Start here. IBM's entry procedure for the ThinkPad 510: run the Power-On Self Test or the Advanced Diagnostics, then use the symptom table at the end to pick the next procedure.

Attention Important

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.
  1. Power-off the computer and all external devices.
  2. Check all cables and power cords for correct connection.
  3. 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.

  4. Power-on all external devices.
  5. 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.

  6. Power-on all external devices.
  7. 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.

  8. When the message Starting PC DOS appears, press F5.
  9. When the DOS prompt appears, type cd c:\thinkpad\diags
  10. Press Enter.
  11. Type command
  12. Press Enter to start the advanced diagnostics; then, continue with the next step.
  13. Run the advanced diagnostics tests. For information on how to disable the password, see Power-On Password Override.
  14. Find your symptom below, then go to the appropriate page. Otherwise, see Symptom-to-FRU Index, then go to Undetermined Problems.

Source: Hardware Maintenance Manual Volume 1: Laptop, Notebook, Portable and ThinkPad Computers, p.280

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.

Checking the Installed Devices List #

Source: Hardware Maintenance Manual Volume 1: Laptop, Notebook, Portable and ThinkPad Computers, p.281

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.

Power Systems Checkout #

Source: Hardware Maintenance Manual Volume 1: Laptop, Notebook, Portable and ThinkPad Computers, p.274

To check the system power, do the following.

  1. Power-off the computer.
  2. Remove the battery from the computer.

Power Management Features #

Source: Hardware Maintenance Manual Volume 1: Laptop, Notebook, Portable and ThinkPad Computers, p.275

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

Attention Important

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.

Formatting the Hard Disk Drive #

Source: Hardware Maintenance Manual Volume 1: Laptop, Notebook, Portable and ThinkPad Computers, p.283

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.

Attention Warning

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.

Source: Hardware Maintenance Manual Volume 1: Laptop, Notebook, Portable and ThinkPad Computers, p.283

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.

Attention Important

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

Utilities #

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.

Attention Warning: 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.

Important

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.
