Chapter 1. General checkout

This general checkout procedure is for type 6836, 6846 computers.

Attention:

The drives in the computer you are servicing might have been rearranged or the drive startup sequence changed. Be extremely careful during write operations such as copying, saving or formatting. Data or programs can be overwritten if you select an incorrect drive.

Diagnostic error messages appear when a test program finds a problem with a hardware option. For the test programs to properly determine if a test Passed, Failed or Aborted, the test programs check the error-return code at test completion. See Chapter 3, “Diagnostics” on page 13.

General error messages appear if a problem or conflict is found by an application program, the operating system, or both. For an explanation of these messages, refer to the information supplied with that software package.

Notes:

v Type 6836, 6846 computers default to come up quiet (no beep and no memory count and checkpoint code

display) when no errors are detected by POST.

v To enable beep and memory count and checkpoint code display when a successful POST occurs, do the following:

1. Select Start Options in the Configuration/Setup Utility program (see “Using the Configuration/Setup Utility

program” on page 23).

2. Set Power-On Self-Test to Enhanced.

v Before replacing any FRUs, ensure that the latest level of BIOS is installed on the system. A down-level BIOS

might cause false errors and unnecessary replacement of the system board.

v If multiple error codes are displayed, diagnose the first error code displayed. v If the computer hangs and no error is displayed, go to “Undetermined problems” on page 106. v If an installed device is not recognized by the diagnostics program, that device might be defective.

001

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

2. Check all cables and power cords.

3. Make sure the system board is seated properly.

4. Set all display controls to the middle position.

5. Power-on all external devices.

6. Power-on all external devices.

7. Power-on the computer.

8. Check for the following response:

v Readable instructions or the Main Menu.

DID YOU RECEIVE THE CORRECT RESPONSE?

If NO, continue to 002.

If YES, proceed to 003.

002

If the Power Management feature is enabled, do the following:

1. Start the Configuration/Setup Utility program (see “Starting the Configuration/Setup Utility program” on page 23.)

2. Select Power Management from the Configuration/Setup Utility program menu.

3. Select APM.

4. Be sure APM BIOS Mode is set to Disabled. If it is not, press Left Arrow (})or

Right Arrow (Æ) to change the setting.

5. Select Automatic Hardware Power Management.

6. Set Automatic Hardware Power Management to Disabled.

7. If the problem persists, continue to 003.

003

Run the Diagnostic programs. If necessary, refer to “Starting the diagnostic programs” on page 15.

v If you receive an error, replace the part that the diagnostic program calls out or

go to Chapter 3, “Diagnostics” on page 13.

v If the test stops and you cannot continue, replace the last device tested.

POST

When you turn on the computer, it performs a series of tests to check the operation of system components and some of the options that are installed in the computer. This series of tests is called the power-on self-test or POST.

If POST finishes without detecting any problems, the first window of your operating system or application program appears.

Notes:

1. If you have a power-on password set, you must type the password and press Enter, when prompted, before POST will continue.

2. A single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After you correct the cause of the first error message, the other error messages usually will not occur the next time you run the test.

POST beep code descriptions

The possible types of beep codes that your system might emit are:

Repeating long beeps

Indicates that a memory error has occurred. Ensure that all DIMMs are correctly installed.

One long beep and two short beeps

Indicates that a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. Ensure that the video adapter is correctly installed.

Small computer system interface messages (some models)

The following table lists actions to take if you receive any error message.

Note: If your system does not have a hard disk drive, ignore any message that

indicates that the BIOS is not installed.

You will get these messages only when running the SCSISelect Utility.

Table 3. SCSI messages

SCSI Messages Description

All One or more of the following might be causing the problem.

v A failing SCSI device (adapter or drive) v An improper SCSI configuration v Duplicate SCSI IDs in the same SCSI chain v An improperly installed SCSI terminator v A defective SCSI terminator v An improperly installed cable v A defective cable

Action: Verify that:

v The external SCSI devices are turned on. External SCSI devices must be turned on before

the computer.

v The cables for all external SCSI devices are connected correctly. v The last device in each SCSI chain is terminated properly. v The SCSI devices are configured correctly.

If the above items are correct, run the diagnostic programs to obtain additional information about the failing device.

IBM Enhanced Diagnostics

The system diagnostic programs are stored on the Device Drivers and IBM Enhanced Diagnostics CD. These programs are the primary method of testing the major

components of your computer.

Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel.

Sometimes the first error to occur causes additional errors. In this case, the computer displays more than one error message. Always follow the suggested action instructions for the first error message that appears.

The following sections contain the error codes that might appear in the detailed test log and summary log, when running the diagnostic programs.

The error code format is as follows:

fff-ttt-iii-date-cc-text message

where: fff is the three-digit function code that indicates the function being tested

when the error occurred. For example, function code 089 is for the microprocessor.

ttt is the three-digit failure code that indicates the exact test failure that was

encountered. (These codes are for trained service personnel and are described in the Hardware Maintenance Manual.)

iii is the three-digit device ID. (These codes are for trained service personnel

and are described in the Hardware Maintenance Manual.)

14 Hardware Maintenance Manual: IBM IntelliStation Type 6836, 6846

date is the date that the diagnostic test was run and the error recorded. cc are the check digits that are used to verify the validity of the information. text message

is the diagnostic message that indicates the reason for the problem.

Text messages

The diagnostic text message format is as follows:

Function Name: Result (test specific string)

where:

Function Name

is the name of the function being tested when the error occurred. This corresponds to the function code (fff) given in the previous list.

Result can be one of the following:

Passed

Failed This result occurs when the diagnostic test discovers an error. User Aborted

This result occurs when the diagnostic test completes without any errors.

This result occurs when you stop the diagnostic test before it is complete.

Not Applicable

This result occurs when you specify a diagnostic test for a device that is not present.

Aborted

This result occurs when the test could not proceed because of the system configuration.

Warning

This result occurs when a possible problem is reported during the diagnostic test, such as when a device that is to be tested is not installed.

Test Specific String

is additional information that is used to analyze the problem.

Starting the diagnostic programs

The IBM Enhanced Diagnostics programs will isolate your computer hardware from software that you have installed on your hard disk drive. The programs run independently of the operating system, and must be run either from a CD or diskette. This method of testing is generally used when other methods are not accessible or have not been successful in isolating a problem suspected to be hardware related.

A Device Drivers and IBM Enhanced Diagnostics CD comes with your computer. You can also download the latest image of the diagnostics from http://www.ibm.com/pc/support on the World Wide Web.
