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.

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

the Symptom-to-FRU Index for the computer you are

servicing.

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.

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.

v If

Safety information

After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective.

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

Fan Louvers on the machine help to prevent overheating of internal components. Do not obstruct fan louvers or cover them with labels or stickers.

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

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.

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

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:

–

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.

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 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-IBM features or options not covered by this inspection guide.

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.

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.

Introduction

–

Safety information

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.

Exception: If only an SVP is installed, the password

prompt does not appear when the operating system is booted.

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

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.

Power off the computer. Remove the battery pack. Connect the ac adapter. Check that power is supplied when you power on the computer. Power off the computer. Disconnect the ac adapter and install the charged battery pack. Check that the battery pack supplies power when you power on the computer.

If you suspect a power problem, see the appropriate one

the following power supply checkouts:

“Checking the ac adapter” “Checking operational charging” on page 43 “Checking the battery pack” on page 43 “Checking the backup battery” on page 44

Checking the ac adapter

You are here because the computer fails only when the ac adapter is used:

the power problem occurs only when the port

replicator is used, replace the port replicator.

the power-on indicator does not turn on, check the power cord of the ac adapter for correct continuity and installation.

the computer does not charge during operation, go to ″Checking operational charging.″

check the ac adapter, do the following:

Unplug the ac adapter cable from the computer. Measure the output voltage at the plug of the ac adapter cable. See the following figure:

Pin Voltage (V dc)

+15.5 to +17.0

Checking operational charging

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

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.

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%

its capacity. This protects the battery pack from being

overcharged or from having a shortened life.

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

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

reinstall and recharge it.

check the battery pack, do the following:

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

Terminal Voltage (V dc)

16.8

Ground (−)

5(-)

1(+)

the voltage is less than +14.4 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 +14.4 V dc after recharging, replace the battery.

the voltage is more than +14.4 V dc, measure the resistance between battery terminals 4 and 5. The resistance must be 4 to 30 K .

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

Checking the backup battery

the following: Power off the computer, and unplug the ac adapter from it. Turn the computer upside down. Remove the battery pack (see “1010 Battery pack” on page 73). Remove the backup battery (see “Checking the battery pack” on page 43). Measure the voltage of the backup battery. See the following figure.

Important

The TFT LCD for the notebook computer contains many thin-film transistors (TFTs). The presence of a small number of dots that are missing, discolored, or always lighted is characteristic of TFT LCD technology, but excessive pixel problems can cause viewing concerns. 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.

Note:

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

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

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 42.)

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

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 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:

Keep the screw kit (for the P/N, see “Miscellaneous parts” on page 133) in your tool bag. Always use new screws. Use a torque screwdriver if you have one.

screws as follows:

FRU replacement notices

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:

“Restoring the serial number of the system unit” “Retaining the UUID” on page 71

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

Write down that number.

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

the label attached on the bottom of the computer.

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.

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:

Install the ThinkPad Hardware Maintenance Diskette Version 1.69, and restart the computer.

From the main menu, select 4. Assign UUID.

new UUID is created and written. If a valid UUID

already exists, it is not overwritten.

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 69.

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 108.

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: 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 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).
