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
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:
you are instructed to replace a FRU but the replacement does not correct the problem, reinstall the original FRU before you continue.
Some computers have both a processor board and a system board. If you are instructed to replace either the processor board or the system board, and replacing one
them does not correct the problem, reinstall that
board, and then replace the other one.
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
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.

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:
Observe good housekeeping in the area of the machines during and after maintenance.
When lifting any heavy object:
Ensure you can stand safely without slipping.
Distribute the weight of the object equally between
your feet.
Use a slow lifting force. Never move suddenly or
twist when you attempt to lift.
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
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
hazardous position.
Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine.
Keep your toolcase away from walk areas so that other people will not trip over it.
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
long, fasten it.
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.
not wear jewelry, chains, metal-frame eyeglasses, or
metal fasteners for your clothing.
Attention: Metal objects are good electrical
conductors.
Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching springs, using solvents,
working in any other conditions that might be
hazardous to your eyes.

After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective.
Reinstall all covers correctly before returning the machine to the customer.

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.
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.
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
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.
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.

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.
Regularly inspect and maintain your electrical hand tools for safe operational condition.
not use worn or broken tools and testers.
Never assume that power has been disconnected from
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.
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.
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
similar units. (This practice ensures correct
and grounding of the units.)
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.

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:
Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock)
Explosive hazards, such as a damaged CRT face or a bulging capacitor
Mechanical hazards, such as loose or missing hardware
determine whether there are any potentially unsafe
To 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:
Check exterior covers for damage (loose, broken, or sharp edges).
Power-off the computer. Disconnect the power cord.
Check the power cord for:
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.
The power cord should be the type specified in the parts list.
Insulation must not be frayed or worn.
Remove the cover.
4.
Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations.
Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water
other liquids, or signs of fire or smoke damage.
Check for worn, frayed, or pinched cables.
Check that the power-supply cover fasteners (screws
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
the same charge.
Notes
Use product-specific ESD procedures when they exceed the requirements noted here. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.
When handling ESD-sensitive parts:
Keep the parts in protective packages until they are inserted into the product.
Avoid contact with other people.
Wear a grounded wrist strap against your skin to eliminate static on your body.
Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap.
Use 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,
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
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.
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
incorrect drive, data or programs might be
overwritten.
Replace FRUs only for the correct model.
When you replace a FRU, make sure the model
the machine and the FRU part number are
correct by referring to the FRU parts list.
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.
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:

Power-on password:
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
booted.
Hard-disk password:
There are two hard-disk passwords (HDPs):
User HDPfor the user
Master HDPfor the system administrator, who can use
get access to the hard disk even if the user has
changed the user HDP
There are two modes for the HDP: User only and
Note:
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, 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:
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
replaced for a scheduled fee.
How to remove the power-on password
remove a POP that you have forgotten, do the
following:

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.
numeric error is displayed for each error detected in POST or system operation. In the displays, n can be any number.
numeric code is displayed, check the narrative descriptions of symptoms. If the symptom is not described there, go to “Intermittent problems on page 59.
Note
For an IBM device not supported by diagnostic codes in the ThinkPad notebook computers, see the manual for that device.

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
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:
XGA: 8 or more bright dots, 8 or more dark dots,
total of 9 or more bright and dark dots.
SXGA+: 11 or more bright dots, 13 or more dark
dots, or a total of 16 or more bright and dark dots.
Note:
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
beep, power-on indicator on, and a blank LCD during POST.

Intermittent problems

Intermittent system hang problems can be due to a variety
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:
Run the diagnostic test for the system board in loop mode at least 10 times.
error is detected, do not replace any FRUs.
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,
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 checkout on page 39.)
Power off the computer. Visually check each FRU for damage. Replace any damaged FRU. Remove or disconnect all of the following devices:
Non-IBM devices Devices attached to the port replicator Printer, mouse, and other external devices Battery pack Hard-disk drive
External diskette drive
DIMM CD-ROM and diskette drive in the Ultrabay
Cards

Power on the computer. Determine whether the problem has changed.
the problem does not recur, reconnect the removed
devices one at a time until you find the failing FRU.

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:
They maintain tight connections. They do not easily come loose, even with shock or vibration. They are harder to tighten. They should be used only once.
the following when you service this machine:
Do
Keep the screw kit (for the P/N, see “Miscellaneous parts on page 169) in your tool bag. Always use new screws. Use a torque screwdriver if you have one.
screws as follows:

Retaining serial numbers

This section includes the following descriptions:
Restoring the serial number of the system unit” “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.
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:
Install the ThinkPad hardware maintenance diskette version 1.69, and restart the computer.
From the main menu, select 1. Set System Identification.
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:
Install the ThinkPad hardware maintenance diskette version 1.69, and restart the computer.
From the main menu, select 1. Set System Identification.
Select 1. Add S/N data from EEPROM.
Follow the instructions on the screen.

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:
not try to service any computer unless you have
been trained and certified. An untrained person runs the risk of damaging parts.
Before replacing any FRU, review “FRU replacement notices on page 60.
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.
Follow the correct sequence in the steps for removing the FRU, as indicated in the drawings by the numbers
square callouts.
When turning a screw to replace a FRU, turn it in the direction indicated by the arrow in the drawing.
When removing the FRU, move it in the direction indicated by the arrow in the drawing.
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 127.
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).
