Other Symptoms

Symptom / Error Errors occur only when Port Replicator is used. PCMCIA slot pin is damaged. FRU / Action in Sequence See Port Replicator Checkout on page 36. PCMCIA Slot Assembly
Note: If you cannot find a symptom or error in this list and the problem remains, see Undetermined Problems on page 51.

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 be considered only 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.

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 nondefective 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. (See Power Systems Checkout on page 33.) 1. Power off the computer. 2. 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. 3. Remove or disconnect all of the following devices. a. Non-IBM devices b. Devices attached to the expansion bus connector c. Printer, mouse, and other external devices d. Battery pack e. Hard disk drive f. Diskette drive g. DIMM card h. PC Cards 4. Power on the computer. 5. Determine if the problem has changed. 6. If the problem does not occur again, reconnect the removed devices one at a time until you find the failing FRU. 7. If the problem remains, replace the following FRUs one at a time. Do not replace a non-defective FRU. Subcard System board

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 shades 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 an FDD-1. 2. If the problem remains, replace the system board. 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 the devices. The FDD-1 icon represents the first drive in the system configuration for each type of device. For Model ThinkPad 720 and 720C, FDD-1 represents an external diskette drive attached through the external diskette drive connector. Similarly, the FDD-2 icon represents the second drive, usually attached through a port replicator.

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 shades 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 an FDD-1, an HDD-1, or a PCMCIA-1. 2. If the problem remains, replace the system board. The PCMCIA-1, 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 the devices. The FDD-1, HDD-1, or PCMCIA-1 icons represent the first drive in the system configuration for each type of device. Similarly, the FDD-2 or PCMCIA-2 icons represent the second drive, usually attached through a port replicator or an expansion unit. The HDD-2 icon represents the hard disk drive in the UltraBay. The HDD-3 and HDD-4 icons represent the hard disk drive, attached through an expansion unit.

Name and phone number of servicer Date of service Date when part failed Date of purchase Failure symptoms, error codes appearing on display, and beep symptoms Procedure index and page number in which failing FRU was detected Failing FRU name and part number Machine type, model number, BIOS level, 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 Notes: 1. Check the ECAs (Engineering Change Announcements) of the device that pertain to the system failure before billing the customer. 2. 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 that the system was subjected to stresses beyond normal use:
Important Notes The following is not covered under warranty: LCD panel cracked from the application of excessive forces, shock, or from 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 improper insertion of a PCMCIA Card or the installation of an incompatible card Damage caused by foreign material in the FDD or UltraBay Diskette drive damage caused by the diskette drive cover being pressed or by the insertion of diskettes with multiple labels Damaged or bent diskette eject button CD-ROM drive damage caused by excessive forces shock, or by being dropped Fuses blown by the attachment of a nonsupported device Forgotten computer or hard disk password (making the computer or hard disk unusable) If the following symptoms are present, they may indicate damage caused by nonwarranted activity: Missing parts might be a symptom of unauthorized service or modification. HDD spindles can become noisy from being subjected to excessive force or from being dropped. I9990303 errors can be caused by exposure to strong magnetic fields.

FDD-1 represents a diskette drive in the UltraBay. FDD-2 represents the port replicator, expansion unit, or diskette drive attached through the external diskette drive connector.
Warning: Make sure that the diskette does not have more than one label attached to it. Multiple labels can cause damage to the drive or cause the drive to fail. Do the following to select the test device: 1. Select the advanced diagnostics mode and select Tool; then select FDD-1 or FDD-2 and press the Spacebar. A mark appears next to the selected icon. 2. Press Enter. 3. Insert the blank diskette when instructed. 4. Type Y (Yes) to the question on the screen. 5. Select FDD-1 or FDD-2 and press Enter to run the diskette drive test. 6. If the controller test detects an error, FRU code 10 appears. Replace the system board. 7. If the controller test runs without errors, the drive read/write tests start automatically. 8. 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. 9. If FDD-2 test detects an error, move the drive to the computer's diskette drive connector directly, if possible, and test it again as FDD-1.
If no errors occur in the FDD-1 position, the drive is not defective. Go to Port Replicator Checkout on page 428 to isolate the replicator problem. 10. If the drive is attached through an Expansion Unit, go to the service manual of the Expansion Unit to isolate the problem. 11. If the drive is attached through a Diskette Drive Attachment Unit, replace the unit. 12. If no error occurred when testing the formatted diskette, suspect the diskette that was used when the customer reported the problem. If an error occurs when the external diskette drive is attached through the external diskette drive connector and there is not a diskette drive in the UltraBay, reseat the connector on the video card. If the error persists, reseat the external diskette drive connector. If the error persists, replace the following FRUs one at a time: 1. External diskette drive kit 2. Video card 3. External diskette drive connector
If an LCD information panel problem occurs, do the following: 1. Power off the computer. 2. Power on the computer. 3. All the icons in the LCD information panel appear for a moment soon after the computer is powered on. Verify that all icons appear correctly. If some of the icons do not appear, replace the keyboard. If the problem persists, replace the video card.

Fan Checkout

To check the fan, do the following: 1. Turn off the computer. 2. Remove the following FRUs (see FRU Removals and Replacements on page 454): a. Diskette drive/CD-ROM drive b. Battery pack c. Hard disk drive d. Top cover e. Keyboard unit 3. Attach the AC Adapter to the computer. 4. Applying a short across the two pads with a screw driver as shown below, turn on the computer.
5. Listen for the fan. If the fan does not run, replace it.

If the voltage is less than +4.0 V dc, replace the DC/DC card. If the voltage is still low, replace the system board.
If the voltage is more than +4.0 V dc, power-off the computer, replace the standby battery, and go to the next step. Ensure that the AC Adapter is plugged into the computer; then power on the computer. Charging of the standby battery starts immediately. A depleted battery needs approximately 30 minutes to be recharged to the operational voltage of +3.5 V dc. Unplug the AC Adapter. Verify the standby battery function by removing and installing the battery pack during suspend mode. Note: Removing and installing the battery pack during suspend mode should be done within one minute. If the system does not resume after a charged battery pack is installed, replace the DC/DC card. If replacing the DC/DC card does not resolve the problem, replace the system board.
If a common device problem is suspected, see the appropriate power supply check in the following list: Port Replicator Checkout External Display Self-Test
Port Replicator Checkout: Use the following procedure to isolate a port replicator problem.
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 is already connected to the computer, remove it first.) 6. Go to the Running the Diagnostics on page 449 and run the diagnostics. 7. If the advanced diagnostic device test does not find an error, suspect a problem with the port replicator of 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 FDD-2 device test on the failing device with a scratch diskette 10. If diagnostic errors appear, replace the replicator or diskette drive attachment unit.
If the problem persists after the replacement, replace the system board. 11. If power problems appear only when the replicator is used, replace the replicator.
occurs only when using an external display, use the following instruction to correct the problem. Note: Before you replace a display, check that the 95XX systems support either 63XX, 85XX, or 95XX displays to see if it is connected correctly. If the screen is rolling, replace the external display. If that does not correct the problem, replace the FRUs in the following order until the problem goes away: 1. Video card 2. System board 3. Bus adapter (if used) If the screen is not rolling, run the display self-test as follows: 1. 2. 3. 4. 5. Power-off the computer and display. Disconnect the display signal cable. Power-on the display Set the contrast to its maximum position. Set the brightness control to the center detent position.

This section contains information about removals and replacements. Do not damage any parts. Only certified and trained personnel should service the computer. The arrows in this section show the direction of movement to remove a FRU, or to turn a screw to release the FRU. The arrows are marked in numeric order, in square callouts, to show the correct sequence of removal. When other FRUs that must be removed before the failing FRU is removed, they are listed at the top of the page. To replace a FRU, reverse the removal procedure and follow any notes that pertain to replacement. See Locations on page 607 for internal cable connections and arrangement information. When replacing a FRU, use the correct screw size, as shown in the procedure. Safety Notice 1: Translation on page 8 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 short circuits. Safety Notice 3: Translation on page 10 The battery pack contains small amounts of nickel. Do not disassemble it, throw it into fire or water, or short-circuit it. Dispose of the battery pack as required by local ordinances or regulations. Safety Notice 8: Translation on page 14 Before removing any FRU, power-off the computer, unplug all power cords from electrical outlets, remove the battery pack, and then disconnect any interconnecting cables. An electrostatic discharge (ESD) strap must be used to establish personal grounding.
Note If the customer has locked the eject lever with security screws, remove the screws first.

General Preparation

Note: In this manual, port replicator means the SelectaDock Base Model I or SelectaBase 770. SelectaDock means the SelectaDock III and the SelectaDock Docking System means the port replicator and SelectaDock when docked together as one unit. 1. The SelectaDock III supports the ThinkPad 760E, 760ED, 760EL, 760ELD, 760XD, 760XL, 765D, 765L, and 770. When any other model is docked to the SelectaDock III, a beep sounds. Check which model of the ThinkPad is docked to the SelectaDock III before maintenance. 2. Check that the port replicator is correctly docked (connected) to the SelectaDock III. 3. Check that the computer is correctly docked (connected) to the SelectaDock Docking System. 4. Dock a computer to the port replicator has no problem. If there is any problem with the SelectaDock Docking System, replace the port replicator. 5. If possible, make sure that there are no hardware setting conflicts, such as interrupt levels, memory addresses, DMA channels, and I/O addresses. 6. If the PCI or the ISA card is installed, check that the card is supported by the computer. 7. Check that the SCSI ID is set correctly. 8. Test and correct any computer problems before you test it with the SelectaDock Docking System. Use the computer documentation to resolve any computer problems. 9. Test the computer with the external keyboard, external monitor, mouse, and parallel and serial device connectors. (Use the keyboard/mouse connector to test the external keyboard and mouse.) If no problems are found, connect the external keyboard, mouse, parallel and serial devices to the SelectaDock Docking System. Then connect the SelectaDock Docking System to the computer and test it. 10. If external devices are attached to the SelectaDock Docking System, such as an audio amplifier, check the device by referring to the manual shipped with it. 11. If the user did not bring the computer with a SelectaDock Docking System when service is needed, use a computer that works correctly with the SelectaDock Docking System.
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. Important When the problem determination procedure in the operation manual that is supplied with the adapter or device says Have the system unit serviced, this means both the computer and the SelectaDock Docking System. 1. Obtain the failing symptoms in as much detail as possible. 2. Verify the symptoms by attempting to re-create the failure by running the diagnostic test or by repeating the same operation. Note: To run the diagnostics, refer to the diagnostics section of of the computer you are servicing. 3. 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.

This section contains information on removals and replacements, as well as locations. The arrows in the removals and replacements show the direction of movement to remove a field replaceable unit (FRU), or to turn a screw to release the FRU. The arrows are marked in numeric order to show the correct sequence of removal. When other FRUs must be removed before the failing FRU is removed, they are listed at the top of the page. Go to the removal procedure for each FRU listed, remove the FRU, and then continue with the removal of the failing FRU. To replace a FRU, reverse the removal procedure and follow any notes that pertain to replacement. See Locations on page 673 for internal cable connections and arrangement information. Safety Notice 8: Translation on page 14 Before removing any FRU, power-off the computer, unplug all power cords from electrical outlets, remove the battery pack, and then disconnect any interconnecting cables. Note: You must use an electrostatic discharge (ESD) strap to establish personal grounding.
