Fn Key Combinations

The following table shows the Fn key and function key combinations and their corresponding functions.

The Fn key works independently from the operating system.

The operating system obtains the status through the system management interface to control the system.

Each time you press the Function key  
one of the following messages (called On-Screen Message) appears at the top left corner of the LCD.

The changed values are automatically saved when you return to the TV Channel On-Screen message. The values are not saved when you power-off the TV Tuner without returning to this message.

The ThinkPad 380 and 385 series encompass dependable, all-in-one notebooks that incorporate internal CD-ROM drives.

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.

2. 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 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'.

What to Do First

The servicer must include the following information on the parts exchange form or parts return form that is attached to the returned FRU:

1. Name and phone number of servicer.
2. Date of service.
3. Date when part failed.
4. Date of purchase.
5. Failure symptoms, error codes appearing on display,  and beep symptoms.
6. Procedure index and page number in which failing FRU was detected.
7. Failing FRU name and part number.
8. Machine type, model number, and serial number.
9. Customer's name and address.

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

Note for Warranty 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. The following list provides some common items that are not covered under warranty and some symptoms that may indicate the system was subjected to stresses beyond normal use.

  The following is not covered under warranty:

• LCD panel cracked by applying excessive force or by being dropped.
• Scratched (cosmetic) parts.
• Cracked or broken plastic parts, broken  latches, broken pins,  or broken connectors caused by excessive force.
• Damage caused by liquid spilled into the system.
• Damage caused by improperly inserting a PCMCIA card or installation  of an incompatible card.
• Damage caused by foreign material in the diskette drive slot.
• Diskette drive damage caused by pressing the  diskette drive cover or inserting diskettes with multiple labels.
• Damaged or bent diskette eject button.
• CD-ROM drive damage caused by excessive force, shock, or from  being dropped.
• Fuses blown by attaching a non-supported device.
• Forgotten computer or hard disk password  (making computer or hard disk unusable).

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

• Missing parts may be a symptom of unauthorized service or  modification.
• HDD spindles can become noisy if subjected to  excessive force or if the HDD is dropped.
• I9990303 errors  can be caused by exposure to strong magnetic fields.

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

How to Diagnose Multiple FRUs

When the adapter or device has more than one FRU, the error code could be caused by either FRU. Before replacing multiple FRUs, try removing or exchanging each FRU, one by one in the designated sequence, to see if the symptoms change.

ThinkPad Common Parts List

Keyboard/Auxiliary Input Device Checkout

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

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

If the keyboard cable connections are correct, you can run on TP-2635 the - Keyboard Test by doing the following:

1. Go to the diagnostic menu screen by selecting Test in  the Easy-Setup screen.
2. Press Ctrl+A. The ThinkPad FRU Connections screen appears.  (If the Ctrl+A does not work, triple-click on the icon on the  right bottom corner on the basic diagnostic screen.)
3. Make sure that the keyboard connection is Connected, then press Esc to escape the screen.
4. A layout of the keyboard appears on the screen. Check that when  each key is pressed, the key's position on the keyboard layout on the screen changes to  a black square.

   NOTE: When a Fn key is pressed, a black square briefly appears.

5. Press Ctrl+Pause to end the test.

If the test detect a keyboard problem, do the following one at a time to correct the problem. Do not replace a nondefective FRU

• Reseat the keyboard flexible cable.

• Replace the subcard
• Replace the system board.

TrackPoint III Checkout

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

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

The TrackPoint III does automatic compensations to adjust the pointer sensor. During this process, the pointer moves on the screen automatically for a short time. This self-acting pointer movement can occur when a slight, steady pressure is applied to the TrackPoint III pointer while the computer is powered on or while the system is running, or when re-adjustment is required because the temperature has exceeded its normal temperature range. This symptom does not indicate a hardware problem. No service actions are necessary if the pointer movement stops in a short period of time.

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

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

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

• Reseat the keyboard card cables.
• Replace the keyboard.
• Replace the keyboard (if TP
• 2635 the Sub) card.
• Replace the system board.

Diskette Drive Test

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

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

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

Do the following to select the test device:

1. Select the advanced diagnostics mode and  select Tool , then  select the FDD-1 or FDD-2 icon and  press the spacebar.  A OK mark appears next to the selected icon.  Insert a blank diskette when instructed.
2. Run the diskette drive test.
3. If the controller test detects an error, FRU code 10 appears.  Replace the system board.
4. If the controller test runs without errors,  the drive read/write tests start automatically.
5. If the drive test detects an error, FRU code 50 for FDD-1  or 51 for FDD-2 appears.  If the diskette itself is known to be good, replace the drive.

PC Test Card LED

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

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

1. Select the icon FDD on the TEST MENU . By  doing this, the controller test and the drive  read/write test run.  If the controller test detects an error, FRU code 10 appears.  In this case, replace the system board.
2. If the controller test run without errors,  follow the instructions on the screen and insert a scratch  diskette.
3. If the drive test detects an error, FRU code 50 appears.  If the diskette media are known to be good, replace the drive or the  drive cable.

The following auxiliary input devices may be available for IBM ThinkPad models.

• Numeric keypad
• Mouse (PS/2 compatible)
• External keyboard (with Keyboard/Miniature Mouse cable)

• If you suspect a problem with any of the auxiliary input devices  (listed above), replace the device.

If the problem is not corrected, replace the following FRUs one  at a time to correct the problem.

• Keyboard control card
• System board

• If the computer receives an incorrect keyboard response,  remove other external devices, check the keyboard connections, and recheck  the keyboard responses. If the problem remains, replace the following FRUs  one at a time to correct the problem.

  • Keyboard
  • Keyboard control card
  • System board

  • If a 00030100 error message appears,  power-off the computer and the external devices.  Then power-on the computer before you power-on the external devices.

1. Make sure the printer is correctly connected and is powered-on.
2. Run the printer self-test.

If the printer self-test does not run correctly, the problem is in the printer. Refer to the printer service manual.

If the printer self-test runs correctly, do the following.

1. Verify the port settings in configuration.
2. Install a wrap plug on the port (indicated in configuration)  and run the advanced diagnostic tests.
3. If the advanced diagnostic tests (with the wrap plug installed)  do not detect a failure, replace the printer cable. If the problem is not corrected, replace the system board.

Use the following procedure to isolate a port replicator problem. A 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 replicator.
3. Unplug the AC adapter from the replicator, if attached.
4. Remove the port replicator from the computer.
5. Reconnect the failing device directly to the computer.  (If another device occupies the connector, remove it first.)
6. Go to General Checkout and follow that procedure.
7. If the advanced diagnostic device test does not find an error,  suspect a problem with the port replicator  or the system expansion bus.
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 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.
10. If diagnostic errors appear, replace the replicator or diskette drive attachment unit. If the problem remains after the replacement, replace the system board.
11. 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.

Memory Checkout

DIMM cards are available for increasing memory capacity.

Memory errors might stop system operations, show error messages on the screen, or hang the system.

Use the following procedure to isolate memory problems.

NOTE: Make sure that the DIMM is fully installed into the connector. Both latches must be latched completely. A loose connection can cause error code 195.

1. Power off the computer and remove the DIMM from its  slot (if installed).
2. Press and hold the F1 key, then power on the computer.  Hold the F1 key down until the Easy-Setup screen appears.
3. Select Test and press Enter.
4. Select Memory and press Enter to  run the memory test on base memory. If an error appears, replace the  system board.
5. Power off the computer and reinstall the DIMM, then power on the  computer. Verify the memory size, then test the memory. If an error  appears, replace the DIMM.

If memory problems occur intermittently, make sure the DIMM socket latches are latched completely. If the DIMM latches are securely latched, use the loop option to repeat the test. When the test detects an error, an error log is printed on the printer connected to the parallel port.

• For 2625 365X, XD see 'Error Log'
• For 2635 380
• 385 see 'Error Log'

for more information.

The processing functions are performed by the system board. When a numeric code calls the system board as a FRU, use the following procedure to isolate the problem.

1. Run the system board test to verify the symptom.  This test verifies the system board. If no error is detected, return to Checkout Guide
2. If FRU code 10 appears, replace the system board.
3. Return the test to verify the fix.

If this procedure does not correct the problem, go to Undetermined Problems.

If an LED problem occurs, do the following:

1. Power off the computer.
2. Power 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 that all LEDs turn on.

If the problem remains, replace the following cards one at a time:

• Subcard
• System board

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.

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

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 the battery pack.

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

Power Management Features

Three power management modes are provided by the computer to reduce power consumption and prolong battery power.

Standby Mode

When in standby mode the following occurs:

• The LCD backlight turns off.
• The hard disk motor stops.

Events that cause the computer to enter standby mode:

• Standby requested by the Fn key. (Fn+F3)
• No activity under auto-standby enabled by the  ThinkPad Features program.

Event that causes the computer to exit hibernation mode:

• The power-on switch is operated.

When power is turned on, the hibernation history in the boot record on the hard disk is recognized and system status is restored from the hard disk to resume operation.

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 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.

 

• If the voltage is correct, replace the subcard.
• If the problem is not corrected, replace the system board.
• If the problem is not corrected, go to 'Undetermined Problems' .
• If the voltage is not correct, go to the next step.
• Unplug the AC Adapter cable from the ac power outlet and wait  five minutes or longer to allow the over-voltage protection circuit  to be fully discharged and initialized.
• 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 defective adapter.

Checking Operational Charging

To check operational charging, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer.

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

Checking the AC Adapter (2635-380/385)

1. Power off the computer.

2. Remove the battery pack and measure the voltage between  battery terminals 1 (+) and 4 (-).

    

   Terminal	Voltage (Vdc) / Signal
   1	+0 to +13.5
   2	N/C
   3	Thermal
   4	Ground (-)
   5	Select
   6	A-Ground

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

   • If the voltage is less than +11.0 Vdc, the battery pack has been discharged.  Recharge the battery pack.

   If the voltage is still less than +11.0 Vdc after recharging, replace the battery.

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

   • If the voltage is more than +11.0 Vdc, 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 subcard.

1. Power off the computer and unplug the AC Adapter from the computer.
2. Turn the computer upside down.
3. Remove the DIMM cover and backup battery (see DIMM Card / Backup Battery)
4. Measure the voltage of the backup battery.

   NOTE: Be careful not to measure the wrong side of the backup battery.

 

• 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.

Checking the Backup Battery

1. Power off the computer and unplug the AC Adapter from the computer.
2. Open the keyboard and remove the battery pack.
3. Lift the right-hand section of the black insulator sheet.
4. Locate the backup battery on the system board, shown at 1.

   

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

5. Using a plastic tool, remove the backup battery from the system board.
6. Measure the voltage of the backup battery. Refer to the following table for voltages:

   Wire	Voltage (Vdc)
   +	+2.5 to +3.7
   -	Ground

• If the voltage is correct, replace the system board.
• If the voltage is not correct, the backup battery has been  discharged. Replace the backup battery.
• If the backup battery discharges quickly after replacement,  replace the system board.

Checking the Battery Pack

Battery charging will not start until the Fuel-Gauge shows that less than 95% of the total power remains, with this condition the battery pack will charge to 100% of its capacity. This protects the battery pack from being overcharged or having a shortened life.

Do the following:

1. Power off the computer.

2. Remove the battery pack and measure the voltage between battery terminals 2 (+) and 6 (-).

    

   Terminal	Voltage (Vdc) / Signal
   1	-
   2	+8 to +13.5
   3	-
   4	-
   5	Thermal
   6	Ground (-)

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

  Numeric Error Codes

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.

Beep Symptoms

No-Beep Symptoms

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.

If the problem remains after replacement of the FRUs, go to 'Undetermined Problems'.

FRU Codes

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. See the referenced page before replacing the FRU.

If the problem remains after replacement of the FRUs, go to 'Undetermined Problems'.

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.

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.

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.
