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 Toronto Vancouver Winnipeg 514-938-3022 905-316-4255 604-664-6464 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. © Copyright IBM Corp. 1999 1 Introduction Attention A customized setup configuration (other than default settings) may exist on the computer you are servicing. Running Automatic Configuration may alter those settings. Note the current configuration settings (using the View Configuration option) and verify that the settings are in place when service is complete. Hard Disk Drive Replacement Strategy: Always try to run a low-level format before replacing a hard disk drive. Attention The drive startup sequence in the computer you are servicing might have been changed. Be extremely careful during write operations such as copying, saving, or formatting. Data or programs can be overwritten if you select an incorrect drive. How to Use Error Messages: Use the error codes displayed on the screen to diagnose failures. If more than one error code is displayed, begin the diagnosis with the first error code. The cause of the first error code can result in false error codes being displayed. If no error code is displayed, see if the error symptom is listed in the Symptom-to-FRU Index for the computer you are servicing. How to Read POST Error Messages: POST error messages are displayed on the screen as three, four, five, or eight digits. The error messages that can be displayed as shorter POST messages are highlighted in this index. Some digits will represent different information for SCSI errors versus non-SCSI errors. The following example shows which digits display the shorter POST error messages and also defines the SCSI information in an eight-digit error message. Shorter POST Messages """"""""""""""""""""" " " " " " """"""""""""""""""""""""""""""""""""""""" " " " " " " " " " """"""""""""""""""""""""""""""""""""""""" " " " " " " " " Reserved " " " " " " Size (SCSI) """"""""""" " " Slot Number (SCSI) Device Code " Logical Unit 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. 2 Introduction Drive and Diskette Compatibility Matrix The following table provides identification information for 3.5-inch drives.

General Descriptions 7 Introduction Safety Notice 5 If the LCD breaks and the fluid from inside the LCD gets into your eyes or on your hands, immediately wash the affected areas with water for at least 15 minutes. Seek medical care if any symptoms from the fluid are present after washing. Si le panneau d'affichage à cristaux liquides se brise et que vous recevez dans les yeux ou sur les mains une partie du fluide, rincez-les abondamment pendant au moins quinze minutes. Consultez un médecin si des symptômes persistent après le lavage. Die Leuchtstoffröhre im LCD-Bildschirm enthält Quecksilber. Bei der Entsorgung die örtlichen Bestimmungen für Sondermüll beachten. Der LCD-Bildschirm besteht aus Glas und kann zerbrechen, wenn er unsachgemäß behandelt wird oder der Computer auf den Boden fällt. Wenn der Bildschirm beschädigt ist und die darin befindliche Flüssigkeit in Kontakt mit Haut und Augen gerät, sollten die betroffenen Stellen mindestens 15 Minuten mit Wasser abgespült und bei Beschwerden anschließend ein Arzt aufgesucht werden. Nel caso che caso l'LCD si dovesse rompere ed il liquido in esso contenuto entrasse in contatto con gli occhi o le mani, lavare immediatamente le parti interessate con acqua corrente per almeno 15 minuti; poi consultare un medico se i sintomi dovessero permanere. Si la LCD se rompe y el fluido de su interior entra en contacto con sus ojos o sus manos, lave inmediatamente las áreas afectadas con agua durante 15 minutos como mínimo.

Afin d'éviter tout risque de choc électrique, ne retirez pas le cache en plastique protégeant la partie inférieure de la carte d'alimentation. Aus Sicherheitsgründen die Kunststoffabdeckung, die den unteren Teil der Spannungswandlerplatine umgibt, nicht entfernen. Per evitare scosse elettriche, non rimuovere la copertura in plastica che avvolge la parte inferiore della scheda invertitore. Para evitar descargas, no quite la cubierta de plástico que rodea la parte baja de la tarjeta invertida. Safety Notice 7 Though main batteries have low voltage, a shorted or grounded battery can produce enough current to burn combustible materials or personnel. Bien que le voltage des batteries principales soit peu élevé, le court-circuit ou la mise à la masse d'une batterie peut produire suffisamment de courant pour brûler des matériaux combustibles ou causer des brûlures corporelles graves. Obwohl Hauptbatterien eine niedrige Spannung haben, können sie doch bei Kurzschluß oder Erdung genug Strom abgeben, um brennbare Materialien zu entzünden oder Verletzungen bei Personen hervorzurufen. Sebbene le batterie di alimentazione siano a basso voltaggio, una batteria in corto circuito o a massa può fornire corrente sufficiente da bruciare materiali combustibili o provocare ustioni ai tecnici di manutenzione. Aunque las baterías principales tienen un voltaje bajo, una batería cortocircuitada o con contacto a tierra puede producir la corriente suficiente como para quemar material combustible o provocar quemaduras en el personal. General Descriptions 9 Introduction Safety Notice 8 Before removing any FRU, power-off the computer, unplug all power cords from electrical outlets, remove the battery pack, then disconnect any interconnecting cables. Avant de retirer une unité remplaçable en clientèle, mettez le système hors tension, débranchez tous les cordons d'alimentation des socles de prise de courant, retirez la batterie et déconnectez tous les cordons d'interface. Die Stromzufuhr muß abgeschaltet, alle Stromkabel aus der Steckdose gezogen, der Akku entfernt und alle Verbindungskabel abgenommen sein, bevor eine FRU entfernt wird. Prima di rimuovere qualsiasi FRU, spegnere il sistema, scollegare dalle prese elettriche tutti i cavi di alimentazione, rimuovere la batteria e poi scollegare i cavi di interconnessione. Antes de quitar una FRU, apague el sistema, desenchufe todos los cables de las tomas de corriente eléctrica, quite la batería y, a continuación, desconecte cualquier cable de conexión entre dispositivos. Safety Information The following section contains the safety information that you need to be familiar with before servicing an IBM mobile computer. General Safety: general safety: Follow these rules to ensure 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. Do not attempt to lift any 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. 10 Introduction 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. 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. General Descriptions 11 Introduction If you need to work on a machine that has exposed 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 that power has been disconnected from a circuit. First, check that it has been 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 with the power on 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. 12 Introduction 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 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. General Descriptions 13 Introduction 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. Laser Compliance Statement Some IBM Personal Computer models are equipped from the factory with a CD-ROM drive. CD-ROM drives are also sold separately as options. The CD-ROM drive is a laser product.

Important Notes Only certified trained personnel should service the computer. Read the entire FRU removal and replacement page before replacing any FRU. Use new nylon-coated screws when you replace FRUs. Be extremely careful during such write operations 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 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 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 nondefective 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. 2. 3. 4. 5. 6. 7. 8. 9.

When the test detects an error, an error log is printed on the printer connected to the parallel port. See "Displaying the Error Log" on page 42 for more information. System Programs in Flash Memory: System setup programs and diagnostic tests are stored in the Flash memory. Flash Memory Update: The Flash memory update is required for the following conditions: New versions of system programs New features or options To update the Flash memory, do the following: 1. Get the appropriate diskette containing the update. 2. Insert the System Program Service Diskette into drive A and power on the computer. 3. Select Update system programs from the menu. Modem (DSP) Checkout Note: This section is for the built-in modem model. Do the following: 1. Go to the diagnostic menu by selecting Test in the Easy-Setup menu. 2. Select DSP and run the diagnostic tests. 3. If the test detects a DSP problem, replace the modem card. 34 Checkout Guide Port Replicator Checkout Use the following procedure to isolate a port replicator problem. The port replicator attaches to the system expansion connector at the rear of the computer: 1. Power off the computer. 2. Remove the failing devices from the port replicator. 3. Unplug the AC Adapter from the port replicator, if attached. 4. Remove the port replicator from the computer. 5. Reconnect the failing device directly to the computer. (If another device is already connected to the computer, remove it first.) 6. Go to the "Running the Diagnostics" on page 39 and run the diagnostics. 7. If the advanced diagnostic device test did not find an error, suspect a problem with the port replicator. 8. Power off the computer and reconnect the port replicator. 9. Power on the computer and run the following advanced diagnostic tests: Serial port test with the wrap plug installed on the port replicator Universal serial bus test with the USB parallel test cable Parallel port test with the wrap plug installed on the port replicator FDD-2 device test on the failing device with a scratch diskette 10. If diagnostic errors appear, replace the port replicator or the diskette drive. If the problem remains after the replacement, replace the system board. 11. If power problems appear only when the port replicator is used, replace the port replicator. Port Replicator Power Overload: If power shutdown occurs intermittently when PC Card devices are used through a port replicator with PC Card slots, suspect an over-current problem. Some PC Card devices use more power; if the maximum usage of each device occurs simultaneously, the total current will exceed the limit, thereby causing a power shutdown. Isolate this problem by removing one of the devices, use the computer under the same condition, and see whether a power shutdown occurs. Do this procedure for all devices to determine the cause. Power Systems Checkout To verify the symptom of the problem, power on the computer using each of the following power sources: 1. Remove the battery pack. 2. Connect the AC Adapter and check that power is supplied. General Descriptions 35 Checkout Guide 3. Disconnect the AC Adapter 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 checkout in the following list: "Checking "Checking "Checking "Checking the AC Adapter" Operational Charging" the Battery Pack" on page 37 the Backup Battery" on page 38 Checking the AC Adapter: You are here because the computer fails only when the AC Adapter is used: If the power problem occurs only when the port replicator is used, replace the port replicator. If the power-on indicator does not turn on, check the power cord of the AC Adapter for correct continuity and installation. If the operational charge does not work, go to Checking Operational Charging. 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 1 2 Voltage (V dc) +15.5 to +17.0 Ground If the voltage is not correct, replace the AC Adapter. If the voltage is within the range, do the following: Replace the system board. If the problem is not corrected, go to "Undetermined Problems" section of each model. Note: An audible noise from the AC Adapter does not always indicate a defect. Checking Operational Charging: To check operational charging, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. Perform operational charging. If the battery status indicator or icon does not turn on, remove the battery pack and let it return to room temperature. Reinstall the battery 36 Checkout Guide pack. If the charge indicator or icon still does not turn on, replace the battery pack. If the charge indicator still does not turn on, replace either the system board or DC-DC card that the battery is connected to. Then reinstall the battery pack. If the reinstalled battery pack is not charged, go to the next section. 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 can 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 1 (+) and 4 (-). See the following figure: Terminal 1 4 Voltage (V dc) + 0 to + 12.6 Ground (-) 3. If the voltage is less than +11.0 V dc, the battery pack has been discharged. Recharge the battery pack. Note: In this case, the battery pack is over-discharged. It takes at least 3 hours to recharge the battery pack even if the indicator does not turn on. If the voltage is still less than +11.0 V dc after recharging, replace the battery. 4. If the voltage is more than +11.0 V dc, measure the resistance between battery terminals 3 and 4. The resistance must be 4 to 30 K ohm. If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board. General Descriptions 37 Checkout Guide Checking the Backup Battery: Do the following: 1. Power off the computer and unplug the AC Adapter from the computer. 2. Turn the computer upside down. 3. Remove the backup battery (see "Removal and Replacement" section of each model). 4. Measure the voltage of the backup battery. See the following figure. Note: Be careful not to measure the wrong side of the backup battery. Wire Red Black Voltage (V dc) +2.5 to +3.2 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 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. If a numeric code indicates the system board or the CPU card as a failing FRU, or the CPU card is indicated 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. Note: Don't touch the keyboard and pointing device when the system board test is running. This might cause an unexpected error. 38 Running the Diagnostics 2. If FRU code 10 appears, replace the system board but do not replace the CPU card. Remove the CPU card from the old system board and install it 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 this procedure does not correct the problem, go to the "Undetermined Problems" section for each model. TrackPoint Checkout If the TrackPoint does not work, check the configuration in the ThinkPad Configuration program. If the configuration of the TrackPoint is disabled, select Enable to enable it. 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 in a short period of time. If a click button problem or the pointing stick problem occurs, do the following: 1. 2. 3. 4. 5. 6. Go to the Easy-Setup menu. Select an item with the pointing stick. Press any one of the click buttons. Verify that the item is selected. Move to another item with the pointing stick. Press the pointing stick (press-to-select), and verify that the item is selected. Note: This step is only for the model that has the press-to-select function. 7. 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 the problem. Do not replace a nondefective FRU. 1. Reseat the keyboard cables. 2. Replace the keyboard. 3. Reseat the card that the TrackPoint cable is directly connected to. 4. Replace the system board. Running the Diagnostics The following table lists the special tools needed for the diagnostics: General Descriptions 39 Running the Diagnostics Tool Name PC test card Tri-connector wrap plug USB parallel test cable Part Number 35G4703 72X8546 05K2580 Use either the TrackPoint or the cursor-moving keys to interact with the tests. The Enter key works the same as selecting the OK icon to reply OK. 1. Press and hold F1; then power on the computer. Hold F1 down until the Easy-Setup menu appears. 2. Click on Test. The basic diagnostic menu appears. 3. Click on a device to run the test. The test progress screen appears; then OK appears under the tested device icon when the test ends without any errors. 4. Start the Advanced Diagnostic test by pressing Ctrl+A on the basic diagnostic menu. The ThinkPad FRU connections window appears. 5. Click on Exit or press the Esc key. The keyboard test window appears. 6. When you press a key, a mark appears or disappears on the corresponding key position on the screen. Repeat this step for any keys that need to be tested. You can run the keyboard test if you press Ctrl+K in the advanced diagnostic test mode. 7. To exit the keyboard test, click on Exit or press Ctrl+Break. The advanced diagnostics window appears. 8. Click on a device to test it, or click on Test All to test all devices. Click on Looptest to run the tests in a repeated loop. The loop option menu appears. Click on a device; the mark appears beside the selected device. Repeat this step to select multiple devices. Click on OK to start the diagnostic loop. If no device is selected, all devices tests are looped. 9. To exit the loop, keep pressing Ctrl+Pause until the test exits. A beep sounds to notify that the exit interrupt is sensed by the test program. Press Esc to exit from the loop test. 40 Running the Diagnostics PC Card Slots Test The green LED on the PC test card turns on when the PC Card slot test is running. If the LED does not turn on, check that the card is installed correctly by reseating it. If the LED still does not turn on after the card 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. Universal Serial Bus (USB) Test At the advanced diagnostic window, do the following: 1. Connect the USB parallel test cable to the parallel connector of the computer. 2. Connect Connector 1 of the cable to the USB connector of the computer. Note: The illustration shows a ThinkPad 770 computer, but the procedure is the same for the other model. 3. Click on USB-1 to run the test. Follow the instructions on the screen. OK appears if the test passed, but three lines of error codes appear if the test failed. The defective FRU must be the system board. If you want to test the USB port on the port replicator, connect the USB parallel test cable to a port replicator and click on USB-2. If you want to test the USB ports on a docking station, connect the USB parallel test cable to the General Descriptions 41 Running the Diagnostics USB ports of the docking station and click on USB-3 and USB-4. Displaying the Error Log Diagnostic errors are printed on a printer attached to the parallel port when the error is detected. The error is also logged in the system memory. Use the following procedure to display the errors: 1. 2. 3. 4. Enter the advanced diagnostic test. Press Ctrl+E. The error log appears. To exit the screen, click on Exit or press Esc. The error log is not saved when system power is turned off. 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 menu, the device is defective. If necessary, adjust the contrast control to clearly distinguish the shades of the icon. Reseat the device connectors. If the symptom remains, replace the device or the system board. If a device that is not installed appears in a dark shade (for example, FDD-2 appears in a dark shade when no second FDD is installed), do the following: Note: Some ThinkPad 600E computers support only one FDD at a time. The icon of the diskette drive for such models is FDD instead of FDD-1 or FDD-2. 1. Replace the first device in the configuration, such as an FDD-1. 2. If the problem persists, replace the card that the device is connected to. The Parallel, and Serial icons are always displayed in a dark shade, because the icons represent subsystems of the system board and not the attachment of devices. The FDD-1 icon represents a device in the computer. 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 Diagnostic Error Codes If 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). 42 Running the Diagnostics The device ID and error code indicate the detailed portion of the FRU that caused the error. If replacing a FRU does not correct the problem, see the device ID or error code from the previous failure. If they have changed, the cause might be that the new FRU is defective or that the FRU was incorrectly installed. Device ID: If an error is detected by the diagnostic tests, a three-digit device ID is displayed, indicating the suspected device.
