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 - ThinkPad HMM Volume 3

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 - ThinkPad HMM Volume 3

 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 - ThinkPad HMM Volume 3

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.

Introduction 19

Read This First

This hardware maintenance manual contains information for the IBM ThinkPad 365 computer.

 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.

 Use only the correct FRUs. When you replace a

FRU, make sure the model of the machine and FRU part number are correct by referring to the parts listing.

 FRUs should not be replaced because of a single,

un-reproducible failure. Single failures can occur

from a variety of reasons that have nothing to do with a hardware defect such as electrostatic discharge or software errors. FRU replacement should only be considered when a recurring problem exists.

The servicer must include the following in the parts exchange form or part 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.

ThinkPad 365 (2625) 27

What to Do First

Before servicing the computer, determine whether or not the damage applies to the warranty by referring to the following:

Warranty Note

During the warranty period, the customer may be responsible for repair costs if the damage was caused by misuse, accident, modification, unsuitable physical or operating environment, or improper maintenance by the customer.

The following list provides some common items that are not covered under warranty and some symptoms that could indicate that the system was subjected to stresses beyond normal use.

Warranty Coverage Notes

The following is not covered under warranty:

 LCD panel cracked from being dropped or

applying too much force.

 Scratched (cosmetic) parts.  Cracked or broken plastic parts, broken latches,

broken pins or connectors caused by excessive force.

 Damage caused by liquid spilled onto the system.  Damage caused by improperly inserting a

PCMCIA card or installation of an incompatible card.

 Damage due to foreign material in the FDD or

FDD bay.

 Damage to the diskette drive caused by pressing

the diskette drive cover or inserting diskettes with multiple labels.

 Diskette eject button was bent or damaged.  Damage to the CD-ROM drive caused by

excessive force shocked or dropped.

 Fuse blown by attaching non-supported devices.  Computer or hard disk could not be used

because the password was forgotten.

If the following symptoms are present, they could indicate the damage was caused by non-warranted activity:

 Missing parts can be a symptom of unauthorized

service or modification.

 HDD spindles can become noisy if subjected to

excessive force or if dropped.

 Errors can be caused by exposure to strong

magnetic fields.

28 IBM Mobile Systems - ThinkPad HMM Volume 3

How to Use Error Messages: Use the error

codes or messages 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 41.

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.

Passwords: The Passwords are security features that

are used to protect the system and the hard disk data from unauthorized access. There are two types of passwords:

 User Password  Supervisor Password

How to Disable the Passwords

Important

This information is not available in this online HMM format. See your IBM Servicer or IBM Authorized Dealer for this procedure.

ThinkPad 365 (2625)

does not occur again, recheck the connector. If the problem remains, replace the device, and then the system board.

TrackPoint III Checkout

The TrackPoint automatically compensates 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 pointer while the computer is powered on or while the system is running, or re-adjustment 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 either the pointing stick or the click button will not work, do the following actions one at a time to correct the problem. Do not replace a non-defective FRU.

 Reseat the three keyboard cables.  Replace the keyboard.  Replace the keyboard card.  Replace the system board.

If the computer power problem remains, do the following:

2. Remove the battery pack, external diskette drive, and hard disk drive.

3. Connect the AC Adapter and check that power is supplied.

4. Connect one at a time, the external diskette drive, and hard disk drive and check that power is supplied from each power source.

5. Disconnect the AC Adapter, remove the hard disk and diskette drive, and install the charged battery pack; then check that power is supplied by battery pack.

ThinkPad 365 (2625)

6. Remove the memory card and PCMCIA cards and check the power supply. Reinstall one at a time and check the power supply.

7. Disconnect the AC Adapter. Remove the CD-ROM and Audio Card. Reinstall one at a time, connect the AC Adapter and check that power is supplied.

If you suspect a power problem, see the appropriate power supply check listed below.

 “Checking the AC Adapter.”  “Checking Operational Charging” on page 37.  “Checking the Battery Pack” on page 37.  “Port Replicator Power Overload” on page 40.

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” on page 37.

Use the following procedure to check the adapter.

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)

1 +10.0 to +16.0 2 Ground

 If the voltage is correct:

– Replace the DC/DC Card. – If the problem remains, replace the system

board.

 If the problem still is not corrected, go to

“Undetermined Problems” on page 49.

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

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

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

36 IBM Mobile Systems - ThinkPad HMM Volume 3

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 shows an amber battery status indicator when it is installed in the computer.

Perform operational charging. If the battery status indicator turns orange and the battery charging indicator turns green within two minutes, replace the AC Adapter.

Checking the Battery Pack: Battery charging will

not start until the Fuel-Gauge shows that less than 90% of the total power remains; with this condition the battery pack will charge to 100% of its capacity. This protects the battery pack from being over-charged or having a shortened life.

Before you perform the following procedure, be sure you have the correct battery pack for this model.

1. Power-off the computer.

2. Remove the battery pack and measure the voltage between battery terminals 2 (+) and 6 (−). See the following figure.

3. If the voltage is less than +7.2 V dc, the battery pack has been discharged or is defective. Recharge the battery. If the recharging does not work, go to Step 5 on page 38 to check the charging circuit.

If the voltage is still less than +7.2 V dc after the recharging, replace the battery.

4. If the voltage is more than +7.2 V dc, measure the resistance between battery terminals 4 and 6. The resistance must be 4K ohms to 30K ohms.

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

If the resistance is correct, replace the DC/DC card.

ThinkPad 365 (2625)

5. To check the charging circuit, do the following. Plug in the AC Adapter with the battery pack removed, then power-on the computer.

6. Measure the charging voltage between DC/DC terminals 2 (+) and 6 (−).

7. If the voltage is less then +9.0 V dc, replace the DC/DC card. If the voltage is more than +9.0 V dc, the charging circuit is working correctly, replace the battery pack.

Power Management Features

Five power management modes are provided by the computer to save power consumption and prolong battery power.

Standby Mode: When in standby mode the following

occurs:

 The LCD backlight turns off.  The hard disk motor stops.  The CPU clock is set to the lowest speed.

Events that cause entering of standby mode:

 Standby requested by the Fn key (Fn+F3).  No activity under auto-standby enabled by the

feature utility.

Events that cause exiting or resuming of standby mode:

 (Resume) Any key operation.  Ring wakeup if enabled.

Suspend Mode: When in suspend mode, the

following, in addition to the four actions of standby mode, occur:

 The Audio is powered-off  The CD-ROM is powered off.  The LCD power is powered-off.  The hard disk is powered-off.  The CPU is stopped.

When the computer is powered with AC power and is used with one of the following IBM PC cards, the computer does not enter suspend switch or power-management timeout; the PC card and application program remain active.

 IBM Modem In the following condition, the computer cannot enter the

suspend mode.

by either the LCD

 Active interrupts (CD-ROM activity, etc.)

Events that cause entering of suspend mode:

 Suspend mode is requested by the Fn key (Fn+F4).  The LCD is closed.  The specified time has elapsed from the last

operation with the keyboard, mouse, hard disk drive, parallel connector, diskette drive, or the AC Adapter is plugged in. The time is specified by in the setup program (if enabled).

 If the battery condition is low the system enters the

Safe Suspend mode and the configuration/setup information is saved. If the battery gets to critical the battery power indicator blinks (amber) and the system goes into the Hibernation mode.

Events that cause exiting or resuming of suspend mode:

 (Resume) The LCD is opened.  (Resume) Real time clock alarm signaled.  (Resume) Ring indicator (RI) signaled by serial or

PCMCIA device.

 (Resume) Any keyboard key is pressed.  (Exit) Timer conditions are satisfied to enter

hibernation mode.

Suspend Timer

Hibernation Mode: When in hibernation mode, the

following occurs:

 The system status, RAM, VRAM, and setup data are

stored on the hard disk.

 The system is powered-off.

 PCMCIA Data/FAX Modem  High Speed PCMCIA Data/FAX Modem  3270 Emulation Credit Card Adapter  5250 Emulation Credit Card Adapter  Token-Ring 16/4 Credit Card Adapter  Credit Card Adapter for Ethernet

by either the LCD

ThinkPad 365 (2625)

Events that cause entering of hibernation mode:

 The hibernation mode is requested by the Fn key

(Fn+F12).

 Timer conditions are satisfied in suspend mode.  Critical low battery condition. The system first goes

into safe suspend mode, then when the battery reaches critical the system goes into the hibernation mode.

Event that causes exiting of hibernation mode.

 The power-on switch is operated.

When power is turned on, the hibernation history of the boot record on the hard disk is recognized and system status is restored from the hard disk to resume operation.

Doze Mode: In the Doze mode, the system slows

down the central processing unit and the system uses less power. Enable the doze mode in the setup program. Exiting the doze mode is instantaneous by pressing any keyboard key.

Safe Suspend: Saves the computer state, then

enters the suspend mode.

Port Replicator Power Overload: If power shut

downs occur intermittently when using a port replicator, suspect an over-current problem. Some devices use more power; if the maximum usage of each device occurs simultaneously, the total current will exceed the limit, thereby causing a power shut down. Isolate this problem by removing one of the devices, and use the computer under the same condition to see whether a power shut down occurs. Do this procedure for all devices, then determine the cause.

Setup Utility

Note

The Setup Utility is ROM-resident and can only be started at a full-screen DOS prompt.

Do the following to run the Setup Utility.

1. Go to a DOS full screen.

2. Press Ctrl+Alt+F11.

3. Follow the instructions on the screen.

Note

When exiting the Setup Utility using Fn+6, press Ctrl+Alt together after returning to the full-screen

DOS. This ensure the keyboard controller is in the proper reset state.

When analyzing the intermittent problem, do the following:

1. Run the diagnostic test for the system board in loop mode at least 10 times.

2. If any error is detected, replace the FRU indicated. Rerun the test to verify that no more errors exist.

48 IBM Mobile Systems - ThinkPad HMM Volume 3

Undetermined Problems

You are here because the diagnostic tests did not identify which adapter or device failed, installed devices are incorrect, a short circuit is suspected, or the system is inoperative. Follow the procedures below to isolate the failing FRU (do not isolate non-defective FRUs).

Verify that all attached devices are supported by the computers.

Verify that the power supply being used at the time of the failure is operating correctly. (See “Power Systems Checkout” on page 35.)

1. Power-off the computer.

FRU Removals and Replacements

This section contains information about removals and replacements.

 The system board is sensitive to, and can be

damaged by, electrostatic discharge. Establish personal grounding by touching a ground point with one hand before touching these units.

An electrostatic discharge (ESD) strap must be used to establish personal grounding.

 Do not damage any parts. Only certified, trained

personnel should service the computer.

 The arrows in the “Removals and Replacements”

section show the direction of movement to remove a FRU, or to turn a screw to release the FRU. The arrows are marked in numeric order, in square callouts, to show the correct sequence of removal.

 When other FRUs must be removed before removing

the failing FRU, they are listed at the top of the page.

 To replace a FRU, reverse the removal procedure

and follow any notes that pertain to replacement. See “Locations” for internal cable connections and arrangement information.

 When replacing a FRU, use the correct screw size as

shown in the procedures.

Safety Notice 1: Translation on page 8

Before the computer is powered-on after FRU replacement, make sure all screws, springs, or other small parts, are in place and are not left loose inside the computer. Verify this by shaking the computer and listening for rattling sounds. Metallic parts or metal flakes can cause electrical short circuits.

Safety Notice 3: Translation on page 10

The battery pack contains small amounts of nickel. Do not disassemble it, throw it into fire or water, or short-circuit it. Dispose of the battery pack as required by local ordinances or regulations.
