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. Make sure 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.
v Do not perform any action that causes hazards to the customer, or that makes
the equipment unsafe.
v Before you start the machine, make sure 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, about 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.
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.
v 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. 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.
– 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.

v
v
v

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.

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-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 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:

4.
5.

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 type specified in the parts list.
c. Insulation must not be frayed or worn.
Check for cracked or bulging batteries.
Remove the cover.
Check for any obvious non-ThinkPad alterations. Use good judgment as to the
safety of any non-ThinkPad alterations.
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.
Check for worn, frayed, or pinched cables.
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 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 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.

Important:
BIOS and device driver fixes are customer-installable. The BIOS and device
drivers are posted on the customer support site http://www.lenovo.com/support
Advise customers to contact the Customer Support Center at 800-426-7378 if they
need assistance in obtaining or installing any software fixes, drivers, and BIOS
downloads.
Customers in Canada should call the Customer Support Center at 800-565-3344
for assistance or download information.

Strategy for replacing FRUs
Before replacing parts:
Make sure that all software fixes, drivers, and BIOS downloads are installed
before replacing any FRUs listed in this manual.
After a system board is replaced, ensure that the latest BIOS is loaded to the
system board before completing the service action.
To download software fixes, drivers, and BIOS, do as follows:
1. Go to http://www.lenovo.com/support
2. Enter the product number of the computer or press Auto-detect button on the
screen.
3. Select Downloads and drivers.
4. Follow the directions on the screen and install the necessary software.

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.

© Copyright Lenovo 2007, 2008

17

v Some computers have both a processor board and a system board. If you are
instructed to replace either the processor board or the system board, and
replacing one of them does not correct the problem, reinstall that board, and
then replace the other one.
v If an adapter or a device consists of more than one FRU, any of the FRUs may
be the cause of the error. Before replacing the adapter or device, remove the
FRUs, one by one, to see if the symptoms change. Replace only the FRU that
changed the symptoms.
Attention: The setup configuration on the computer you are servicing may have
been customized. Running Automatic Configuration may alter the settings. Note
the current configuration settings (using the View Configuration option); then,
when service has been completed, verify that those settings remain in effect.

Strategy for replacing a hard disk drive
Always try to run a low-level format before replacing a hard disk drive. This will
cause all customer data on the hard disk to be lost. Be sure that the customer has a
current backup of the data before doing this task.
Attention: The drive startup sequence in the computer you are servicing may
have been changed. Be extremely careful during write operations such as copying,
saving, or formatting. If you select an incorrect drive, data or programs can be
overwritten.

Important notice for replacing a system board
Some components mounted on a system board are very sensitive. Improper
handling of a system board can cause damage to those components, and may
cause a system malfunction.
Attention: When handling a system board:
v Do not drop a system board or apply any excessive force to it.
v Avoid rough handling of any kind.
v Avoid bending a system board and hard pushing to prevent cracking at each
BGA (Ball Grid Array) chipset.

How to use error message
Use the error codes displayed on the screen to diagnose failures. If more than one
error code is displayed, begin the diagnosis with the first error code. Whatever
causes the first error code may also cause false error codes. If no error code is
displayed, see whether the error symptom is listed in the Symptom-to-FRU Index
for the computer you are servicing.

Strategy for replacing FRUs for CTO, CMV, and GAV
Product definition
Dynamic Configure To Order (CTO)
This provides the ability for a customer to configure an IBM® or a Lenovo™
solution from an eSite, and have this configuration sent to fulfillment, where it is
built and shipped directly to the customer. The machine label, Product Entitlement
Warehouse (PEW), eSupport, and the HMM will load these products as the 4-digit
MT and 3-digit model, where model = “CTO” (Example: 1829-CTO).

Custom Model Variant (CMV)
This is a unique configuration that has been negotiated between IBM or Lenovo
and the customer. A unique 4-digit MT and 3-digit model is provided to the
customer to place orders (Example: 1829-W15). A CMV is a special bid offering.
Therefore, it is NOT generally announced.
v The MTM portion of the machine label is the 4-digit MT and 3-digit model,
where model = “CTO” (Example: 1829-CTO). The PRODUCT ID portion of the
machine label is the 4-digit MT and 3-digit CMV model (Example: 1829-W15).
v The PEW record is the 4-digit MT and 3-digit model, where model = “CTO”
(Example: 1829-CTO).
v eSupport will show both the CTO and CMV machine type models (Example:
1829-CTO and 1829-W15 will be found on the eSupport site.)
v The HMM will have the 4-digit MT and 3-digit CTO model only (Example:
1829-CTO). Again, CMVs are custom models and are not found in the HMM.

General Announce Variant (GAV)
This is a standard model (fixed configuration). GAVs are announced and offered to
all customers. The MTM portion of the machine label is a 4-digit MT and 3-digit
model, where model = a “fixed part number”, not “CTO” (Example: 1829-F1U).
Also, PEW, eSupport, and the HMM will list these products under the same fixed
model number.

FRU identification for CTO, CMV, and GAV products
There are three information resources to identify which FRUs are used to support
CTO, CMV, and GAV products. These sources are PEW, eSupport, and the HMM.

Using PEW
v PEW is the primary source for identifying FRU part numbers and FRU
descriptions for the key commodities for CTO, CMV and GAV products at a MT
- serial number level. An example of key commodities are hard disk drives,
system boards, microprocessors, Liquid Crystal Displays (LCDs), and memory.
v Remember, all CTO and CMV products are loaded in PEW under the 4-digit MT
and 3-digit model, where model = “CTO” (Example: 1829-CTO). GAVs are
loaded in PEW under the 4-digit MT and 3-digit model, where model = a “fixed
part number”, not “CTO” (Example: 1829-F1U).
v PEW can be accessed at the following Web site: http://w3-3.ibm.com/pc/

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

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 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 7 (-). See the following figure:

1(+) 2(+)

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 5 and 7. 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.

become available, they will be posted on http://www.lenovo.com/spm

Restoring the factory contents by using Product Recovery discs
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 recovery discs for
the computer. Order the recovery discs 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 discs to order, see “Recovery discs” on page
156.
To install the factory contents by using Product Recovery discs, do the following:

Note: Recovery takes several hours. The length of time depends on the method
you use. If you use recovery discs, recovery takes at least five hours.

1. Insert the Rescue and Recovery Disk1 of 1 into the optical drive, then restart
the computer. This will take several minutes.
2. When the “Welcome to Rescue and Recovery” screen is displayed, press
Continue. In the Rescue and Recovery menu, select Restore Your System. A
message giving a warning that USB devices used in recovery must be
connected when the computer is turned on appears. Click OK.
3. “Restore Your System” window appears. Select Restore my hard drive to the
original factory state, and click Next. A warning appears, click Yes. Then next
menu appears. Select I do not want to save any files and click Next. Following
menu appears with a warning, select Next. A warning appears not to power
down the computer during the recovery process. Click OK. One more warning
appears saying that recovery is intended only for unrecoverable system
problems. Click OK.
4. The Terms and Conditions window appears, select I accept these terms and
conditions and press OK. Previous menus may remain on the screen, but the
Predesktop installer begins copying files. When this completes, the computer
will restart and a window will ask you to insert a Product Recovery
Supplemental Disk, if you have one. Press No.

5. You will then be prompted to insert Product Recovery Disk 1 into the optical
drive. Insert the Product Recovery Disk 1 into the optical drive, and press OK.
In similar fashion, you will be prompted to insert the remaining recovery discs
until all the files are copied.
6. After all the files are copied, the computer will restart and return to the
“Welcome to Rescue and Recovery” screen where a window “Recovering your
system, this may take several minutes” appears and .IMZ files are processed.
A total progress bar allows you to audit this process, which will take about 8
minutes. The final recovery disc may be safely removed during this time, but
may also be left in the optical drive since it is not bootable.
7. You will then be prompted to restart the computer. Select Yes. A warning
window appears, giving you one last chance to stop the restart, but disappears
automatically after about 5 seconds. File processing continues in DOS full
screen mode for about two minutes and the computer restarts to the Windows
desktop. No user intervention is required (and should be avoided) after this
point.
8. Windows setup continues on the desktop and DOS window for IBM system
setup, with progress measured by a Factory Preinstallation window on the right
side of the screen. The processes updating installed softwares.
A warning that antivirus software is not installed appears repeatedly in the
system tray, but this should be ignored.The entire process at desktop takes
about 25 minutes.
9. Then the computer restarts, does some more DOS full screen processing, and
restarts again to a Windows desktop where factory preinstallation continues for
about 12 more minutes, another restart to a DOS screen and then back to the
Windows splash screen and back to the desktop for more preinstallation.
This lasts about 10 more minutes and the computer restarts to do NTFS
conversion and then restarts to the OOBE (Out of Box Experience)
environment.

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. For how to remove the POP, see “How to remove the power-on
password” on page 35.

ThinkPad T61 and T61p (14.1-inch) Hardware Maintenance Manual

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.
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.
For how to remove the POP, see “How to remove the hard-disk password” on
page 36.

Supervisor password
A supervisor password (SVP) protects the system information stored in the BIOS
Setup Utility. The user must enter the SVP in order to get access to the BIOS Setup
Utility and change the system configuration.
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 62.
3. Remove the backup battery.
For how to remove the backup battery, see “1100 Backup battery” on page 80.
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; then, while the “To interrupt normal startup, press the
blue ThinkVantage button” message is displayed at the lower-left of the screen,
press the ThinkVantage® button. The Rescue and Recovery screen opens.

ThinkPad T61 and T61p (14.1-inch) Hardware Maintenance Manual

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

Screen blank mode
If the time set on the “Turn off monitor” timer in the operating system expires, the
LCD backlight turns off.
To put the computer into screen blank mode, press the ThinkVantage button and
use the ThinkVantage Productivity Center.
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: If you are using the ACPI operating system, you can change the action of
Fn+F4.
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.
v Turn on the power switch.
Also, in either of the following events, the computer automatically returns from
standby mode and resumes operation:
Related service information

37

v The ring indicator (RI) is signaled by a serial device or a PC Card device.
v The time set on the resume timer elapses.
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
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
ThinkPad Advanced Dock or ThinkPad Advanced Mini Dock, do not undock it
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.
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 if 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.

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 as follows:

Notes:
v Lenovo will not provide replacement if the LCD is within specification as we
cannot guarantee that any replacement LCD will have zero pixel defects.
v A bright dot means a pixel is always on (white or color.)
v A dark dot means a pixel is always off (black color.)
v One pixel consists of R, G, B sub-pixels.

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 checkout” on page 30.)
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 or optical drive
g. DIMM
h. Optical disk or diskette in the internal drive
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
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.
v They do not easily come loose, even with shock or vibration.
v They are harder to tighten.
v 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.
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.
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.
v Ensure torque screw drivers are calibrated correctly following country
specifications.

Retaining serial numbers
This section includes the following descriptions:
v “Restoring the serial number of the system unit”
v “Retaining the UUID”
v “Reading or writing the ECA information” on page 60

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 1.73 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 1.73 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.

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 1.73 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.

ThinkPad T61 and T61p (14.1-inch)

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 1.73 or later.
1. Insert the ThinkPad Hardware Maintenance Diskette Version 1.73 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 1.73 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 1.73 or later, and
restart the computer.
2. From the main menu, select 6. Set ECA Information.
3. To write ECA information, select 1. Write ECA/rework number from EEPROM,
and follow the instruction.
4. To write 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, bear the following in mind.
v The system board has an accelerometer, which can be broken by applying
several thousands of G-forces.
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 6,000 G’s
of shock.
v Be careful not to drop the system board on a bench top that has a hard
surface, such as metal, wood, or composite.
v If a system board is dropped, you must test it, using PC-Doctor for DOS, to
make sure that the HDD Active Protection still functions (see below).
Note: If the test shows that HDD Active Protection is not functioning, be sure
to document the drop in any reject report, and replace the system board.
v Avoid rough handling of any kind.
v At every point in the process, be sure not to drop or stack the system board.
v If you put a system board down, be sure to put it only on a padded surface
such as an ESD mat or conductive corrugated material.
After replacing the system board, run PC-Doctor for DOS to make sure that
HDD Active Protection still functions. The procedure is as follows:
1. Place the computer on a horizontal surface.
2. Run Diagnostics --> ThinkPad Devices --> HDD Active Protection Test.
Attention:: Do not apply physical shock to the computer while the test is
running.

v “LCD FRUs” on page 146
v “Keyboard” on page 152
v “Miscellaneous parts” on page 153
v “AC adapters” on page 154
v “Power cords” on page 155
v “Recovery discs” on page 156
v “Common service tools” on page 165

Notes:
v Each FRU is available for all types or models, unless specific types or models
are specified.
v FRU with specific models listed and described as xxU (where U is an example
of a country designator) should be used for all models ending in U.
v FRU with specific models listed and described as 3Dx (where 3D is an
example of a unique configuration) should be used for all of these models,
unless specific country or region designator is specified.
v A CRU (customer replaceable unit) is identified by a single asterisk (*) or two
asterisks (**) in the CRU ID column. An N in the CRU ID column means the
part is not a CRU. A single asterisk (*) means the part is an External CRU; two
asterisks (**) means the part is an Internal CRU.
ThinkPad computers contain the following types of the external CRUs:
External CRUs (pluggable)
These CRUs unplug from the computer. Examples of these types of
CRUs include an ac adapter, an external keyboard, a mouse, a power
cord, a port replicator, a USB device, and an external bay device
adapter.
External CRUs with latches
These CRUs have a latch to help you to remove and replace the part.
Examples of these types of CRUs include a battery pack, an Ultrabay
device such as an optical drive, a hard disk drive, and an extended
battery.
ThinkPad computers contain the following types of the internal CRUs:
Internal CRUs (located behind an access panel)
These CRUs are isolated parts within the computer that are concealed
by an access panel that is typically secured by either one or two
screws. Once the access panel is removed, only the specific CRU is
visible. Examples of these types of CRUs include a memory card and a
hard disk drive.
Internal CRUs (located within the product itself)
These CRUs are accessible only by opening the outer case of the
computer. Examples of these CRUs include the integrated keyboard
parts beneath the integrated keyboard and parts beneath the palm rest.
v A RoHS compliant FRU is identified by an R. An N in the RoHS ID column
means the part is not a RoHS compliant FRU.
v FRUs marked with 
OP are available as options.
