  6. Run the advanced diagnostics tests. For information on how to run the diagnostics tests, see Running the Diagnostics. For information on how to disable the password, see Removing the Power-On Password.
  7. Find your symptom in the table in Checkout Guide, and then go to the appropriate page. Otherwise, see Symptom-to-FRU Index, and then go to Undetermined Problems.

Keyboard / Auxiliary Input Device Checkout #

Source: Hardware Maintenance Manual Volume 2: ThinkPad Computers, p.481

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 top system board.

If the keyboard cable connection is correct, run the Keyboard Test by performing the following steps:

  1. Power-off the computer, and then power it on again.
  2. Press the F1 key any time while the POST memory count is proceeding. At the end of the memory test, the Easy-Setup screen appears.
  3. Press the left or right arrow key to select Test and press Enter or position the pointer over the Test icon and click the left click button once.
  4. Press Ctrl+A to enter advanced diagnostics.
  5. Press Ctrl+K to start the keyboard diagnostics test.
  6. Press each key. A shaded box appears in the corresponding key position on the keyboard layout on the screen. Press the key again to remove the box.

    Note: The shaded box appears in Fn only during the first keyboard test of a diagnostics session.

  7. To exit from the test screen, press Esc.

If the tests detect a keyboard problem, perform the following tasks one at a time to correct the problem:

Note: Do not replace a nondefective FRU.

  • Reseat the three cables.
  • Replace the keyboard.
  • Replace the top system board.

The following auxiliary input devices are supported for this computer through the MultiPort II:

  • Numeric keypad
  • Mouse (PS/2 compatible)
  • External keyboard (standard PS/2 or with keyboard/mouse cable)

If any of the above devices do not work, reseat the cable connector and repeat the failing operation. If the problem does not reoccur, recheck the connector. If the problem reoccurs, repeat the operation with a device that is known to be good. If the problem still reoccurs, go to MultiPort II Checkout.

TrackPoint III Checkout #

Source: Hardware Maintenance Manual Volume 2: ThinkPad Computers, p.142

If the TrackPoint III does not work, check the configuration in the Configuration Utility by pressing PgDn to reach the I/O Management screen. If the setting for TrackPoint III is Off, press the left or right arrow to change it to On. If this does not correct the problem, continue with the following procedure:

Note: The TrackPoint III performs automatic compensations to adjust the pointer sensor. During this process, the pointer moves about the screen for a short time. This self-acting pointer movement can occur when a slight, steady pressure is applied to the TrackPoint III pointer when the computer is powered on, when the system is running, or when readjustment is required because the temperature has changed significantly within a short period of time or the temperature is higher than its operating temperature. This symptom does not indicate a hardware problem. No service actions are necessary if the pointer movement stops in a short period of time. However, the TrackPoint III will not stabilize if you apply pressure to it. If pointer movement occurs, you can go into Suspend mode, and then resume normal operation. Resuming or turning the computer on both cause the TrackPoint III to be calibrated, which may correct the problem. If you see continual movement of the pointer, the TrackPoint III is probably defective. In rare cases, the top system board can also cause this problem.

If a click-button problem or TrackPoint III problem occurs, perform the following steps:

  1. Power-off the computer, and then power it on again.
  2. Press the F1 key any time while the POST memory count is proceeding. At the end of the memory test, the Easy-Setup screen appears.
  3. Select an item with the TrackPoint III.
  4. Press either the left or right click button.
  5. Verify that both buttons work correctly.

If either the TrackPoint III or the click button does not work, perform the following tasks one at a time to correct the problem:

Note: Do not replace a nondefective FRU.

  • Reseat the three keyboard cables.
  • Replace the keyboard.
  • Replace the top system board.

Diskette Drive Checkout #

Source: Hardware Maintenance Manual Volume 2: ThinkPad Computers, p.143

Use the following procedure to isolate the diskette problem to a controller, drive, or diskette. For this test, you need a scratch, write-enabled, double-sided, high-density diskette (2.0MB that formats to 1.44MB) that is known to be good.

Infrared Transceiver Checkout #

Source: Hardware Maintenance Manual Volume 2: ThinkPad Computers, p.147

The infrared transceiver is located on the inverter card in the ThinkPad 701C / 701CS. When you run diagnostics on the infrared transceiver, the test is actually checking the top system board, not the infrared transceiver itself. Therefore, complete the following steps before running diagnostics or replacing any FRUs.

If the customer cannot establish a connection between the ThinkPad 701C / 701CS and a remote system, perform the following steps:

  1. Ensure that the device the customer attempted to connect with is an Infrared Data Association (IRDA) compliant device.
  2. Check to make sure that both systems are using the same revision level of the same software.
  3. Check setup options on both systems to ensure that the baud rate and other setup parameters are the same.
  4. Check the Configuration Utility to ensure that the infrared transceiver is assigned to the same serial port that is designated in the application software and that the IRQ assignment is not shared with any other device such as the internal modem or external serial port on the MultiPort II.
  5. Verify that the two systems are in close proximity (less than 1 meter [3.2 feet] apart for IRDA-compliant devices) and that the infrared transceiver window on the ThinkPad 701C / 701CS is aligned with (directly opposite) the remote device's window.
  6. Ensure that the windows on both systems are clean and unobstructed.

If the two systems still will not connect after you have followed the preceding steps and the remote system is another computer with a terminal program (for example, Windows Terminal or Procomm) installed, perform the following tests:

  1. Set up the terminal application on each system to communicate with the infrared transceiver serial port at a speed of 115KB per second.
  2. Type characters on the ThinkPad 701C / 701CS keyboard and check to see whether or not these characters appear on the remote system. (Note that the characters you type will not appear on the ThinkPad 701C / 701CS system.)
  3. Type characters on the remote keyboard and check to see whether or not these characters appear on the ThinkPad 701C / 701CS system.
  4. If characters do not appear in either step 2 or 3 and you are certain that infrared is working correctly on the remote system, replace the inverter card.
  5. If characters do appear, consult the software vendor to ensure that the customer is using a compatible software package and that the setup parameters are correct.

If data transfers between the ThinkPad 701C / 701CS and the remote system are slow or unstable:

  1. Verify that the two systems are in close proximity (less than 1 meter [3.2 feet] apart for IRDA-compliant devices) and that the infrared window on the ThinkPad 701C / 701CS is aligned with the remote device's window.
  2. Ensure that the windows on both systems are clean and unobstructed.
  3. If you are using TranXit, check the IRDELAY parameter in the TRANXIT.INI file in the TRANXIT directory. The parameter should be set to 10.

To run the diagnostics test on the infrared transceiver, perform the following steps:

  1. Power-off the computer, and then power it on again.
  2. Press the F1 key any time while the POST memory count is proceeding. When the memory test is completed, the Easy-Setup screen appears.
  3. Press the left or right arrow key to select Test and press Enter or position the pointer over the Test icon and click the left click button once.
  4. Press Ctrl+A to enter advanced diagnostics.
  5. Select Infrared and press Enter to run the test on the infrared transceiver. Test results will be displayed under the Infrared icon.
  6. If no errors are detected, the OK message appears.
  7. If an error is detected, the FRU code and error description message appear. Go to FRU Codes and replace the FRU.
  8. To exit from the test screen, press Esc.

PCMCIA Checkout #

Source: Hardware Maintenance Manual Volume 2: ThinkPad Computers, p.149

For a more thorough test, use one PCMCIA card in each slot. Perform the following steps to test the PCMCIA slots:

  1. Power-off the computer, and then power it on again.
  2. Press the F1 key any time while the POST memory count is proceeding. When the memory test is completed, the Easy-Setup screen appears.
  3. Press the left or right arrow key to select Test and press Enter or position the pointer over the Test icon and click the left click button once.
  4. Press Ctrl+A to enter advanced diagnostics.
  5. If you are using PC test cards, select Tool to install them. Insert the cards when prompted. (For instructions on installing test cards, see Running the Diagnostics. For instructions on inserting the cards, see Removing PCMCIA Cards.)
  6. Select the PCMCIA icon and press Enter to run the test on the PCMCIA slots. The green LED on the PCMCIA card should turn on when the test runs. (If the green LED does not turn on, see Reading the PC Test Card LED.) Test results will be displayed under the PCMCIA icon.
  7. If no errors are detected, the OK message appears.
  8. If an error is detected, the FRU code and error description message appear. Go to FRU Codes and replace the FRU.
  9. To exit from the test screen, press Esc.

Checking Installed Devices #

Source: Hardware Maintenance Manual Volume 2: ThinkPad Computers, p.167

Installed devices are displayed as dark icons on the diagnostics screen. All other devices are displayed with gray icons.

If a device is installed but the icon appears gray rather than dark, the device is defective. Reseat the device connectors, and then restart diagnostics. 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, if HDD-2 appears in a dark shade when a second hard disk drive is not installed, perform the following steps:

  1. Replace the first device, such as HDD-1.
  2. If the problem persists, replace the relevant system board.

The PCMCIA, System Board, Display, and infrared transceiver icons are always displayed in a dark shade, because the icons represent subsystems of the system board and not attached devices. The parallel port icon is dark except when the diskette drive is attached to the parallel port; in that case, the FDD icon is dark and the parallel port icon is gray. Icons for devices attached through the MultiPort II are dark when the devices are attached, and are gray when the devices are removed from the MultiPort II.

The HDD-1 icon represents the first drive in the system configuration. Similarly, the HDD-2 icon represents the second drive, attached to the docking station.

Power Systems Checkout #

Source: Hardware Maintenance Manual Volume 2: ThinkPad Computers, p.145

To verify the symptom of the problem, power-on the computer using each of the power sources available as follows:

  1. Remove the battery.
  2. Connect the AC adapter and check that power is supplied by pressing the power switch.
  3. Disconnect the AC adapter and install the charged battery; then, check that power is supplied from the battery by pressing the power switch.

Note: The battery is charged only while the computer is powered-on (the computer can be in the suspend mode). The battery cannot be charged if the computer is powered-off.

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

Reading Status Indicators #

Source: Hardware Maintenance Manual Volume 2: ThinkPad Computers, p.165

The system status indicators show the current computer status in different colors (green and yellow).

Reading the Battery Status

If the computer is using the battery, the Battery Status field in the Configuration Utility indicates whether the battery is OK or low. If the computer is using external power, this field indicates whether the battery is fully charged or still charging. The battery fuel gauge provides a visual indication of the battery power level.

Checking the AC Adapter #

Source: ThinkPad 701C / 701CS (2630) Hardware Maintenance Manual, p.11

Check the AC adapter if the computer fails only when the AC adapter is used, or if the battery does not charge when the AC adapter is attached and the computer is on or in suspend mode.

  • If the power problem occurs only when the MultiPort II is used, replace the MultiPort II.
  • If the power-on indicator does not turn on, check the AC adapter for correct continuity and installation. If the connection is suspect, replace the AC adapter.
  • If the operational charge does not work, go to Power Related Symptoms.

Note: Several types of AC adapters can be supplied with the ThinkPad 701C / 701CS. The procedure for checking them is the same.

  1. Unplug the AC adapter cable from the computer and measure the output voltage at the plug of the AC adapter cable. See the following figure.

    DC plug of the adapter cable with pins 1 and 2 labelled for measuring the output voltage

    Pin Voltage (Vdc)
    1 +15.5 to +17.0
    2 Ground
  2. If the voltage is not correct, replace the AC adapter.

    Note: In rare cases, the problem may be in the AC adapter even when the voltage is correct. If an AC adapter is available, try replacing the computer's AC adapter.

  3. If the voltage is correct, replace the top system board. If this does not correct the problem, go to Undetermined Problems.

Note: An audible noise from the AC adapter does not always indicate a defective adapter.

Checking the Battery Pack #

Source: ThinkPad 701C / 701CS (2630) Hardware Maintenance Manual, p.11

Perform the following steps to check the battery:

Important please READ - see Safety Notice 7

Attention Though main batteries have low voltage, a shorted or grounded battery can produce enough current to burn combustible materials or personnel.

Understanding the Power-On Self-Test #

Source: ThinkPad 701C / 701CS (2630) Hardware Maintenance Manual, p.31

Each time you power-on the computer, the power-on self-test (POST) is initiated. The POST takes up to 90 seconds to complete, depending on the options installed.

The POST checks the following items: system boards, memory, display, keyboard, diskette drive, hard disk drive, parallel port, and serial port.

To start the POST, power-on the computer. The following actions will happen:

  1. If a critical error occurs during the POST, the system halts. The system might beep or display a message.

    If the POST cannot be completed successfully, an error code appears on the display, and you are prompted to press Esc or Enter. If you press Esc, the computer bypasses the error and attempts to complete the POST. If you press Enter, the computer displays the Configuration Utility window. You can then try to correct the error. (See Running the Diagnostics.)

  2. The computer issues one short beep when the POST ends successfully.
  3. The computer attempts to load the operating system as customized. If the computer does not find an operating system, it displays a graphic message requesting that you insert a bootable diskette in the diskette drive and press F1 to resume operation.

External Display Self-Test #

Source: Hardware Maintenance Manual Volume 2: ThinkPad Computers, p.480

If the display problem occurs only when using an external display, use the following instructions to correct the problem.

Note: Before you replace a display, check the following list to see if it is connected correctly.

  • 8506 and 8508 displays must be connected to an Image Adapter/A or an Image-I Adapter/A.
  • 63XX and 85XX systems support either 63XX or 85XX displays.
  • 85XX systems with an XGA-2 adapter support 95XX displays.
  • 95XX systems support either 63XX, 85XX, or 95XX displays.
  • ThinkPad models support either 85XX or 95XX displays.

If the screen is rolling, replace the display assembly. If that does not correct the problem, replace FRUs in the following order until the problem goes away:

  1. Video card
  2. Display adapter (any type)
  3. System board
  4. Bus adapter (if used)

If the screen is not rolling, run the display self-test as follows:

  1. Power-off the computer and display.
  2. Disconnect the display signal cable.
  3. Power-on the display.
  4. Set the contrast to its maximum position.
  5. Set the brightness control to the center detent position.

Check for the following conditions:

  • You should be able to vary the screen intensity by adjusting the contrast and brightness controls.
  • The screen should be white or light gray, with a black margin (test margin) on the screen.

    Note: The location of the test margin varies with the type of display. The test margin might be on the top, bottom, or one or both sides.

If you do not see a test margin on the screen, replace the display. If there is a test margin on the screen, replace the system board.

Error codes Numeric Error Codes

The Symptom-to-FRU Index contains tables that list causes of symptoms. The most likely cause is listed first. Use this index to help you decide which FRUs to have available when servicing a computer.

Important please READ - see 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.

Perform the FRU replacement or actions in the sequence shown in the “FRU / Action” columns. If the replacement FRU did not solve the problem, put the original FRU back in the computer.

Notes:

  1. Before replacing the top and bottom system boards, try reseating the boards. If reseating the boards does not correct the problem, replace the boards.
  2. If possible, install the latest level of BIOS available before replacing any FRU.

Before completely reassembling a computer that has been repaired, try to reboot the computer to check the repairs that have been completed. However, when you reboot without the keyboard attached, the computer will display error codes 8603, 8613, and 86XX.

Use displayed numeric error codes to determine the system problem. If numeric error codes are not available, use the other symptom tables that describe specific symptoms. If the symptom is not listed, go to Undetermined Problems.

Safety Notice 7 #

Source: ThinkPad 701C / 701CS (2630) Hardware Maintenance Manual, p.12

Warning 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.
