FRU Replacement Strategy

Ensure that all diskette fixes are installed prior to replacingany FRUs. And, use the following strategy to preventunnecessary FRU replacement and service expense:

� If you are instructed to replace a FRU and thatdoes not correct the problem, reinstall the originalFRU before you continue .

� Some computers have both a processor board and asystem board. If you are instructed to replace eitherthe processor board or the system board, and the firstboard 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 oneFRU, an error code may be caused by any of theFRUs. Before replacing the adapter or device,remove the FRUs, one by one, to see if thesymptoms change. Replace only the FRU thatchanged the symptoms.

Attention

A customized setup configuration (other than defaultsettings) may exist on the computer you are servicing.Running Automatic Configuration may alter thosesettings. Note the current configuration settings (usingthe View Configuration option) and verify that thesettings are in place when service is complete.

The advanced diagnostic tests are intended to test onlyIBM products. Non-IBM products or modified options cangive false errors and invalid responses.

Hard Disk Drive Replacement Strategy:Always try to run a low-level format before replacing a harddisk drive.

Attention

The drive startup sequence in the computer you areservicing might have been changed. Be extremelycareful during write operations such as copying,saving, or formatting. Data or programs can beoverwritten if you select an incorrect drive.

How to Use Error MessagesUse the error codes displayed on the screen to diagnosefailures. If more than one error code is displayed, beginthe diagnosis with the first error code. The cause of thefirst error code can result in false error codes beingdisplayed. If no error code is displayed, see if the errorsymptom is listed in the Symptom-to-FRU Index for thecomputer you are servicing.

How to Read POST Error MessagesPOST error messages are displayed on the screen asthree, four, five, or eight digits. The error messages thatcan be displayed as shorter POST messages arehighlighted in this index. Some digits will representdifferent information for SCSI errors versus non-SCSIerrors.

The following example shows which digits display theshorter POST error messages and also defines the SCSIinformation in an eight-digit error message.

Introduction 9

Safety InformationThe following section contains the safety information thatyou need to be familiar with before servicing an IBMmobile computer.

General SafetyFollow these rules to ensure general safety:

� Observe good housekeeping in the area of themachines 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 themuscles in your back. Do not attempt to lift anyobjects that weigh more than 16 kg (35 lb) orobjects that you think are too heavy for you.

� Do not perform any action that causes hazards to thecustomer, or that makes the equipment unsafe.

� Before you start the machine, ensure that otherservice representatives and the customer's personnelare not in a hazardous position.

� Place removed covers and other parts in a safeplace, away from all personnel, while you areservicing the machine.

� Keep your tool case away from walk areas so thatother people will not trip over it.

� Do not wear loose clothing that can be trapped in themoving parts of a machine. Ensure that your sleevesare fastened or rolled up above your elbows. If yourhair is long, fasten it.

� Insert the ends of your necktie or scarf inside clothingor fasten it with a nonconductive clip, approximately 8centimeters (3 inches) from the end.

� Do not wear jewelry, chains, metal-frame eyeglasses,or metal fasteners for your clothing.

Attention: Metal objects are good electricalconductors.

� Wear safety glasses when you are: hammering,drilling soldering, cutting wire, attaching springs, usingsolvents, or working in any other conditions that mightbe hazardous to your eyes.

� After service, reinstall all safety shields, guards,labels, and ground wires. Replace any safety devicethat is worn or defective.

� Reinstall all covers correctly before returning themachine to the customer.


Electrical SafetyObserve the following rules when working on electricalequipment.

Important

Use only approved tools and test equipment. Somehand tools have handles covered with a soft materialthat does not insulate you when working with liveelectrical currents.

Many customers have, near their equipment, rubberfloor mats that contain small conductive fibers todecrease electrostatic discharges. Do not use thistype of mat to protect yourself from electrical shock.

� Find the room emergency power-off (EPO) switch,disconnecting switch, or electrical outlet. If anelectrical accident occurs, you can then operate theswitch or unplug the power cord quickly.

� Do not work alone under hazardous conditions ornear 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 thepower cord. If you cannot unplug it, ask the customerto power-off the wall box that supplies power to themachine and to lock the wall box in the off position.

� If you need to work on a machine that has exposedelectrical circuits, observe the following precautions:

– Ensure that another person, familiar with thepower-off controls, is near you.

Attention: Another person must be there toswitch off the power, if necessary.

– Use only one hand when working withpowered-on electrical equipment; keep the otherhand in your pocket or behind your back.

Attention: There must be a complete circuit tocause electrical shock. By observing the aboverule, you may prevent a current from passingthrough your body.

– When using testers, set the controls correctlyand use the approved probe leads andaccessories for that tester.

– Stand on suitable rubber mats (obtained locally,if necessary) to insulate you from grounds suchas metal floor strips and machine frames.

Observe the special safety precautions when youwork with very high voltages; these instructions are inthe safety sections of maintenance information. Useextreme care when measuring high voltages.

Introduction 11

� Regularly inspect and maintain your electrical handtools for safe operational condition.

� Do not use worn or broken tools and testers.� Never assume that power has been disconnected

from a circuit. First, check that it has beenpowered-off.

� Always look carefully for possible hazards in yourwork area. Examples of these hazards are moistfloors, nongrounded power extension cables, powersurges, and missing safety grounds.

� Do not touch live electrical circuits with the reflectivesurface of a plastic dental mirror. The surface isconductive; such touching can cause personal injuryand machine damage.

� Do not service the following parts with the power onwhen they are removed from their normal operatingplaces in a machine:

– Power supply units – Pumps

– Blowers and fans – Motor generators

and similar units. (This practice ensures correctgrounding 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 GuideThe intent of this inspection guide is to assist you inidentifying potentially unsafe conditions on these products.Each machine, as it was designed and built, had requiredsafety items installed to protect users and servicepersonnel from injury. This guide addresses only thoseitems. However, good judgment should be used to identifypotential safety hazards due to attachment of non-IBMfeatures or options not covered by this inspection guide.

If any unsafe conditions are present, you must determinehow serious the apparent hazard could be and whetheryou can continue without first correcting the problem.

Consider these conditions and the safety hazards theypresent:

� Electrical hazards, especially primary power (primaryvoltage on the frame can cause serious or fatalelectrical shock).

� Explosive hazards, such as a damaged CRT face orbulging capacitor

� Mechanical hazards, such as loose or missinghardware


The guide consists of a series of steps presented in achecklist. Begin the checks with the power off, and thepower cord disconnected.

Checklist:

1. Check exterior covers for damage (loose, broken, orsharp 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 groundcontinuity for 0.1 ohm or less between theexternal ground pin and frame ground.

b. The power cord should be the appropriate typeas 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-IBMalterations.

6. Check inside the unit for any obvious unsafeconditions, such as metal filings, contamination, wateror 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 13

Handling ElectrostaticDischarge-Sensitive DevicesAny computer part containing transistors or integratedcircuits (ICs) should be considered sensitive to electrostaticdischarge (ESD). ESD damage can occur when there is adifference in charge between objects. Protect against ESDdamage by equalizing the charge so that the machine, thepart, the work mat, and the person handling the part are allat the same charge.

Notes

1. Use product-specific ESD procedures when theyexceed the requirements noted here.

2. Make sure that the ESD protective devices youuse have been certified (ISO 9000) as fullyeffective.

When handling ESD-sensitive parts:

� Keep the parts in protective packages until they areinserted 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 whenyou are wearing a wrist strap.

� Use the black side of a grounded work mat to providea static-free work surface. The mat is especiallyuseful when handling ESD-sensitive devices.

� Select a grounding system, such as those listedbelow, to provide protection that meets the specificservice requirement.

Note

The use of a grounding system is desirable butnot 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 pointwhen working on a double-insulated orbattery-operated system. You can use coax orconnector-outside shells on these systems.

– Use the round ground-prong of the AC plug onAC-operated computers.

Grounding RequirementsElectrical grounding of the computer is required foroperator safety and correct system function. Propergrounding of the electrical outlet can be verified by acertified electrician.

Important Notes

� Only certified trained personnel shouldservice the computer .

� Read the entire FRU removal and replacementpage before replacing any FRU.

� Use new nylon-coated screws when youreplace FRUs .

� Be extremely careful during such writeoperations as copying, saving, or formatting.Drives in the computer that you are servicingmight have been rearranged, or the drive startupsequence might have been altered. If you selectan incorrect drive, data or programs might beoverwritten.

� Replace FRUs only for the correct model.When you replace a FRU, make sure the modelof the machine and FRU part number are correctby referring to the FRU parts list.

� A FRU should not be replaced because of asingle, unreproducible failure. Single failurescan occur from a variety of reasons that havenothing to do with a hardware defect, such as:cosmic radiation, electrostatic discharge, orsoftware errors. FRU replacement should beconsidered only when a recurring problem exists.If this is suspected, clear the error log and runthe test again. Do not replace any FRUs if logerrors do not reappear.

� Be careful not to replace a nondefective FRU.

ThinkPad 600 (2645) 19

Screw Tightening InformationLoose screws can cause a reliability problem. The IBMThinkPad computer addresses this problem withnylon-coated screws. Tighten screws as follows:

� Plastic to plastic

Turn an additional 90 degrees after the screw headtouches the surface of the plastic part:

� Logic card to plastic

Turn an additional 180 degrees after the screw headtouches the surface of the logic card:

� Torque driver

If you have a torque driver, refer to the “Torque”column in each step.

How to Use Error Messages: Use the errorcodes displayed on the screen to diagnose failures. Ifmore than one error code is displayed, begin the diagnosiswith the first error code. Whatever caused the first errorcode can result in false error codes being displayed. If noerror code is displayed, see if the error symptom is listedin the “Symptom-to-FRU Index” on page 38.

Port Replicator Problems: If you suspect aproblem with the port replicator, see “Port ReplicatorCheckout” on page 30.

How to Diagnose Multiple FRUs: When theadapter or device has more than one FRU, the error codecould be caused by any of them. Before replacing multipleFRUs, try removing or exchanging each FRU, one by onein the designated sequence, to see if the symptomschange.


What to Do First: The servicer must include thefollowing in the parts exchange form or parts return formthat is attached to the returned FRU:

1. Name and phone number of servicer2. Date of service3. Date that the machine failed4. Date of purchase5. Failure symptoms, error codes appearing on the

display, and beep symptoms6. Procedure index and page number in which the

failing FRU was detected7. Failing FRU name and part number8. Machine type, model number, and serial number9. Customer's name and address

Before checking problems with the computer, determinewhether the damage is covered under the warranty byreferring to the following.

ThinkPad 600 (2645) 21

Warranty Notes

During the warranty period, the customer may beresponsible for repair costs if the computer damagewas caused by misuse, accident, modification,unsuitable physical or operating environment, orimproper maintenance by the customer. The followinglist provides some common items that are not coveredunder warranty and some symptoms that may indicatethat the system was subjected to stress beyondnormal use.

The following is not covered under warranty:

� LCD panel cracked from the application ofexcessive force or from being dropped.

� Scratched (cosmetic) parts.� Cracked or broken plastic parts, broken latches,

broken pins, or broken connectors caused byexcessive force.

� Damage caused by liquid spilled into the system.� Damage caused by the improper insertion of a

PC Card or the installation of an incompatiblecard.

� Damage caused by foreign material in the FDD.� Diskette drive damage caused by the diskette

drive cover being pressed or by the insertion of adiskette with multiple labels.

� Damaged or bent diskette eject button.� Fuses blown by attachment of a nonsupported

device.� Forgotten computer password (making the

computer unusable).

The following symptoms might indicate damagecaused by nonwarranted activities:

� Missing parts might be a symptom ofunauthorized service or modification.

� HDD spindles can become noisy from beingsubjected to excessive force or from beingdropped.

� I9990303 errors can be caused by exposure tostrong magnetic fields.

How to Disable the Passwords: There are twopasswords used at a typical customer site: the power-onpassword and the supervisor password.

� The power-on password:1. Power off the computer.2. Remove the DIMM cover (see “1010 Backup

Battery” on page 65).3. Jumper the two password jumper pads (BIT-X)

on the system board:


4. Power on the computer and wait until the POSTends.

8. Power off the computer and reconnect the portreplicator.

9. Power on the computer and run the followingadvanced diagnostic tests:� Serial port test with the wrap plug (P/N 72X8546)

installed on the port replicator� Universal serial bus test with the test cable (P/N

05K2580) [see “Universal Serial Bus (USB) Test”on page 53]

� Parallel port test with the wrap plug (P/N72X8546) installed on the port replicator

� FDD-2 device test on the failing device with ascratch diskette

10. If diagnostic errors appear, replace the port replicatoror the diskette drive. If the problem remains after thereplacement, replace the system board.

11. If power problem appears only when the portreplicator is used, replace the port replicator.

If power shutdown occurs intermittently when using PCCard devices through a port replicator, suspect anover-current problem. Some PC Card devices use morepower; if the maximum usage of each devices occurssimultaneously, the total current will exceed the limit,thereby causing a power shutdown. Isolate this problemby removing one of the devices, and use the computerunder the same condition, and see whether a powershutdown occurs. Do this procedure for all devices todetermine the cause.

ThinkPad 600 (2645) 31

Port Replicator Power Overload: If a powershutdown occurs intermittently when PC Card devices areused with a port replicator, suspect an over-currentproblem. Some PC Card devices use much power; if themaximum usage of each device occurs simultaneously, thetotal current exceeds the limit, thereby causing a powershutdown. Isolate this problem by removing one of thedevices, and use the computer under the same conditionto see whether a power shutdown occurs. Do thisprocedure for all devices; then determine the cause.

Power Systems CheckoutTo verify the symptom of the problem, power on thecomputer using each of the following power sources:

1. Remove the battery pack and diskette drive.2. Connect the AC Adapter and check that power is

supplied.3. Disconnect the AC Adapter and install the charged

battery pack; then check that power is supplied by thebattery pack.

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

� “Checking the AC Adapter” on page 31� “Checking Operational Charging”� “Checking the Battery Pack”� “Checking the Backup Battery” on page 33

Checking the AC Adapter: You are herebecause the computer fails only when the AC Adapter isused:

� If the power problem occurs only when the portreplicator is used, replace the port replicator.

� If the power-on indicator does not turn on, check thepower cord of the AC Adapter for correct continuityand installation.

� If the operational charge does not work, go to“Checking Operational Charging.”

1. Unplug the AC Adapter cable from the computer andmeasure the output voltage at the plug of the ACAdapter cable. See the following figure:


(16 - 10 V)

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 is not corrected, go to

“Undetermined Problems” on page 50.� If the voltage is not correct, go to the next step.

Note: An audible noise from the AC Adapter does notalways indicate a defect.

Checking Operational Charging: To checkoperational charging, use a discharged battery pack or abattery pack that has less than 50% of the total powerremaining when installed in the computer.

Perform operational charging. If the battery statusindicator does not turn on, remove the battery pack and letit return to room temperature. Reinstall the battery pack.If the charge indicator still does not turn on, replace thebattery pack.

If the charge indicator still does not turn on, replace thesystem board. Then reinstall the battery pack. If thereinstalled battery pack is not charged, go to the nextsection.

Checking the Battery Pack: Battery charging willnot start until the Fuel-Gauge shows that less than 95% ofthe total power remains; with this condition the batterypack can charge to 100% of its capacity. This protects thebattery pack from being overcharged or having ashortened life.

Do the following:

1. Power off the computer.2. Remove the battery pack and measure the voltage

between battery terminals 1 (+) and 4 (−). See thefollowing figure:

Pin Voltage (V dc)

1 +14.5 to +17.0

2 Ground

ThinkPad 600 (2645) 33

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

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

If the voltage is still less than +11.0 V dc afterrecharging, replace the battery.

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

If the resistance is not correct, replace the batterypack. If the resistance is correct, replace the systemboard.

Checking the Backup Battery: Do the following:

1. Power off the computer and unplug the AC Adapterfrom the computer.

2. Turn the computer upside down.3. Remove the DIMM cover and backup battery (see

“1010 Backup Battery” on page 65).4. Measure the voltage of the backup battery. See the

following figure.

Note: Be careful not to measure the wrong side ofthe backup battery.

Wire Voltage (V dc)

Red +2.5 to +3.7

Black Ground


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

battery.� If the backup battery discharges quickly after

replacement, replace the system board.

System Board and CPU Card CheckoutThe processing functions are performed by both thesystem board and the CPU card. Processor problems canbe caused by either FRU. However, the CPU cardgenerally has a lower probability of failure. If a numericcode indicates the system board or the CPU card as afailing FRU, or the CPU card is indicated by a diagnostictest by showing FRU code 11, use the following procedureto isolate the problem:

1. Run the system board test to verify the symptom.This test verifies both the system board and the CPUcard. If no error is detected, return to “CheckoutGuide” on page 25.

Note: Don't touch the keyboard and pointing devicewhen the system board test is running. Thismay cause an unexpected error.

2. If FRU code 10 appears, replace the system boardbut do not replace the CPU card. Remove the CPUcard from the old system board and install it to thenew 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 this procedure does not correct the problem, go to“Undetermined Problems” on page 50.

TrackPoint CheckoutIf the TrackPoint does not work, check the configuration inthe ThinkPad Configuration program. If the configurationof the TrackPoint is disabled, select Enable to enable it.

If this does not correct the TrackPoint problem, continuewith the following. After you use the TrackPoint, thepointer drifts on the screen for a short time. Thisself-acting pointer movement can occur when a slight,steady pressure is applied to the TrackPoint pointer. Thissymptom is not a hardware problem. No service actionsare necessary if the pointer movement stops in a shortperiod of time.

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

1. Go to the Easy-Setup menu.2. Select an item with the pointing stick.3. Press any one of the three click buttons.4. Verify that the item is selected.5. Move to another item with the pointing stick.

ThinkPad 600 (2645) 35

6. Press the pointing stick (press-to-select).7. Verify that the item is selected.8. Verify that all 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 theproblem. Do not replace a nondefective FRU:

1. Reseat the keyboard cables.2. Replace the keyboard.3. Reseat the sub card.4. Replace the sub card.5. Replace the system board.

Power Management FeaturesThree power management modes are provided by thecomputer to reduce power consumption and prolongbattery power.

Standby Mode: In standby mode the followingoccurs:

� The LCD backlight turns off.� The hard disk drive motor stops.

Events that cause the computer to enter standby mode:

� Standby is requested by the Fn key (Fn+F3).� Screen blanking is enabled in the ThinkPad

Configuration program.

The computer exits standby and resumes operation whenany key is pressed.

Suspend Mode: In suspend mode, the followingoccurs, in addition to what occurs in standby mode:

� The LCD is powered off.� The hard disk drive is powered off.� The CPU stops.

Events that the computer to enter suspend mode:

� Suspend mode is requested by the Fn key (Fn+F4).� The LCD is closed.� The specified time has elapsed from the last

operation with the keyboard, the TrackPoint, the harddisk drive, the parallel connector, or the diskette drive;or the AC Adapter is plugged in. The time isspecified by Suspend Timer in the ThinkPadConfiguration program.

� The battery condition is low. The battery powerindicator blinks orange.

� Either the PS2 OFF or PS2 SUSpend command isset in the ThinkPad Configuration program.


Notes

1. In the ThinkPad Configuration program, thecomputer can be set to “Will not suspend even ifLCD is closed.”

2. If the computer is powered on with ac power andit is used with one of the communication PCCards, the computer enters standby mode; thePC Card and application program remain active.

3. The computer cannot enter suspend mode whilea communication link is connecting.

The following events cause the computer to resumeoperation from suspend mode:

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

or PC Card device.� The Fn key is pressed.� An external keyboard key is pressed while the

computer is operating with ac power.

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

Hibernation Mode

For the Windows NT User

A Windows NT user cannot create a hibernation file ina Windows NT system that uses the NTFS formatsystem, the Windows NT default format. If you wantto use hibernation mode, you should reinstall WindowsNT with a FAT format system.

Note: Before using hibernation mode, you need ahibernation file.

In hibernation mode, the following occurs:

� The system status, RAM, VRAM, and setup data arestored on the hard disk.

� The system is powered off.

Notes

1. In the ThinkPad Configuration program, thecomputer can be set to “suspend/hibernate whiledocked.”

2. The computer cannot enter hibernation modewhen:

� It is powered with ac power and acommunication PC Card is used.

� It is attached to a Dock I docking station.

ThinkPad 600 (2645) 37

Note

The computer cannot enter hibernation mode if it hasbeen powered on with ac power and a communicationPC Card is used.

The following events cause the computer to enterhibernation mode:

� Hibernation mode is requested by the Fn key(Fn+F12).

� Timer conditions are satisfied in suspend mode.� A critically low battery condition occurs.� The PS2 HIBernation command is set in the

ThinkPad Configuration program.

The computer exits hibernation mode and resumesoperation when the power-on switch is pressed. Whenpower is turned on, the hibernation file in the boot recordon the hard disk drive is read and system status isrestored from the hard disk drive.


Symptom-to-FRU IndexThe symptom-to-FRU index lists the symptoms and errorsand their possible causes. The most likely cause is listedfirst.

Note: Perform the FRU replacement or actions in thesequence shown in the “FRU/Action” columns. If aFRU replacement did not solve the problem, putthe original part back in the computer. Do notreplace a nondefective FRU.

This index can also help you determine the next possibleFRUs to be replaced when servicing a computer.

Numeric error codes show the errors detected in POST orsystem operation. In the following error codes, X can beany number.

If no codes are available, use narrative symptoms.

If the symptom is not listed, go to “UndeterminedProblems” on page 50.

Note: For IBM devices not supported by diagnosticcodes in the ThinkPad notebook computers,see the manual for that device.

Intermittent ProblemsIntermittent system hang problems can be caused by avariety of reasons that have nothing to do with a hardwaredefect, such as: cosmic radiation, electrostatic discharge,or software errors. FRU replacement should beconsidered only when a recurring problem exists.

When analyzing an intermittent problem, do the following:

1. Run the advanced diagnostic test for the systemboard 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 moreerrors exist.

Undetermined ProblemsYou are here because the diagnostic tests did not identifywhich adapter or device failed, installed devices areincorrect, a short circuit is suspected, or the system isinoperative. Follow these procedures to isolate the failingFRU (do not isolate nondefective FRUs).

Verify that all attached devices are supported by thecomputer.

ThinkPad 600 (2645) 51

Verify that the power supply being used at the time of thefailure is operating correctly. (See “Power SystemsCheckout” on page 31):

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 devicesb. Devices attached to the port replicatorc. Printer, mouse, and other external devices

d. Battery packe. Hard disk drivef. External diskette drive

g. DIMMh. CD-ROM and diskette drive in the UltraslimBay

i. PC Cards4. 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 nondefective FRU: a. System board b. LCD assembly c. CPU card

The error log is not saved when system power is turnedoff.

Checking the Installed Devices ListIf a device is installed but the icon appears in a gray shaderather than a dark shade on the basic diagnostics menu,the device is defective. Reseat the device connectors. Ifthe symptom remains, replace the device or the systemboard. If needed, adjust the contrast control to clearlydistinguish the shades of the icon.

If a device that is not installed appears in a dark shade (forexample, FDD-2 appears in a dark shade when no secondFDD is installed), do the following:

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

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

The Parallel, and Serial icons are always displayed in adark shade, because the icons represent subsystems ofthe system board and not the attachment of devices.

The FDD-1 icon represents a device in the UltraslimBay.The FDD-2 icon represents another device, such as:

� An external diskette drive attached to the computer� An external diskette drive attached to a port replicator� A diskette drive in a docking station

ThinkPad 600 (2645) 55

Diagnostic Error CodesIf an error is detected, the following appears:

� Large X on the left side of the device icon.� Device ID (three digits).� Error code (two digits).� FRU code (four digits).

The device ID and error code indicate the detailed portionof the FRU that caused the error. If replacing a FRU doesnot correct the problem, see the device ID or error codefrom the previous failure. If they have changed, the causemight be that the new FRU is defective or that the FRUwas incorrectly installed.

Device ID: If an error is detected by the diagnostictests, a three-digit device ID is displayed, indicating thesuspected device.
