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.

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.

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.

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.

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 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.

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

Power System Checkout

To verify the symptom of the problem power on the computer using each of the following power sources:

1. Remove the battery ASM.

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

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 to the appropriate power supply check listed below:

 “Checking the AC Adapter”  “Checking the Operational Charging” on page 34  “Checking the Battery ASM” on page 34

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” on page 34.

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 +15.5 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 system board.  If the problem is not corrected, go to “Undetermined

Problems” on page 47

Note: An audible noise from the AC Adapter does not

always indicate a defective adapter.

ThinkPad 390E 33

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.

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 system 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 system board.

34 ThinkPad 390E

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.

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 and start PC Doctor. (See “PC Doctor System Diagnostics” on page 51 for details.)

2. Select Interactive Tests.

3. Select Mouse.

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 system board.

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

Hibernation Mode: For Windows NT or OS/2

users:

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.

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:

 Start the ThinkPad Configuration program.  Click on the Power Management icon.  Click on the Hibernation Options tab.

ThinkPad 390E

Do as

 Click on Enable Hibernation.  Click on OK.

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.

This index can also be used to help you decide the next possible FRUs to be replaced when servicing a computer.

Numeric error codes show the errors detected in POST or system operation (runtime). 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 47.

Note: For IBM devices not supported by diagnostic codes

in this ThinkPad computer, see the manual for that device.

ThinkPad 390E

Numeric Error Codes

The following is a list of the message that the BIOS can display. Most of them occur during POST. Some of them display information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the way it has been configured. Following the list are explanations of the messages and remedies for reported problems.

If the system fails after you make changes in the Setup menus, reset the computer, enter Setup and install Setup defaults or correct the error.

Note: If you cannot find a symptom or an error in this list

and the problem remains, see “Undetermined Problems” on page 47.

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 system board in loop mode at least 10 times.

2. If no error is detected, do not replace any FRUs.

46 ThinkPad 390E

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 33).

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. System board

b. LCD panel ASM

c. CPU card

CE Utility Program Diskette

Note: You can download the CE Utility Program Diskette

from the IBM website.

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

new LCD is not yet enabled (to function), connect an external CRT to see the program execution process.

Attention: Make sure the new ID code you choose corresponds to the LCD brand and type. If you write a wrong ID into the inverter, just reboot and re-execute the program and input the correct ID code.

4. Restart the computer — the new LCD should work normally.

Note: If the LCD cannot display after changing the ID

code, make sure you write the correct ID code or try reconnecting the LCD FPC cable connectors.

Setting the Thermal Sensor

The system is equipped with sensors to protect against system overheating. By setting the system and processor thermal thresholds, the system can turn on the cooling Fan ASM or shut down automatically when the temperature reaches the defined threshold parameters.

System experiencing frequent auto sensor shutdown may need to reset the thermal sensor threshold and execute the Fan ASM test to ensure the normal operation of the cooling Fan ASM (refer to “Fan ASM Checkout” on page 29).

Follow the steps below to set the thermal threshold:

1. Boot from the Utility Program Diskette.

2. Select Thermal Sensor Utility from PC DOS 7.0 Startup menu, then press F4.

Writing the RFID Data

The EEPROM on the system board contains the system unit serial number and the system board serial number. When you replace the system board, restore the system unit serial number using the RFID Utility in the ThinkPad CE Utility Diskette. The serial number label is attached to the computer.

This utility allows you to

 add S/N data to the EEPROM (option 1)  read S/N data from the EEPROM (option 2)  delete S/N data from the EEPROM (option 3)

Follow the instructions on the screen.

Flash UUID

The EEPROM on the system board contains the Universal Unique ID (UUID) — that is, for Microsoft or Internet use. When you replace the system board using the Flash UUID Utility in the ThinkPad CE Utility Diskette. The UUID utility will automatically assign the UUID via Windows.

FRU Removals and Replacements

This section contains information about removals and replacements.

 Do not damage any parts. Only certified and trained

personnel should service the computer.

 The arrows in this section show the direction of move-

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

 When 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.

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

shown in the procedures.

Safety Notice 1: Translation on page 4

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 6

60 ThinkPad 390E

LCD FRU Replacement Notice: The TFT LCD

for the notebook computer contains over 2,359,296 thinfilm 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:

 SVGA (12.1"): 5 or more bright dots, 5 or more dark

dots, or a total of 9 or more bright and dark dots

 XGA (13.3"/14.1"): 8 or more bright dots, 8 or more

dark dots, or a total of 9 or more bright and dark dots

Replacing the system Board: When you

replace the system board, restore the system unit serial number using the RFID Utility and reassign the UUID using the Flash UUID Utility in the ThinkPad 390E CE Utility Diskette. See “Writing the RFID Data” on page 49 and “Flash UUID” on page 49 respectively.

Note: Do not power off the computer while restoring the

RFID.

Screw Notices: When you service this machine, do

the following,

 Keep the screw kit (P/N 12J0808) in your tool bag.

 Always use new screws. Plastic-coated screws

cannot be reused.

 Use a torque screwdriver if possible.

Screw Tightening Information p.Loose screws

can cause a reliability problem. The IBM ThinkPad compute addresses this problem with plastic-coated screws. Tighten screws as follows,

Plastic to plastic Turn an additional

90 degrees after

the screw head touches the surface of the plastic part.

Logic card to plastic Turn an additional

180 degrees after

the screw head touches the surface of the logic card.
