What this machine shipped with, from a teardown-level survey and IBM's own product records. Use it to check a candidate machine before ordering parts.

The ThinkPad 510Cs is a color subnotebook offering improved performance and display capabilities over the earlier 500.

  The Advanced Diagnostics program is shipped on the hard disk drive. An external diskette drive must be attached to the computer to run the diagnostics program from a diskette. The Advanced Diagnostics diskette, part number S83G8095, contains the same Advanced Diagnostics program shipped on the hard disk drive. If the diagnostics are not on the hard disk drive and an external diskette drive is not attached to the computer, do the following.

1. Run the POST (Power-On Self Test).
2. If you receive an error, go to 'Symptom-to-FRU Index' .
3. If you suspect an undetermined problem, go to 'Undetermined Problems' .

4. Power-off the computer and all external devices.

5. Check all cables and power cords for correct connection.

6. If you are going to run the advanced diagnostics from the diskette  drive; insert the Advanced Diagnostics diskette into the diskette drive,  then continue with step 4.

   If you are going to run advanced diagnostics from the hard disk drive, go to step 6.

7. Power-on all external devices.
8. Power-on the computer and check for one short beep at the end of POST with a clear and readable diagnostics menu displayed. If you did not get the correct responses, go to 'Symptom-to-FRU Index'.  If you received the correct responses, go to step 12.
9. Power-on all external devices.
10. Power-on the computer and check for one short beep at the end of POST with a clear and readable diagnostics menu displayed. If you did not get the correct responses, go to 'Symptom-to-FRU Index'. NOTE: The following two steps are important because they prevent programs which might affect the diagnostic tests from being loaded into memory.  press F5.
11. When the DOS prompt appears,   type cd c:\thinkpad\diags
    • Press Enter.

    type command

    • Press Enter to start the advanced diagnostics; then, continue with the next step.
12. Run the advanced diagnostics tests. For information on how to disable the password, see 'Power-On Password Override'.
13. Find your symptom below, then go to the appropriate page.  Otherwise, see 'Symptom-to-FRU Index', then go to 'Undetermined Problems'.

NOTE: For information about diagnostics, error messages, passwords, and other tests and service checks, go to 'Related Service Procedures'.

• 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 green LED on the PCMCIA test card lights when the PCMCIA test is running. If the LED does not go on, check that the card is installed correctly by reseating the card. (For the docking station, if it still does not light after reseating, try using another slot for the test.) If the LED still does not go on and the test fails, replace the FRU shown in the diagnostic error code.

If an adapter or device is missing from the Installed Devices list and you are able to add it to the list, do so and continue with the diagnostic tests.

If an adapter or device is missing from the installed devices list and you cannot add it to the list, you might have one of the following conditions:

• The diagnostic code for the missing device is not on your Advanced  Diagnostics diskette.
• The missing device is a 3.5-Inch External Diskette Drive Adapter, or  another unrecognizable adapter.
• The missing device is defective.
• The adapter or device is not an IBM product.

If the number of drives installed in the computer differs from the number shown in the installed devices list, an error can occur during the diagnostic tests. Restart the computer and correct the drive information in the Set Configuration menu before running the diagnostic tests.

1. Press 1 (RUN TESTS MULTIPLE TIMES), then  press Enter.
2. Select the device you suspect has a failure, then press Enter.
3. Select the number of times to run the test; then press Enter.
4. Press N (WAIT EACH TIME AN ERROR OCCURS (Y/N)?), then press Enter.
5. Follow any instructions on the display and select all available tests.

   NOTE: Do not press any keys during the keyboard test.

6. To end (RUN TEST CONTINUOUSLY), press and hold Ctrl; then press Pause. The computer  completes testing and returns to the Installed Devices menu.

To check the system power, do the following.

1. Power-off the computer.
2. Remove the battery from the computer.
3. Check the battery voltage. The voltage should be a minimum of 10.8  Vdc. If the voltage is not correct, try recharging the battery  pack. If the voltage is correct, continue with the next step to  test the AC adapter voltage.
4. Unplug the AC adapter from the computer.
5. Measure the voltage at the points shown.

If the voltage is not correct, replace the AC adapter.

If the voltage is correct, go to 'Undetermined Problems'.

Press Func+F3 to select Power Management setup (any time after the computer is powered-on).

  Before using the power saving features, be sure to read and observe the following precautions:

• If you enter Suspend or Hibernate mode with a diskette inserted in  the diskette drive, the same diskette must be installed in the drive  before attempting to resume normal operation.

• If you enter Suspend or Hibernate mode with a PCMCIA  card inserted in the PCMCIA slot, the same PCMCIA card must be installed  in the slot before attempting to resume normal operation.

  Hibernate mode does not save/restore the status of PCMCIA cards. When  you resume normal operation from Hibernate mode, the PCMCIA card is no  longer configured and will not be recognized by the computer.

  • If the computer is connected to a Local Area Network (LAN) that  periodically polls for station activity, the LAN-connection might be  terminated while the computer is in Suspend or Hibernate mode. Any further  attempt to access the network results in a brief delay and the computer  appears to hang (up to 1 minute, depending on the network). After the  delay, an error is displayed. Follow the instructions on the screen to  restore normal operation.
  • Any software program that was running over the LAN is not re-entered  when you resume normal operation from Hibernate or Suspend modes.

The Advanced Diagnostics diskette contains diagnostic programs. The diskette is intended to test only IBM products. Non-IBM products, prototype cards, or modified options can give false errors and invalid computer responses.

To start advanced diagnostics from the Advanced Diagnostics diskette, do the following.

1. Insert the Advanced Diagnostics diskette into the diskette drive.
2. Power-on all external devices.
3. Power-on the computer. (The advanced diagnostics program will load  from the diskette drive.)

To start advanced diagnostics from the hard disk drive, do the following.

1. Power-on all external devices.

2. Power-on the computer.

   NOTE: Some programs cause the diagnostic tests to give inaccurate results.  The following steps prevent these programs  from being loaded into memory while starting the advanced diagnostics.

   • When the message Starting PC DOS appears,

   press F5.

   • When the DOS prompt appears, type cd c:\thinkpad\diags

     • Press Enter.

     • Type command

       • Press Enter to start the advanced diagnostics program.

Each time you power-on the computer, the POST is initiated. The POST takes up to 15 seconds to complete, depending on the options installed.

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

To start the POST, power-on the computer. You hear one short beep when the POST successfully ends.

If the POST cannot be completed successfully, an invalid configuration error message appears. If F1 is pressed, the system bypasses the error and attempts to complete POST. Press F1 to continue or Press F2 to go to Setup.

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.

   • If the problem remains, replace the Power Card.
   • If this does not solve the problem, replace the system board.

Hard disk drives normally contain tracks in excess of their stated capacity to allow for defective tracks. The user is notified by a diagnostic message when the defect limit has been reached and service is recommended.

The Advanced Diagnostics Format program is different from the operating system format program.

  All data on the selected hard disk drive is destroyed during a format operation or surface analysis.

Before the customer can transfer information from the backup diskettes to the hard disk drive, the hard disk drive must be formatted using the operating system format program. Have the customer refer to the operating system manual for a description of the hard disk preparation commands.

After formatting the hard disk drive, copy the System files from the Advanced Diagnostics diskette to the hard disk drive.

Use the following steps to create an error log, run the diagnostic tests, and automatically record any error messages in an error log. This procedure is normally used to diagnose an intermittent problem.

NOTE: The errors must be logged to a diskette drive or to a printer. If recording errors on a diskette, use a copy of the Advanced Diagnostics diskette that is not write-protected. Do not run any diskette tests when logging to a diskette drive. Do not run a parallel port test when logging to a printer.

1. Insert the Advanced Diagnostics diskette into the diskette drive.
2. Press 0 (SYSTEM CHECKOUT) , then press Enter .
3. Depending on the options installed in the  computer, questions about attached devices might  appear on the display. Answer as required; then press Enter .
4. Press Y or N (IS THE LIST  CORRECT (Y/N)?) , then press Enter .
5. Press 2 (LOG UTILITIES) , then press Enter .
6. Press 0 (START ERROR LOG) , then press Enter .
7. Press 0 or 1 (LOG TO DISKETTE, OR PRINTER  (0/1)?) , then press Enter .
8. If you are logging to diskette,  press A (ENTER THE DRIVE ID FOR ERROR LOG?) ,  then press Enter .
9. Press 9 (END LOG UTILITIES) , then press Enter .

The subdirectory C:\THINKPAD\DIAGS on the hard disk drive contains the ThinkPad 510 Diagnostics programs.

If the hard disk drive is reformatted or the files in the subdirectory on the hard disk drive are corrupted, use the Advanced Diagnostics diskette to restore the diagnostic programs.

  The following is required to complete this procedure:

• DOS must be installed on the hard disk drive.
• An external diskette drive must be attached to the computer.

1. Power-on the computer; then, insert the Advanced Diagnostics diskette.

2. At the DOS prompt, type

   A:UINSTALL

   then press Enter.

   • Select Install ThinkPad 510 Diagnostics from the menu. The  files are copied from the diskette to the THINKPAD\DIAGS subdirectory on  drive C.

The computer has two setup options that allow you to specify how the computer operates. The System Parameters (Ctrl+Alt+F3 from the DOS prompt or the Diagnostic Menu) provide access to the power management parameters and the following system elements.

• Time
• Date
• Password
• Personalization
• Diskette drive
• Hard disk drive
• Cache
• Parallel port
• ISO Monitor
• Clock Multiplier

Press the key combination for the setup program you want to start.

Press Esc to display the Exit Menu.

The system is configured with several utility programs. These programs provide added function that enhances the usability of the system. These programs should be backed up to prevent loss of data. Use the Diskette factory in Microsoft Windows to make a backup copy of the Advanced Diagnostics diskette. The utility programs are:

SIMUL Allows you to enable/disable simultaneous display on both the LCD and external monitor.

NOTE: The computer does not enter Suspend/Resume while in the Simultaneous mode. You must exit Simultaneous mode before Suspend/Resume is allowed. Also, the Func + F7 function is not recognized until you exit the Simultaneous mode.

EPP2 Provides Enhanced Parallel Port Utility. This utility needs to be added to the AUTOEXEC.BAT and CONFIG.SYS if the option attached to the parallel port supports the enhanced parallel port mode.

PHDISK Prepares the hard disk drive for the hibernation feature, including formatting and the marking of defective areas. A partition is reserved on the hard disk drive to save data before the computer enters Hibernation mode.

  Running this utility causes loss of data on the hard disk drive. It is important that the customer backup all data prior to using this utility.

Run the PHDISK utility if you change the operating environment, reformat the hard disk drive, or add additional memory.

PCMCIA Drivers IBM2SS01.SYS and PCMCIA.SYS provide the ability to use PCMCIA cards in an OS/2 environment.
