FRU Replacement Strategy

Before Replacing Parts

Ensure that all diskette fixes are installed prior to replacing any FRUs listed in this manual.

Use the following strategy to prevent unnecessary FRU replacement and service expense:

 If you are instructed to replace a FRU and that

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 the first

board that you replaced does not correct the problem,

reinstall the original board, then replace the other

(processor or system) board.

 If an adapter or device consists of more than one

FRU, an error code may be caused by any of the

FRUs. 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

A customized setup configuration (other than default settings) may exist on the computer you are servicing. Running Automatic Configuration may alter those settings. Note the current configuration settings (using the View Configuration option) and verify that the settings are in place when service is complete.

6 IBM Mobile Systems HMM

The advanced diagnostic tests are intended to test

only

IBM products. Non-IBM products or modified options can give false errors and invalid responses.

Hard Disk Drive Replacement Strategy:

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 might have been changed. Be extremely careful during write operations such as copying, saving, or formatting. Data or programs can be overwritten if you select an incorrect drive.

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. The cause of the first error code can result in false error codes being displayed. 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.

How to Read POST Error Messages

POST error messages are displayed on the screen as three, four, five, or eight digits. The error messages that can be displayed as shorter POST messages are highlighted in this index. Some digits will represent different information for SCSI errors versus non-SCSI errors.

The following example shows which digits display the shorter POST error messages and also defines the SCSI information in an eight-digit error message.

Shorter POST Messages

┌────┬────┬────┬────┐

│ │ │ │ │ ┌────┬────┬────┬────┬────┬────┬────┬────┐ │ ð│ ð│ ð│ ð│ ð│ ð│ ð│ ð│ └────┴────┴────┴────┴────┴────┴────┴────┘

│ │ │ │ │ │ │ │

Reserved ││││││Size (SCSI)

└────┴────┘ │ │ Slot Number (SCSI)

ID (SCSI)

All SCSI devices are set to a different SCSI ID. Duplicate SCSI ID settings can generate a false error message. Use the SCSI ID to determine whether the error message is coming from an internal or an external device.

Safety Information

The following section contains 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:

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.

objects that weigh more than 16 kg (35 lb) or objects that you think are too heavy for you.

 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.

 Place removed covers and other parts in a safe

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

 Keep your tool case 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. Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is 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.

 Do 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, or 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.

Do not attempt to lift any

Introduction

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.

 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

 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

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: There must be a complete circuit to cause electrical shock. 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.

16 IBM Mobile Systems HMM

 Regularly inspect and maintain your electrical hand

tools for safe operational condition.

 Do not use worn or broken tools and testers. 

Never assume

from a circuit. First, 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.

 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

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.)

 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 intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM 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:

 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

bulging capacitor

 Mechanical hazards, such as loose or missing

hardware

Introduction

The guide consists of a series of steps presented in a checklist. 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 appropriate type

as specified in the parts listings.

c. Insulation must not be frayed or worn.

4. Remove the cover.

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

6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.

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

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

18 IBM Mobile Systems HMM

Handling Electrostatic Discharge-Sensitive Devices

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:

 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, to provide protection that meets the specific service requirement.

Note

The use of a grounding system is desirable but not required to protect against ESD damage.

– Attach the ESD ground clip to any frame ground,

ground braid, or green-wire ground.

– Use an ESD common ground or reference point

when working on a double-insulated or battery-operated system. You can use coax or connector-outside shells on these systems.

– Use the round ground-prong of the AC plug on

AC-operated computers.

Grounding Requirements

Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.

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

Important Notes

 Only certified trained personnel should

service the computer.

 Read FRU service procedures before replacing

any FRUs.

 Be extremely careful during write operations

such as copying, saving, or formatting.

Drives in the computer that you are servicing might have been rearranged or the drive startup sequence might have been altered. If you select an incorrect drive, data or programs can be written over.

 Replace FRUs only for the correct model.

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

 FRUs should not be replaced because of a

single, unreproducible failure. Single failures

can occur from a variety of reasons 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 recurring problem exists. If this is suspected, clear the error log and run the test again. Do not replace any FRUs if log errors do not reappear.

 Be careful not to replace a nondefective FRU.

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. The cause of the first error code can result in false error codes being displayed. If no error code is displayed, see if the error symptom is listed in the “Symptom-to-FRU Index” on page 40.

Port Replicator Problems: If you suspect a

problem with the Port Replicator, see “Port Replicator Checkout” on page 36.

How to Diagnose Multiple FRUs: When the

adapter or device has more than one FRU, the error code could be caused by either FRU. Before replacing multiple FRUs, try removing or exchanging each FRU, one by one in the designated sequence, to see if the symptoms change.

ThinkPad 380, 385 (2635)

What to Do First: The servicer must include the

following in the parts exchange form or parts return form that is attached to the returned FRU:

1. Name and phone number of servicer

2. Date of service

3. Date when part failed

4. Date of purchase

5. Failure symptoms, error codes appearing on display, and beep symptoms

6. Procedure index and page number in which failing FRU was detected

7. Failing FRU name and part number

8. Machine type, model number, and serial number

9. Customer's name and address

Before checking problems with the computer, determine whether the damage is covered under the warranty by referring to the following:

26 IBM Mobile Systems HMM

then the system board.

TrackPoint III Checkout

If the TrackPoint III does not work, check the configuration in the ThinkPad Features program. If the configuration of the TrackPoint III is disabled, select Enable to enable it.

If this does not correct the TrackPoint III problem, continue with the following:

The TrackPoint III does automatic compensations to adjust the pointer sensor. During this process, the pointer moves on the screen automatically for a short time. This self-acting pointer movement can occur when a slight, steady pressure is applied to the TrackPoint III pointer while the computer is powered on or while the system is running, or when readjustment is required because the temperature has exceeded its normal temperature range. This symptom does not indicate a hardware problem. No service actions are necessary if the pointer movement stops in a short period of time.

If a click button problem or pointing stick problem occurs, do the following:

1. Go to the Easy-Setup screen.

2. Select an item with the pointing stick.

3. Press either the left or right click button.

4. Verify that both buttons work correctly.

If either the pointing stick or the click button does not work, do the following actions one at a time to correct the problem. Do not replace a nondefective FRU.

 Reseat the keyboard flexible cables.  Replace the keyboard.  Replace the subcard.  Replace the system board.

Diskette Drive Test

Do the following to isolate the problem to a controller, drive, or diskette. A scratch, write enabled, nondefective 2HD diskette is required.

FDD-1 represents the built-in diskette drive. FDD-2 represents the external diskette drive attached through the port replicator.

ThinkPad 380, 385 (2635)

Checking the AC Adapter: You are here

because the computer fails only when the AC Adapter is used.

 If the power problem occurs only when the port

replicator is used, replace the replicator.

 If the power-on indicator does not turn on, check the

power cord of the AC Adapter for correct continuity and installation.

 If the operational charge does not work, go to

“Checking Operational Charging.”

1. Unplug the AC Adapter cable from the computer and measure the output voltage at the plug of the AC Adapter cable. See the following figure:

Pin Voltage (V dc)

 If the voltage is correct, do as follows:

– If the problem is not corrected, replace the

subcard.

– If the problem is not corrected, replace the

system board.

– If the problem is not corrected, go to

“Undetermined Problems” on page 51.

 If the voltage is not correct, go to the next step.

2. Unplug the AC Adapter cable from the ac power outlet and wait 5 minutes or longer to allow the overvoltage protection circuit to be fully discharged and initialized.

3. Plug the AC Adapter cable into the ac power outlet.

4. Measure the output voltage of the AC Adapter.

5. If the voltage is still not correct, replace the AC Adapter.

Note: An audible noise from the AC Adapter does not

always indicate a defective adapter.

Checking Operational Charging: To check

operational charging, 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 does not turn on, remove the battery pack and leave it to return to room temperature. Reinstall the

34 IBM Mobile Systems HMM

battery pack. If the charge indicator still does not turn on, replace the battery pack.

Checking the Battery Pack

1. Power off the computer.

2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 4 (−). See the following figure.

Terminal Voltage (V dc) / Signal 1 +0 to +13.5

2 N/C

3 Thermal 4 Ground (−)

5 Select 6 A-Ground

Note: Signal lines not used in these steps are used

for communication between the system and the battery.

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

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

Note: If the voltage of the battery pack is 0 V, it is

not defective.

4. If the voltage is more than +11.0 V dc, measure the resistance between battery terminals 3 and 4. The resistance must be 4 to 30 K ohm.

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

If the resistance is correct, replace the subcard.

7. If the advanced diagnostic device test does not find an error, suspect a problem with the port replicator of the system expansion bus.

8. Power off the computer and reconnect the port replicator.

9. Power on the computer and run the following advanced diagnostic tests:

 Serial port test with the wrap plug installed on

the replicator

 Parallel port test with the wrap plug installed on

the replicator

 FDD-2 device test on the failing device with

scratch diskette

10. If diagnostic errors appear, replace the replicator or diskette drive attachment unit. If the problem remains after the replacement, replace the system board.

11. If power problems appear only when the replicator is used, replace the replicator.

External Display Self-Test: If the display problem

occurs only when using an external display, use the following instruction to correct the problem.

Note: Before you replace a display, check that the 95XX

systems support either 63XX, 85XX, or 95XX displays to see if it is connected correctly.

If the screen is rolling, replace the external display. If that does not correct the problem, replace the FRUs in the following order until the problem goes away:

1. System board

2. Bus adapter (if used)

If the screen is not rolling, run the display self-test as follows:

1. Power-off the computer and display.

2. Disconnect the display signal cable.

3. Power-on the display

4. Set the contrast to its maximum position.

5. Set the brightness control to the center detent position.

Check for the following conditions:

 You should be able to vary the screen intensity by

adjusting the contrast and brightness control.

 The screen should be white or light gray, with a black

margin (test margin) on the screen.

 The screen is set to CRT or both by the ThinkPad

Features program.

ThinkPad 380, 385 (2635)

Note: The location of the test margin varies with the

type of display. The test margin might be on the top, bottom, or one or both sides.

If you do not see a test margin on the screen, replace the display. If there is a test margin on the screen, replace the system board.

Symptom-to-FRU Index

The Symptom-to-FRU Index lists the symptoms and errors and the possible causes. The most likely cause is listed first.

Note: Perform the FRU replacement or actions in the sequence shown in the “FRU/Action” columns. If a FRU did not solve the problem, put the original part back in the computer. Do not replace a nondefective FRU.

This index can also be used to help you decide which FRUs to have available when servicing a computer.

Numeric error codes show the errors detected in POST or system operation. In the following error codes, X can be any number.

If no codes are available, use narrative symptoms. If the symptom is not listed, go to “Undetermined

Problems” on page 51.

Note: For IBM devices not supported by diagnostic

codes in the ThinkPad notebook computers, see the manual for that device.

Diagnostic Error Codes

A detected error is shown as in the following example:

 Large X on the left side of the device icon.  Device ID (three digit)  Error code (two digit)  FRU code (four digit)

The device ID and error code are used to indicate the detail portion of the FRU that caused the error. If replacing a FRU does not correct the problem, see the device ID or error code from the previous failure. If they have changed, the cause might be because the new FRU is detective or that the FRU was incorrectly installed.

Device ID: If an error is detected by the diagnostic

tests, a three-digits device ID is displayed. The device ID indicates suspected device.

Intermittent Problems

Intermittent system hang problems can be caused by a variety of reasons 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 recurring problem exists.

When analyzing the intermittent problem, do the following:

1. Run the advanced 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.

50 IBM Mobile Systems HMM

Checking the Installed Devices List

If a device is installed but the icon appears in a gray shade rather than a dark shade on the basic diagnostics screen, the device is defective. Reseat the device connectors. If the symptom remains, replace the device or the system board. If needed, adjust the contrast control to clearly distinguish the shades of the icon.

If a device that is not installed appears in a dark shade (for example, FDD-2 appears in a dark shade when second FDD is installed), do the following:

1. Replace the first device in the configuration, such as an FDD-1.

2. If the problem remains, replace the system board.

The Parallel, and Serial icons are always displayed in a dark shade because the icons represent subsystems of the system board and not the attachment of the devices.

The FDD-1 and PCMCIA-1 icons represent the drive in the computer. The FDD-2 and PCMCIA-2 icons represent the devices in the port replicator or that is attached through the port replicator.

How to Run a Low-Level Format

1080 System Board Assembly

Notes:

1. The system unit serial number must be restored when the system board is replaced. To restore the system unit serial number, select the option “Set system identification” on the maintenance diskette. The flash ROM on the system board contains the vital product data (VPD)—that is, the system unit serial number, system board system number, and other computer-unique data.

2. Do not power off the computer when restoring the VPD. The system unit serial number label is attached to the base cover.

3. Before removing and replacing the system board assembly, make sure that the PCMCIA cards are removed and the eject levers are not sticking out.
