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.

 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.
