Use the following procedure as a guide for computer problems.

NOTE: The diagnostic tests are intended to test only IBM products. Non-IBM products, prototype cards, or modified options can give false errors and invalid system responses.

1. Obtain the failing symptoms in as much detail as possible.- Verify the symptoms by attempting to recreate the failure by  running the diagnostic test or by repeating the same operation.

   NOTE:  To run the diagnostics, refer to 'How to Run the Diagnostics'.

   • Use the following table with the verified symptom to determine  which page to go to. Search the symptoms column  and find the description  that best matches your symptom, then go to the page shown in the Go to column.

  How to Run the Diagnostics

Use either the TrackPoint III or the cursor move keys to interact with the tests. Pressing the Enter key works the same as selecting the OK icon to reply OK.

NOTE: The following tools are required:

• Wrap Plug (P/N 72X8546) for the serial and parallel connector tests.
• Wrap Plug (P/N 35G4680) for the PCMCIA tests.
• Scratch diskette for the FDD1 or FDD2 tests.
• Any data CD for the CD-ROM drive test.

1. Press and hold the F1 key, then power on the computer.  Hold the F1 key down until the Easy-Setup screen appears.- Select Test and press Enter.- Select a device and press Enter to run the test.- The test progress screen appears.- OK appears when the test ends without any errors.- Start the Advanced Diagnostic test as either of the following way:

         Pressing **Ctrl+A** on the basic diagnostic menu screen.
         Triple-click the icon on the right bottom corner on the basic diagnostic screen.
   
        - The ThinkPad FRU Connectors screen appears.
   
           This screen shows the state of the connection of all connectors.
   
           Check the connector if the **Not connected** message appears on the screen.- Click on **Exit** on the screen or press **Esc** to exit the screen.- The keyboard test screen appears.
   
               Check the keyboard.- Click on **Exit** on the screen or press **Ctrl+Pause** to exit the screen.- Select a device, and press **Enter** to start the tests.
   
                   The instruction appears, follow the instruction on the screen.- Select **Test All** to test all devices.- Select **Loop Test** to run the tests in a repeated loop.
   
                       A loop option menu appears in which a device loop or all-device
                       loop can be selected.
                       Select a device and press the **Spacebar** to select
                       a device. Repeat this step to select multiple devices.
                       Press Enter to start the diagnostic loop. If no device is selected,
                       all device tests are looped.
   
                      - 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.
   

  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 did not solve the problem, put the original part back in the computer. Do not replace a non-defective FRU.

This index can also be used to help you decide which FRUs to have available 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'.

NOTE: For any IBM device not supported by the diagnostic codes in this ThinkPad computer, see the manual for that device.

If an error is detected, the following appears:

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

 

The device ID and error code are used to indicate the detail portion of the FRU which 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 because the new FRU is defective or that the FRU was incorrectly installed.

If an error is detected by the diagnostic tests, a four-digit FRU code is displayed. The FRU code indicates two suspected FRUs. Replace the FRU that is indicated by the two leftmost digits first, then replace the FRU indicated by the two rightmost digits. No FRU is assigned to code 00. If only one FRU is suspected, the other FRU code is filled with zeros. Replace the FRU that is indicated by the two leftmost digits first, then replace the FRU that is indicated by the two rightmost digits. See the referenced page before replacing the FRU. The suspected FRU name is also displayed on the screen.

Intermittent Problems

Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a hardware defect, such as:

cosmic radiation, electrostatic discharge, or software errors.

FRU replacement should only be considered when a recurring problem exists.

When analyzing the intermittent problem, do the following:

1. Run the advanced diagnostic test for the system board in loop mode  at least 10 times.
2. If no error is detected, do not replace any FRUs.
3. If any error is detected, replace the FRU shown by the FRU code. Rerun the test to verify that no more errors exist.

In this EPRM, safety notices are referenced to the appropriate multi-lingual, translated safety notice 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 ci• 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.

 Safety Notice 2

Some standby batteries contain a small amount of nickel and cadmium. Do not disassemble it, recharge it, throw it into fire or water, or short-circuit it. Dispose of the battery as required by local ordinances or regulations. Use only the battery in the appropriate parts listing. Use of an incorrect battery can result in ignition or explosion of the battery.

Certaines batteries de secours contiennent du nickel et du cadmium. Ne les démontez pas, ne les rechargez pas, ne les exposez ni au feu ni à l'eau. Ne les mettez pas en court-circuit. Pour les mettre au rebut, conformez-vous à la réglementation en vigueur. Lorsque vous remplacez la pile de sauvegarde ou celle de l'horloge temps réel, veillez à n'utiliser que les modèles cités dans la liste de pièces détachées adéquate. Une batterie ou une pile inappropriée risque de prendre feu ou d'exploser.

Die Bereitschaftsbatterie, die sich unter dem Diskettenlaufwerk befindet, kann geringe Mengen Nickel und Cadmium enthalten. Sie darf nur durch die Verkaufsstelle oder den IBM Kundendienst ausgetauscht werden. Sie darf nicht zerlegt, wiederaufgeladen, kurzgeschlossen, oder Feuer oder Wasser ausgesetzt werden.

Power-off the computer.- Remove the failing devices from the replicator.- Unplug the AC adapter from the replicator, if attached.- Remove the port replicator from the computer.- Reconnect the failing device directly to the computer.  (If another device occupies the connector, remove it first.)- Go to General Checkout and follow that procedure.- If the advanced diagnostic device test does not find an error,  suspect a problem with the port replicator  or the system expansion bus.- Power-off the computer and reconnect the port replicator.- Power-on the computer and run the following advanced diagnostic tests:

              - Serial port test with the wrap plug installed on the replicator.- Parallel port test with the wrap plug installed on the replicator.- PCMCIA-2 test with the PC test card installed.- FDD-2 (FDD-1 if no drive is installed in the computer)
                       drive test on the failing device.
   
              - If diagnostic errors appear, replace the replicator or diskette
                 drive attachment unit.
   
                 If the problem remains after the replacement, replace the
                 system board.
   
                - If power problems appear only when using the replicator, replace the
                   replicator.
   

If power shut downs occur intermittently when using PCMCIA-2 devices via a port replicator, suspect an over-current problem. Some PCMCIA devices use more power; if the maximum usage of each device occurs simultaneously, the total current will exceed the limit, thereby causing a power shut down. Isolate this problem by removing one of the devices, and use the computer under the same condition, and see whether a power shut down occurs. Do this procedure for all devices then determine the cause.

Customer purchase of the larger AC adapter (50W, optional) is recommended, if it is not yet in use.

• If the TrackPoint II  does not work, check the configuration.  If the configuration of the TrackPoint II is set to Disabled or Off, change it to Enable or On.

If the problem remains, continue.

NOTE: TrackPoint II automatically compensates to adjust  the pointer sensor. This causes the pointer to move slightly on  the screen and then stop. Pointer  movement might occur when  a slight, steady pressure is applied to the TrackPoint II pointer when  the computer is powered-on or running, or  when exceeded temperature range requires re-adjustment.

• If the cursor floats or moves erratically, power-off and disconnect the  mouse. Power-on the computer. If the  problem goes away, replace the mouse. If the problem remains, replace the  keyboard.- For click button or pointing stick problems:

  1. Go to the Easy-Setup screen.
  2. Select an item with the pointing stick.
  3. Press either left or right click button.
  4. Verify that both buttons work correctly.

  If the pointing stick or the click button does not work,  do the following.

  1. Reseat the keyboard cables.
  2. Replace the keyboard.
  3. Replace the interposer card (355x, 360x, 750x, 755x).
  4. Replace keyboard control card (720).
  5. Replace the system board.

The TV Tuner Pack (hereafter called TV Tuner) is an option for watching TV programs or videos on the IBM TFT color notebook computer. The computer changes to TV reception when the removable diskette drive is replaced with the TV Tuner.

The TV screen and normal computer display are easily switched by using the Hot key on the front panel of the TV Tuner.

Undetermined Problems

You are here because the diagnostic tests did not identify which adapter or device failed, installed devices are incorrect, a short circuit is suspected, or the system is inoperative. Follow the procedures below to isolate the failing FRU (do not isolate non-defective FRUs).

Verify that all attached devices are supported by the computer.

Verify that the power supply being used at the time of the failure is operating correctly.

• For 2625 365X, XD see 'Power Systems Checkout' .
• For 2635
• 380 / 385 see 'Power Systems Checkout' .

1. Power off the computer.- Check the cables, wires, and connectors for  short circuits and open circuits. Visually check them for damage.  If any problems are found, replace the FRU.- Remove or disconnect all of the following devices.

   1. Non-IBM devices
   2. Devices attached to the expansion bus connector
   3. Printer, mouse, and other external devices
   4. Battery pack
   5. Hard disk drive
   6. Internal diskette drive or CD-ROM drive
   7. DIMM
   8. PC Cards
   • Power on the computer.
   • Determine if the problem has changed.
   • If the problem does not occur again, reconnect the removed devices  one at a time until you find the failing FRU.
   • If the problem still remains, remove the backup battery and wait for 3 minutes, then  replace the backup battery and set current date and time.
   • Determine if the problem has changed.
   • If the problem remains, replace the following FRUs one at a time.  Do not replace a non-defective FRU.

Checking the Installed Devices List

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

If a device that is not installed appears in a dark shade (for example, FDD-2 appears in a dark shade when NO second FDD is installed), do the following:

1. Replace the first device in the configuration, such as the FDD-1.
2. If the problem remains, replace the system board.

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

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

Do the following to format the hard disk.

  Make sure the drive address to be formatted is correct. This procedure will erase all information on the disk.

1. Power off the computer.

Screw Tightening Information

Loose screws can cause reliability problems. The IBM ThinkPad/WorkPad computer addresses this problem with nylon-coated screws.

Tighten screws as follows:

Plastic to Plastic

Turn an additional 90 degrees after the screw head touches the surface of the plastic part.

Logic Card to Plastic

Turn an additional 180 degrees after the screw head touches the surface of the plastic part.

Torque screw-drivers can be ordered from:

Read This First

Before you go to the checkout guide, be sure to read this section.

• Only certified, trained personnel  should service the computer .
• Read FRU service procedures before replacing any FRUs.
• Be extremely careful during write operations  such as copying, saving, or formatting. Drives in the computer that you are servicing  might have been rearranged or the drive startup  sequence might have been altered.  If you select an incorrect drive,  data or programs can be written over.
• Use only the correct FRUs. When you replace the FRU, make sure the model of the machine  and FRU part number are correct by referring to the parts list.
• FRUs should not be replaced because of a single, un-reproducible  failure. Single failures can occur from a variety of reasons  that have nothing to do with a hardware defect such as:  cosmic radiation, electrostatic discharge, or software errors.  FRU replacement should only be considered when  a recurring problem exists.  If this is suspected, clear the error log and run the test again.  Do not replace any FRUs if log errors do not reappear.
• Be careful not to replace a non-defective FRU.

How to 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.

If an error is detected by the diagnostic tests, a three-digit device ID is displayed. The device ID indicates the suspected device.

Abstract: 2635 ECA007 - LCD PIXEL POLICY CHANGE.

PURPOSE:

This ECA will be used on Warranty and Non-Warranty systems to replace TFT LCD panels with from 8 to 20 defective pixels.

FEATURES:
  Type,                  Machines Affected

PHYSICAL CHECK:

TFT LCD panels on systems in the FEATURE SECTION that contain from 8 to 20 defective pixels.

Defective Pixel definition:

Not firing (black), incorrect color firing, or incorrect color always on.

This ECA can not be applied to warranty or non-warranty systems if more then 20 pixels are defective.

Systems with this condition should have the LCD replaced using normal terms and conditions for warranty and non-warranty systems.

PREREQUISITES: NONE

COMPANION: NONE

CONCURRENT: NONE

DETAIL:

The IBM ThinkPad pixel policy pertaining to LCD replacement has changed.

The old policy required 21 or more defective pixels to replace the TFT LCD panel during warranty.

This policy has been revised to read 8 or more defective pixels.

Systems listed in the FEATURE SECTION that follow the PHYSICAL CHECK criteria should use this ECA to replace TFT LCD Panel FRUs that are exhibiting a pixel failure within the new Pixel Policy criteria.

Use the following TFT FRUs as replacements.

+-----------------------------------------+

+-----------------------------------------+

Defective pixels normally occur during the manufacturing process and are not a product of LCD use.

Therefore most conditions are present from the systems first power on.

NOTES: This ECA will expire on 8/31/99.

Order all FRU parts locally, and record Time and Material to service code 33, ECA 007, and OTHER OFFICE 990.

  Do not drop or apply any shock to the hard disk drive The hard disk drive is sensitive to physical shock. Incorrect handling can cause damage and permanent loss of data on the hard disk. Before removing the hard disk drive, have the user make a backup copy of all the information on the hard disk. Never remove the hard disk drive while the system is operating or is in suspend mode.
