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.

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

┌────┬────┬────┬────┐

│ │ │ │ │ ┌────┬────┬────┬────┬────┬────┬────┬────┐ │ 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.

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 conduc-

tors.

 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.

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 your-

self.

– 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 hard-

ware

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.

14 ThinkPad 390/i Series 1700

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 batteryoperated 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.

About This Manual

This manual contains service and reference information for the IBM ThinkPad 390/i Series 1700 products. Use this manual along with the advanced diagnostics tests to troubleshoot problems effectively.

The manual is divided into sections as follows:

 The introduction section provides general information,

guidelines, and safety information required to service computers.

 The product-specific section includes service, refer-

ence, and product-specific parts information.

This manual is intended for trained servicers who are familiar with ThinkPad products. Use this manual along with the advanced diagnostics tests to troubleshoot problems effectively.

Read This First

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

Important Notes

 Only certified trained personnel should service

the computer.

 Read the entire FRU service procedures before

replacing any FRUs.

 Use new nylon-coated screws when you replace

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 might be overwritten.

 Replace FRUs only for the correct model. When

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

 A FRU should not be replaced because of a

single, unreproducible failure. Single failures can

occur for 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

ThinkPad 390/i Series 1700

error log and run the test again. Do not replace any FRUs if log errors do not reappear.

Be careful not to replace a non-defective FRU.

28 ThinkPad 390/i Series 1700

3. Disconnect the AC Adapter and install the charged battery ASM; then check that power is supplied by the battery ASM.

If you suspect a power problem, refer the the appropriate power supply check listed below:

 “Checking the AC Adapter”  “Checking the Operational Charging”  “Checking the Battery ASM” on page 30

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 ThinkPad

Port Replicator with Advanced Etherjet Feature.

 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 the Operational Charging.”

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 +14.5 to +17.0 2 Ground

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

 Replace the DC-DC & BATT board.  Replace the planar board.  If the problem is not corrected, go to “Undetermined

Problems” on page 40

Note: An audible noise from the AC Adapter does not

always indicate a defective adapter.

Checking the Operational Charging: To

check operational charging, use a discharged battery pack (Battery ASM) or a Battery ASM that has less than 50% of the total power remaining when installed in the computer.

ThinkPad 390/i Series 1700 29

Perform operational charging. If the battery status indicator does not turn on, remove the Battery ASM and let it return to room temperature. Reinstall the Battery ASM.

If the charge indicator still does not turn on, replace the Battery ASM. If the charge indicator still does not turn on, replace the DC-DC & BATT board, then the planar board. Then reinstall the Battery ASM. If the reinstalled Battery ASM is not charged, go to the next section.

Checking the Battery ASM: Battery ASM

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

Do the following:

1. Power off the computer.

2. Remove the Battery ASM and measure the voltage between battery terminals 1(+) and 7(-). See the following figure:

Note: Signal lines, not used in these steps, are used

for communications between the system and the battery.

3. If the voltage is less than 10.6V (Li-Ion) or 9.6V (NiMH), the Battery ASM has been discharged, recharge the Battery ASM. If the voltage is still less than 10.6V (Li-Ion) or 9.6V (NiMH), replace the battery.

4. If the voltage is more than 10.6V (Li-Ion) or 9.6V (NiMH), measure the resistance between battery terminals 5 and 7. The resistance must be 390 ohm (Li-Ion) or 4 to 3K ohm. If the resistance is not correct, replace the Battery ASM. If the resistance is correct, replace the DC-DC & BATT board then the planar board.

TrackPoint Checkout

If the external mouse is connected, the TrackPoint does not work. In this case, please detach the external mouse to check the TrackPoint.

30 ThinkPad 390/i Series 1700

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

After you use the TrackPoint, the pointer drifts on the screen for a short time. This self-acting pointer movement can occur when a slight, steady pressure is applied to the TrackPoint pointer. This symptom is not a hardware problem. No service actions are necessary if the pointer movement stops ina short period of time.

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

1. Boot from the diagnostics diskette and start the PQA program (please refer to “PQA System Diagnostics” on page 42).

2. Go to Pointing Dev. in the test items.

3. Press F2 in the test items.

4. Follow the instructions in the message window.

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

1. Reseat the keyboard cables.

2. Replace the keyboard.

3. Replace the planar board.

2. In the IBM BIOS Setup Utility, the computer can be set to suspend when docked.

The following events cause the computer to resume operation from suspend mode:

 The Lid is opened.  The real time clock alarm is signaled.  The ring indicator (RI) is signaled by a serial device

or a PC Card device.

 The Fn key is pressed.  Wake on LAN occurs.  Power switch is pressed.

The computer also exits suspend mode when timer conditions are satisfied for entering hibernation mode.

Hibernation Mode: For Windows NT or OS/2

user:

A Windows NT or OS/2 user cannot create a hibernation file in a Windows NT or OS/2 system that uses the NTFS/HPFS format system. If you want to use hibernation mode, you should reinstall Windows NT with a FAT format system. Also, if boot manager is installed, the computer cannot enter hibernation mode.

Note: Before using hibernation mode, you need a

hibernation file.

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.

32 ThinkPad 390/i Series 1700

Notes:

1. In the ThinkPad Configuration program, the computer can be set to suspend when docked.

2. The computer cannot enter hibernation mode when it is attached to the ThinkPad Port Replicator with Advanced Etherjet Feature.

Events that cause the computer to enter hibernation mode:

 Hibernation mode requested by function key

(Fn+F12).

 Timer conditions are satisfied in suspend mode when

hibernate by timer is enabled.

 A critically low battery condition occurs.  The power switch is pressed. (BIOS Setup)

The compute exits hibernation mode and resumes operation when the power-on switch is pressed. When power is turned on, the hibernation file in the boot record on the hard disk drive is read and the system status is restored from the hard disk drive.

The following events cause the computer to resume operation from hibernation mode.

 The power switch is pressed.  The real time clock alarm is signaled.  Wake on LAN occurs.

How to Create the Hibernation Function:

follows:

 Turn off the computer.  Insert the hibernation utility diskette into the diskette

drive (you can create the diskette using the Diskette Factory).

 Turn on the computer.  Follow the instructions on the screen.

Note: If you change the memory size, you need to

recreate the hibernation file or partition. For partition-based hibernation, use the hibernation utility to delete the partition first before creating a new one.

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 replacement does not solve the problem, put the original part back in the computer. Do not replace a non-defective FRU.

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, electronic 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 advanced diagnostic test for the planar 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, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate nondefective FRUs).

Verify that the power supply being used at the time of the failure is operating correctly. (See “Power System Checkout” on page 28).

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 ThinkPad Port

Replicator with Advanced Etherjet Feature

c. Printer, mouse, and other external devices

d. Battery ASM

e. Hard disk drive

f. DIMM

g. CD-ROM and Diskette Drive (FDD ASM) in the

Combobay (UltraBay FX)

h. PC Cards (PCMCIA)

4. Power on the computer.

5. Determine if the problem has changed.

6. If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU.

7. If the problem remains, replace the following FRUs one at a time. Do not replace a non-defective FRU.

a. Planar board

b. LCD panel ASM

c. CPU card

40 ThinkPad 390/i Series 1700

CE Utility Program Diskette Setting the LCD Panel ID

There is an EEPROM in the inverter which stores its supported LCD type ID code. If you replace a LCD with one of a different brand or use a new inverter, the ID information in the inverter EEPROM should be updated.

Follow the steps below to set the LCD Panel ID:

1. Boot from the Utility Program Diskette.

2. Select LCD Panel ID Utility from PC DOS 7.0 Startup Menu.

3. Follow the instructions on the screen to read the current or to set a new LCD Panel ID code.

Note: When you set a new LCD Panel ID and the
