Important Service Information

Important

Diskette fixes are customer installable. The diskette fixes are located on the PC Company Bulletin Board Service (BBS). The direct phone line for modem connection is 919-557-0001 or tieline 255-0001.

Advise customers to contact the PC Company HelpCenter at 800-772-2227 if they need assistance in obtaining or installing any diskette fixes.

Customers in Canada should call IBM HelpPC at 800-565-3344 for assistance or down-load information. The Canadian BBS phone numbers are:

Montreal 514-938-3022 Toronto 905-316-4255 Vancouver 604-664-6464 Winnipeg 204-934-2735

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.

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

Reserved Size (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.

exposed

16 IBM Mobile Systems HMM

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 HMM

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.

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 FRU service procedures before replacing

any 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 can be written over.

Replace FRUs only for the correct model.

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

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: cosmic radiation, electrostatic discharge, or software errors. FRU replacement should only be considered 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.

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” on page 40.

Port Replicator Problems: If you suspect a

problem with the Port Replicator, see “Port Replicator Checkout” in the “Common Devices Checkout” section.

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.

ThinkPad 365X, 365XD (2625)

What to Do First: The servicer must include the

following information on 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.

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.

Before checking problems with the computer, determine whether or not the damage is covered by the warranty by referring to the following:

28 IBM Mobile Systems HMM

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

Missing parts may be a symptom of unauthorized

service or modification.

HDD spindles can become noisy if subjected to

excessive force or if the HDD is dropped.

I9990303 errors can be caused by exposure to

strong magnetic fields.

How to Disable the Power-On Password:

1. Power off the computer.

2. Open the keyboard and lift the right-most section of the insulator sheet.

3. Push out the small door on the right side of the base cover. See page 100 for location.

4. Apply a short across the Power-On Password Jumper Pads.

Warning: When using a metal tool to short the two jumper pads, make sure the metal tool does not touch any metal parts other than the two jumper pads.

5. With the jumper tool in place, power on the computer to clear the password.

6. Remove the jumper and power off the computer.

7. Power on the computer and verify that the password has been cleared.

To reactivate the password, set the password again.

Supervisor and Hard Disk Passwords: The

Supervisor Password and the Hard Disk Password (HDP) are security features that are used to protect the system and the hard disk data from unauthorized access. No overriding capability is provided. If only a hard disk password is set, obtaining permission from the password owner to unlock the password is a prerequisite for running diagnostic tests and performing service. If both supervisor password and hard disk password are set, you can enter Easy-Setup by pressing the Enter key or power-on password at the supervisor password prompt. In this case, the Password, Start up, and Initialize icons cannot be selected.

System Board and CPU Card Checkout

The processing functions are performed by both the system board and the CPU card. Processor problems can be caused by either FRU. However, the CPU card generally has a lower probability of failure. When a numeric code calls the system board or the CPU card as a FRU, or the CPU card is called by a diagnostic test by showing FRU code 11, use the following procedure to isolate the problem:

1. Run the system board test to verify the symptom. This test verifies both the system board and the CPU card. If no error is detected, return to “Checkout Guide” on page 30.

2. If FRU code 10 appears, replace the system board but do not replace the CPU card. Transfer the CPU card from the old system board to the new system board.

3. If FRU code 11 appears, reseat the CPU card.

4. Rerun the test to verify the fix.

5. If FRU code 11 remains, replace the CPU card.

If above procedure does not correct the problem, go to “Undetermined Problems” on page 50.

Keyboard/Auxiliary Input Device Checkout

Remove the external keyboard if the internal keyboard is to be tested.

If the internal keyboard does not work or an unexpected character appears, make sure that the three flexible cables extending from the keyboard are correctly seated in the connectors on the keyboard card.

If the keyboard cable connections are correct, check the keyboard card.

32 IBM Mobile Systems HMM

TrackPoint III Checkout

If the TrackPoint III will not work, check the configuration in the ThinkPad Features program. If the configuration of the TrackPoint III is disabled, select Enable to enable it.

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

The TrackPoint III does automatic compensations 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 III pointer while the computer is powered on or while the system is running, or when 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 a click button problem or pointing stick problem occurs, do the following:

1. Go to the Easy-Setup screen.

2. Select an item with the pointing stick.

3. Press either the left or right click button.

4. Verify that both buttons work correctly.

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

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

Port Replicator Game Port Checkout

Do the following if a Port Replicator joystick problem occurs:

1. Connect the joystick to the Port Replicator game port.

2. Go to the Easy-Setup screen.

3. Select an item with the joystick.

4. Press any button of the joystick.

5. Verify that all buttons work correctly.

If either the joystick or a button does not work, replace the Port Replicator. If the problem still remains, replace the system board.

Diskette Drive Test

Do the following to isolate the problem to a controller, drive, or diskette. A scratch, write enabled, non-defective 2HD diskette is required.

FDD-1 represents the built-in diskette drive for 365X. FDD-2 represents a diskette drive in the Port Replicator or

ThinkPad 365X, 365XD (2625)

a diskette drive attached through the external diskette drive connector.

Warning: Make sure that the diskette does not have more than one label attached to it. Multiple labels can cause damage to the drive or can cause the drive to fail.

Do the following to select the test device:

1. Select the advanced diagnostics mode and select Tool; then select the FDD-1 or FDD-2 icon and press the spacebar. A mark appears next to the selected icon. Insert a blank diskette when instructed.

2. Run the diskette drive test.

3. If the controller test detects an error, FRU code 10 appears. Replace the system board.

4. If the controller test runs without errors, the drive read/write tests start automatically.

5. If the drive test detects an error, FRU code 50 for FDD-1 or 51 for FDD-2 appears. If the diskette itself is known to be good, replace the drive.

Status Indicators Checkout

If a status indicator LED problem occurs, do the following:

1. Power off the computer.

2. Power on the computer.

3. All the LEDs in the status indicator panel turn on for a moment soon after the computer is powered on. Verify that all indicators turn on correctly.

If some of the indicators do not turn on, replace the LED indicator card.

If the problem still remains, replace the keyboard card.

Power Systems Checkout

To verify the symptom of the problem, power on the computer using each of the power sources as follows:

1. Remove the battery pack, diskette drive, and hard disk drive.

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

3. Install the diskette drive or hard disk drive one at a time, and check that power is supplied from each power source.

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

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

“Checking the AC Adapter” on page 35. “Checking Operational Charging” on page 36. “Checking the Battery Pack” on page 36. “Checking the Backup Battery” on page 37.

34 IBM Mobile Systems HMM

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 a 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 36.

Note

There are two types of adapters. The procedure for checking both types is the same.

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 +14.5 to +17.0 2 Ground

If the voltage is correct, replace the system board. If the problem is not corrected, go to “Undetermined

Problems” on page 50.

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.

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.

ThinkPad 365X, 365XD (2625) 35

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 does not turn on, remove the battery pack and leave it to return to room temperature. Reinstall the battery pack. If the charge indicator still does not turn on, replace the battery pack.

Checking the Battery Pack: Battery charging will

not start until the Fuel-Gauge shows that less than 95% 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 overcharged or having a shortened life.

Do the following:

1. Power off the computer.

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

(-)

(T)

(+)

Terminal Voltage (V dc) / Signal

1 —

2 +8 to +13.5

3 — 4 —

5 Thermal 6 Ground (−)

Note

Signal lines, not used in these steps, are used for communication between the system and the battery.

36 IBM Mobile Systems HMM

3. If the voltage is less than +9.6 V dc, the battery pack has been discharged. Recharge the battery pack.

If the voltage is still less than +9.6 V dc after recharging, replace the battery.

Note

If the voltage of the battery pack is 0 V, it is not defective.

4. If the voltage is more than +9.6 V dc, measure the resistance between battery terminals 5 and 6. The resistance must be 4 K to 30 K ohm.

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

Checking the Backup Battery

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

2. Open the keyboard and remove the battery pack.

3. Lift the right-hand section of the black insulator sheet.

4. Locate the backup battery on the system board, shown at 1 .

5. Using a plastic tool, remove the backup battery from the system board.

DANGER

Do not use a metal tool when removing the backup battery. Use only a plastic tool.

ThinkPad 365X, 365XD (2625) 37

6. Measure the voltage of the backup battery. Refer to the following table for voltages:

Wire Voltage (V dc)

+ +2.5 to +3.7

− Ground

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

been discharged. Replace the backup battery.

If the backup battery discharges quickly after

replacement, replace the system board.

Note

If you cannot find a symptom or error in this list and the problem remains, see “Undetermined Problems” on page 50.

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 only be considered when a recurring problem exists.

When analyzing the intermittent problem, do the following:

ThinkPad 365X, 365XD (2625)

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.

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 the procedures below to isolate the failing FRU (do not isolate non-defective 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 34.)

1. Power off the computer.

2. Check the cables, wires, and connectors for short circuits and open circuits. 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 expansion bus

connector

c. Printer, mouse, and other external devices

d. Battery pack

e. Hard disk drive

f. Internal diskette drive or CD-ROM drive g. DIMM h. PC Cards

4. Power on the computer.

5. Determine if the problem has changed.

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

7. If the problem still remains, remove the backup battery and wait for 3 minutes; then replace the backup battery and set current date and time.

8. Determine if the problem has changed.

9. If the problem remains, replace the following FRUs one at a time. Do not replace a non-defective FRU. Keyboard card LCD assembly System board CPU card

Checking the Installed Devices List

If a device is installed but the icon appears in a gray shade rather than a dark shade on the basic diagnostics screen, the device is defective. Reseat the device connectors. If the symptom remains, replace the device or the system board. If needed, adjust the contrast control to clearly distinguish the shade of the icon.

If a device that is not installed appears in a dark shade (for example, FDD-2 appears in a dark shade when FDD is installed), do the following:

1. Replace the first device in the configuration, such as the FDD-1.

2. If the problem remains, replace the system board.

The PCMCIA, Parallel, and Serial icons are always displayed in a dark shade because the icons represent subsystems of the system board and not the actual attachment of the devices.

ThinkPad 365X, 365XD (2625)

second

The FDD-1 icon represents the first drive in the system configuration. Similarly, the FDD-2 icon represents the second drive, attached to the external diskette drive connector or through a Port Replicator.

Password Combinations (POP, HDP, PAP)

When the power-on password (POP), hard disk password (HDP), and supervisor password (PAP) are used, the following situations may occur:

When the POP is the same as the HDP

The POP prompt appears, but the HDP prompt does not appear.

When the POP is not the same as the HDP

The POP and HDP prompts both appear.

When the PAP and HDP are enabled

When a PAP is used, the HDP is enabled automatically, but no HDP prompt appears. The HDP is set to the same password as the PAP.

How to Run a Low-Level Format

Do the following to format the hard disk. Warning: Make sure the drive address to be formatted is correct. This procedure will erase all information on the disk.

1. Power off the computer.

2. Insert the ThinkPad 750Ce hardware maintenance diskette into diskette drive A and power on the computer.

Note

You can use this maintenance diskette for the ThinkPad 365X and 365XD computers.

3. Select Format the hard disk from the main menu.

4. Select the drive from the menu.

5. Follow the instructions on the screen.

PC Test Card LED

The green LED on the PC test card turns on when the PCMCIA test is running. If the LED does not turn on, check that the card is installed correctly by reseating the card. If it still does not turn on after it is reseated, try using another slot for the test. If the LED still does not turn on and the test fails, replace the FRU shown by the diagnostic error code.

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 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.

Safety Notice 8: Translation on page 14

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.
