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.

 Copyright IBM Corp. 1999

INTRODUCTION

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.

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

┌────┬────┬────┬────┐

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

│ │ │ │ │ │ │ │

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.

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.

Do not attempt to lift any

 Wear safety glasses when you are: hammering,

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.

exposed

INTRODUCTION

– 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.

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

Introduction

 Mechanical hazards, such as loose or missing

hardware

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.

INTRODUCTION

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.

To verify the symptom of a problem, do the following:

1. Power off the computer.

2. Remove the battery pack.

3. Connect the AC Adapter.

4. Check that power is supplied when you power on the computer.

5. Power off the computer.

6. Disconnect the AC Adapter and install the charged battery pack.

7. Check that power is supplied by the battery pack when you power on the computer.

If you suspect a power problem, see the appropriate power supply checkout in the following list:

 “Checking the AC Adapter”  “Checking operational charging” on page 38  “Checking the battery pack” on page 38  “Checking the backup battery” on page 39

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 port 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 38.

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:

(16 - 10 V)

Pin Voltage (V dc)

1 +15.5 to +17.0

Introduction 37

CHECKOUT GUIDE

Pin Voltage (V dc)

2 Ground

If the voltage is not correct, replace the AC Adapter. If the voltage is within the range, do the following:

 Replace the system board.  If the problem persists, go to “Undetermined

problems” on page 51.

Note

An audible noise from the AC Adapter does not always indicate a defect.

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 or 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.

If the charge indicator still does not turn on, replace the system board. Then reinstall the battery pack. If the reinstalled battery pack is not charged, go to the next section.

Checking the battery pack: Battery charging

does not start until the Fuel-Gauge shows that less than 95% of the total power remains; with this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or from having a shortened life.

Note

The battery pack might not be able to charged when it is hot. In that case, remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall it and recharge it.

Do the following:

1. Power off the computer.

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

38 ThinkPad 570 Hardware Maintenance Manual

CHECKOUT GUIDE

Terminal Voltage (V dc) 1 + 0 to + 12.6 4 Ground (−)

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

Note

In this case, the battery pack is over-discharged. It takes at least 3 hours to recharge the battery pack even if the indicator does not turn on.

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

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

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

Checking the backup battery: Do the following:

1. Power off the computer and unplug the AC Adapter from the computer.

2. Turn the computer upside down.

3. Remove the backup battery (see “1020 Backup battery” on page 56).

4. Measure the voltage of the backup battery. See the following figure.

Wire Voltage (V dc)

Red +2.5 to +3.2 Black Ground

 If the voltage is correct, replace the system board.  If the voltage is not correct, replace the backup

battery.

Introduction 39

 If the backup battery discharges quickly after

replacement, replace the system board.

SYMPTOM-TO-FRU INDEX

LCD-related symptoms

Important

The TFT LCD for the notebook computer contains over 2,359,000 thin-film transistors (TFTs). A small number of missing, discolored, or lighted dots (on all the time) 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 8 or

more.

Symptom / error FRU / action in sequence

No beep, power-on indicator on, and a blank LCD during POST.

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 an intermittent problem, do the following:

1. Run the 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.

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 these procedures to isolate the failing FRU (do not isolate nondefective FRUs).

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 systems checkout” on page 37):

1. Power off the computer.

2. Visually check them for damage. If any problems are found, replace the FRU.

3. Remove or disconnect all of the following devices: a. Non-IBM devices

b. Devices attached to the port replicator

c. Printer, mouse, and other external devices

FRU REMOVALS AND REPLACEMENTS

FRU removals and replacements

This section contains information about removals and replacements:

 Do not damage any part. Only certified and trained

personnel should service the computer.

 The arrows in this 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.

 If other FRUs must be removed before the failing

FRU is removed, 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” on page 89 for internal cable connections and arrangement information.

 When replacing a FRU, use the correct screw as

shown in the procedures.

Review “FRU replacement notices” on page 22 before replacing any FRU.

Safety Notice 1: Translation on page 6

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 8

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.

Safety Notice 8: Translation on page 12

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.
