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 Ensure that all diskette fixes are installed prior to replacing any FRUs. And, 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. IBM ThinkPad 380XD, 385XD (2635) 3 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. 4 IBM ThinkPad 380XD, 385XD Safety Notices (Multi-lingual Translations) In this manual, safety notices appear in English with a page number reference to the appropriate multi-lingual, translated safety notice found in this section. The following safety notices are provided in English, French, German, Italian, and Spanish languages. Safety Notice 1 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 shorts. Avant de remettre l'ordinateur sous tension après remplacement d'une unité en clientèle, vérifiez que tous les ressorts, vis et autres pièces sont bien en place et bien fixées. Pour ce faire, secouez l'unité et assurez-vous qu'aucun bruit suspect ne se produit. Des pièces métalliques ou des copeaux de métal pourraient causer un court-circuit. Bevor nach einem FRU-Austausch der Computer wieder angeschlossen wird, muß sichergestellt werden, daß keine Schrauben, Federn oder andere Kleinteile fehlen oder im Gehäuse vergessen wurden. Der Computer muß geschüttelt und auf Klappergeräusche geprüft werden. Metallteile oder -splitter können Kurzschlüsse erzeugen. Prima di accendere l'elaboratore dopo che é stata effettuata la sostituzione di una FRU, accertarsi che tutte le viti, le molle e tutte le altri parti di piccole dimensioni siano nella corretta posizione e non siano sparse all'interno dell'elaboratore. Verificare ciò scuotendo l'elaboratore e prestando attenzione ad eventuali rumori; eventuali parti o pezzetti metallici possono provocare cortocircuiti pericolosi. Antes de encender el sistema despues de sustituir una FRU, compruebe que todos los tornillos, muelles y demás piezas pequeñas se encuentran en su sitio y no se encuentran sueltas dentro del sistema. Compruébelo agitando el sistema y escuchando los posibles ruidos que provocarían. Las piezas metálicas pueden causar cortocircuitos eléctricos.

IBM ThinkPad 380XD, 385XD (2635) 9 Safety Notice 6 To avoid shock, do not remove the plastic cover that surrounds the lower portion of the inverter card. 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. 10 IBM ThinkPad 380XD, 385XD 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. IBM ThinkPad 380XD, 385XD (2635) 11 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. 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. 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. 12 IBM ThinkPad 380XD, 385XD 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 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. IBM ThinkPad 380XD, 385XD (2635) 13 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. 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 14 IBM ThinkPad 380XD, 385XD 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. IBM ThinkPad 380XD, 385XD (2635) 15 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. 16 IBM ThinkPad 380XD, 385XD Laser Compliance Statement Some IBM Personal Computer models are equipped from the factory with a CD-ROM drive.

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 start-up sequence might have been altered. If you select an incorrect drive, data or programs can be overwritten. 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, unreproducible failure. Single failures can occur from a variety of reasons that have nothing to do with a hardware problem, 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. 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 38. Port Replicator Problems: If you suspect a problem with the Port Replicator, see "Port Replicator Checkout" on page 33. 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. IBM ThinkPad 380XD, 385XD (2635) 19 What to Do First: The service personnel must fill in the following information 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. Name and phone number of service personnel Date of service Date when the part failed Date of purchase Failure symptoms, error codes appearing on the monitor, and beep symptoms Procedure index and page number in which the failing FRU was detected Failing FRU name and the part number Machine type, model number, and serial number Customer's name and address Before checking problems with the computer, determine whether the damage is covered under the warranty by referring to the following: Warranty Note: During the warranty period, the customer may be responsible for repair costs if the computer damage was caused by misuse, accident, modification, unsuitable physical or operating environment, or improper maintenance by the customer.

Flash Memory Update: System setup programs and diagnostic tests are stored in the flash memory. A flash memory update is required when: A new version of the system program is installed. A new features or options is added to the computer. 28 IBM ThinkPad 380XD, 385XD To update the flash memory, do the following: 1. Obtain an appropriate diskette containing the update. 2. Insert the System Program Service diskette into drive A, and turn on the computer with ac power or a fully charged battery. 3. Select Update system programs from the menu. Power Systems Checkout To determine whether a power systems problem is due to the AC Adapter or the battery, do the following: 1. Remove the battery. 2. Connect the AC Adapter and check that power is supplied. 3. Disconnect the AC Adapter and install the charged battery; then check that power is supplied by the battery. If the problem is due to the AC Adapter, go to "AC Adapter Checkout" If the problem is due to the battery, go to "Battery Checkout" on page 30 If the problem is not due to the AC Adapter or the battery, go to "Backup Battery Checkout (Nonrechargeable)" on page 31 AC Adapter Checkout: This checkout is used only when the computer fails under ac power. If the problem occurs only when the AC Adapter is used with a port replicator, replace the replicator. If the power-on indicator does not turn on, check the power cord of the AC Adapter for conductivity and installation. 1. Unplug the AC Adapter cable from the computer and measure the output voltage at the cable plug. See the following figure: Pin 1 2 Voltage (V dc) +15.5 to +17.0 Ground a. If the voltage persists, go to the next step. b. If the voltage is correct, make sure the connection between the DC/DC card and the system board is not loose. IBM ThinkPad 380XD, 385XD (2635) 29 2. 3. 4. 5. c. Replace the DC/DC card. d. If the problem is not corrected, replace the system board. e. If the problem persists, go to "Undetermined Problems" on page 48. Unplug the AC Adapter cable from the ac power outlet and wait 5 minutes or longer to allow the overvoltage protection circuit to be fully discharged and initialized. Plug the AC Adapter cable into the ac power outlet. Measure the output voltage of the AC Adapter. If the voltage is still not correct, replace the AC Adapter. Note: An audible noise from the AC Adapter does not always indicate a defect. Battery Checkout: do the following: If the error is due to the battery, 1. Turn off the computer. 2. Remove the battery and measure the voltage between the battery terminals 1 (+) and 4 (-). Terminal 1 4 Voltage (V dc) / Signal +0 to +13.5 Ground (-) Note: Signal lines not used in these steps are used for communication between the system and the battery. 3. If the voltage is less than +11.0 V dc, the battery has been discharged. Recharge the battery. If the voltage is still less than +11.0 V dc after recharging, replace the battery. Note: The voltage of the battery could show 0 V because of the overdischarge protection circuit. Try to trickle charge the battery by attaching it to the computer with the AC adapter. 30 IBM ThinkPad 380XD, 385XD 4. If the voltage is more than +11.0 V dc, measure the resistance between the battery terminals 3 and 4. The resistance must be 4 to 30 K ohms. If the resistance is not correct, replace the battery. If the resistance is correct, replace the DC/DC card. Checking Operational Charging Note Battery charging will not start unless the Fuel-Gauge is below 95%. At below 95%, the battery will start charging to 100% of its capacity. This limitation protects the battery from overcharging and also prolongs its life. To check the operational charging, install a fully discharged battery or a battery that is less than 50% charged. Turn on the computer while it is connected to the AC Adapter. If the battery status indicator does not turn on, turn off the computer, remove the battery, and let the battery return to room temperature. Reinstall the battery, and turn on the computer (still connected to the AC Adapter). If the charge indicator still does not turn on, replace the battery. Backup Battery Checkout (Nonrechargeable) 1.

(Refer to "1010 DIMM Card and Backup Battery" on page 62 to remove the battery.) 4. Measure the voltage of the backup battery connector. Wire Red Black Voltage (V dc) +2.5 to +3.7 Ground IBM ThinkPad 380XD, 385XD (2635) 31 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. Status Indicator Checkout If an LED problem occurs, do the following: 1. Turn off the computer. 2. Turn on the computer. 3. All the LEDs in the indicator panel should turn on for a moment soon after the computer is powered on. Make sure they turn on. If the problem persists, replace the system board. System Board and CPU Card Checkout The system board and the CPU Card FRUs perform the operation on the computer. Processor problems can be caused by either FRU. Generally, the CPU Card has a lower failure rate. If a numeric code indicates the system board or the CPU Card as failing, do 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 "Undetermined Problems" on page 48. Note: Do not touch the keyboard and the pointing device when the system board is being tested. This might cause unexpected errors. 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 this procedure does not correct the problem, go to "Undetermined Problems" on page 48. TrackPoint III Checkout If the TrackPoint III does not work, do the following: 1. Run the ThinkPad Configration program and check if the configuration of the TrackPoint III is enabled. 2. If it is not, select Enable and enable it. 3. If you still have a problem, continue to the next step. 32 IBM ThinkPad 380XD, 385XD Drifting Pointer There may be cases when the pointer drifts for a short while on the screen, this is not a hardware problem.

The computer will not enter suspend mode when a communication link is active. The following events cause the computer to return from suspend mode to normal operation: The LCD is opened. The real time clock alarm is signaled. The ring indicator (RI) is signaled by a serial device or a PC Card device. The Fn key is pressed. An external keyboard key is pressed while the computer is operating with ac power. The computer exits suspend mode and enters hibernation mode when a preset timer condition is satisfied. Hibernation Mode: following occurs: In hibernation mode, the The system status, RAM, VRAM, and setup data are stored on the hard disk. The computer is powered off. Notes: The computer cannot enter hibernation mode if it is being powered by ac power and a communication PC Card is used. The following events cause the computer to enter hibernation 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 Configration program. The computer exits hibernation mode and resumes operation when the power-on switch is pressed. When power is turned on, the hibernation file in the boot record on the hard disk drive is read and system status is restored from the hard disk drive. 36 IBM ThinkPad 380XD, 385XD Port Replicator Power Overload: If a power shutdown occurs intermittently when PC Card devices are used with a port replicator, suspect an over-current problem. Some PC Card devices use much power, and if at some point the required power exceeds the allowed power, a power shutdown occurs. Isolate this problem to a device by removing each device simultaneously and then using the computer under the same condition as when the power shutdown occurred. This will determine which device is causing the overload. IBM ThinkPad 380XD, 385XD (2635) 37 Symptom-to-FRU Index The Symptom-to-FRU Index lists the symptoms and errors and the possible causes. The most likely cause is listed first. Note: Perform the FRU replacement or actions in the sequence shown in the "FRU/Action" columns. If a FRU replacement did not solve the problem, put the original part back in the computer. Do not replace a nondefective FRU. This index can also help you determine the next possible FRUs to be replaced when servicing a computer. Numeric error codes show the errors detected in POST or system operation. In the following error codes, X can be any number. If no codes are available, use narrative symptoms. If the symptom is not listed, go to "Undetermined Problems" on page 48. Note: For IBM devices not supported by diagnostic codes in the ThinkPad notebook computers, see the manual for that device.
