is long, fasten it.
v
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.
Do not wear jewelry, chains, metal-frame eyeglasses, or
metal fasteners for your clothing.

Fan louvers on the machine help to prevent overheating
of internal components. Do not obstruct fan louvers or
cover them with labels or stickers.
Warning
Handling the cord on this product or cords
associated with accessories sold with this product
will expose you to lead, a chemical known to the
state of California to cause cancer, and birth defects
or other reproductive harm. Wash hands after
handling.
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
v
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
v
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.
If you need to work on a machine that has exposed
electrical circuits, observe the following precautions:
Introduction 17
Download from Www.Somanuals.com. All Manuals Search And Download.
Safety information
–
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.
–
–
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
v
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.
v
v
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.
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
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.)

Safety information
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-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:
v
Electrical hazards, especially primary power (primary
voltage on the frame can cause serious or fatal
electrical shock)
v
v
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. 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-ThinkPad alterations. Use
good judgment as to the safety of any non-ThinkPad
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.

Safety information
8. 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.
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
v
Avoid contact with other people.
Wear a grounded wrist strap against your skin to
eliminate static on your body.
v
v
v
Prevent the part from touching your clothing. Most
clothing is insulative and retains a charge even when
you are wearing a wrist strap.
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.
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.

Safety information
–
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.
Laser compliance statement

v
v
Only certified trained personnel should
service the computer.
Read the entire FRU removal and replacement
page before replacing any FRU.
Use new nylon-coated screws when you
replace FRUs.
Be extremely careful during write operations
such as copying, saving, or formatting. The
drive startup sequence in the computer you are
servicing might have been changed. If you select
an incorrect drive, data or programs might be
overwritten.
v
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.
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.
What to do first
When you do return a FRU, you must include the following
information in the parts exchange form or parts return form
that you attach to it:

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, and the latest
procedure on how to do so, see “Recovery CDs” on
The Product Recovery program is in the Predesktop Area,
a section of the hard disk drive that is not displayed by
Windows Explorer.
Note: The recovery process might take up to 2 hours.
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.
To use the Product Recovery program to install your
pre-installed software, do the following:
1. If possible, save all your files to media other than your
hard disk.
2. Turn off your computer.

3. Turn on your computer. At the prompt, press the
Access IBM button. (The prompt “To interrupt normal
startup, press the blue Access IBM button” appears for
only a few seconds. You must press the Access IBM
button quickly.) The Predesktop Area appears on the
screen. Next, double-click the “Recover to factory
contents” icon. The Product Recovery program main
menu opens.
4. Select the recovery options you want, and then follow
the instructions on the screeen.
5. When the Product Recovery program finishes, your
computer will restart and begin the configuration
process.
Using the recovery CD
You can delete the Predesktop Area partition by going into
the BIOS Setup Utility (F1 at IBM Splash Screen), and
then choosing Security -> IBM Predesktop Area -->
Disabled. This will make the Predesktop Area available to
FDISK. If you choose Disabled, the following warning
appears:
Attention! If you select Disabled, the IBM Predesktop Area
will be visible and can be reclaimed by the OS. Once the
area is overwritten by OS tools, it can’t be used with
Normal or Secure again and you will need to obtain a
Recovery CD to retrieve original HDD. Please confirm that
you wish to select Disabled.
FDISK will not delete the Predesktop Area unless you do
this, because it is not visible. You would have to use
ThinkPad Maintenance Diskette to completely wipe the
drive.
To create the Predesktop Area and install the preloaded
system from the recovery CD, do the following:
To create the Predesktop Area:
1. Erase all partitions on the hard disk drive, using FDISK
or a similar application.
2. Boot with the recovery CD (and the boot diskette if
required).
3. The following message is displayed: “Your computer
originally included a Product Recovery program ...
Reinstall the Product Recovery program? (Y/N) [ ]”.
Note: If the hard disk drive contains any partition, you
do not receive this message; go to step 1.
4. Press the Y key. The Predesktop Area is created and
loaded with the Product Recovery program files.

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.

Related service information
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
v
User HDP—for the user
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.
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, neither Lenovo nor Lenovo authorized servicers
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 BIOS Setup Utility. The SVP must
be entered in order to get access to the 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 has been forgotten, do the
following:
(A) If no SVP has been set:
1. Turn off the computer.
2. Remove the battery pack.

Note: Noise from the ac adapter does not always indicate
a defect.
Checking operational charging
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:

3. If the voltage is less than +11.0 V dc, the battery pack
has been discharged.
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
The backup battery is rechargeable.
To check the backup battery, do the following:
1. Power off the computer, and unplug the ac adapter
from it.
2. Turn the computer upside down.

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
If the diagnostic tests did not identify the adapter or 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).
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
1. Turn off the computer.
2. Visually check each FRU for damage. Replace any
damaged FRU.
3. Remove or disconnect all of the following devices:
a. Non-ThinkPad devices
b. Devices attached to the port replicator
c. Printer, mouse, and other external devices
d. Battery pack
e. Hard disk drive
f. External diskette drive
g. DIMM
h. CD-ROM and diskette drive in the Ultrabay
i. PC Cards
4. Turn on the computer.
5. Determine whether the problem has been solved.
6. If the problem does not recur, reconnect the removed
devices one at a time until you find the failing FRU.
7. If the problem remains, replace the following FRUs one
at a time (do not replace a nondefective FRU):
a. System board
b. LCD assembly

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 the
ThinkPad computer, this problem is addressed with special
nylon-coated screws that have the following characteristics:
v
They maintain tight connections.
They do not easily come loose, even with shock or
vibration.
v
v
v
They are harder to tighten.
Each one 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.
Always use new screws.
v
v
Use a torque screwdriver if you have one.
Tighten screws as follows:

v
Make sure that 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 that all of the
screws are tightened firmly.
Retaining serial numbers
This section includes the following descriptions:

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 1.69 or later, 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 of each device in your computer is
displayed; the serial number of the system unit is listed as
follows:
v
20: Serial number
Write down that number.
Note: The serial number of the system unit is also written
on the label attached to the bottom of the computer.
After you have replaced the system board, restore the
serial number by doing the following:
1. Install the ThinkPad Hardware Maintenance Diskette
Version 1.69 or later 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.

FRU replacement notices
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, you must set the
UUID on the new system board as follows:
1. Install the ThinkPad Hardware Maintenance Diskette
Version 1.69 or later, 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.
Reading or writing the ECA information
Information on Engineering Change Announcements (ECA)
are 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 ThinkPad Hardware Maintenance Diskette Version 1.69
or later.
1. Insert the ThinkPad Hardware Maintenance Diskette
Version 1.69 or later, and restart the computer.
2. From the main menu, select 6. Set ECA Information.
3. To read ECA information, select 2. Read ECA/rework
number from EEPROM and follow the instruction.
4. To read 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 ThinkPad Hardware Maintenance
Diskette Version 1.69 or later to update the EEPROM.
Note: Only the ECA number is stored in the EEPROM.
The machine type of the ECA is assumed be the
same as the machine type of the machine that had
the ECA applied to it.
1. Insert the ThinkPad Hardware Maintenance Diskette
Version 1.69 or later, and restart the computer.

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.
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 given in the drawings by the numbers in
square callouts.
5. When turning a screw to replace a FRU, turn it in the
direction as given by the arrow in the drawing.
6. When removing the FRU, move it in the direction as
given 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 112.
8. When replacing a FRU, use the correct screw as
shown in the procedures.
DANGER
Before removing any FRU, turn off the computer,
unplug all power cords from electrical outlets,
remove the battery pack, and then disconnect any
interconnecting cables.
Attention: After replacing a FRU, do not turn on the
computer until you have made sure that all screws,
springs, and other small parts are in place and none are
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).
