iv Hardware Maintenance Manual A40 Type 6840 A40P Type 6841 A40i Type 2271: IBM NetVista Computer

Chapter 1. General Checkout

This general checkout procedure is for type 2271/6840/6841 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 “Diagnostics” on page 8.

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:

vType 2271/6840/6841 computers default to come up quiet (no beep and no memory count and checkpoint code display) when no errors are detected by POST.

vTo 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 “Setup Utility program” on page 7).

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

vBefore 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. For more information on how to determine and obtain the latest level BIOS, see “BIOS levels” on page 87.

vIf multiple error codes are displayed, diagnose the first error code displayed.

vIf the computer hangs with a POST error, go to Symptom-to-FRU Indexon page 37.

vIf the computer hangs and no error is displayed, go to “Undetermined problems” on page 75.

vIf an installed device is not recognized by diagnostics, 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 the computer.

7.Check for the following response:

v Readable instructions or the Main Menu.

DID YOU RECEIVE THE CORRECT RESPONSE?

1.At the start of the diagnostic tests, the Module Test Menu is displayed. Normally, all installed devices in the computer are highlighted on the menu.

2.At the start of the diagnostic tests, the main menu appears. From this menu, select System Info, then select Hardware Configuration from the next menu. Normally, all installed devices in the computer are highlighted on this report.

If an installed device is not recognized by diagnostisc, then review the following:

vThe diagnostic code for the device is not in the siagnostic programs. Run the diagnostics provided with that device.

vThe missing device is defective or it requires an additional diskette or service manual.

vAn unrecognizable device is installed.

Chapter 3. Diagnostics 9

vA defective device is causing another device not to be recognized.

vThe SCSI controller failed (on the system board or SCSI adapter).

vUse the procedure in “Undetermined problems” on page 75 to find the problem.

Important:

Some errors are indicated with a series of beep codes (see “Beep symptoms” on page 57).

Type 2271/6840/6841 computers default to come up quiet (no beep and no memory count and checkpoint code display) when no errors are detected by POST. 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 “Setup Utility program” on page 7).

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

The processor is a separate FRU from the system board; the processor is not included with the system board FRU.
