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:
vType 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.
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 “Using the Configuration/Setup Utility
program”on page 23).
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.
vIf multiple error codes are displayed, diagnose the first error code displayed.
vIf the computer hangs and no error is displayed, go to “Undetermined problems”on page 106.
vIf 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:
vReadable instructions or the Main Menu.
DID YOU RECEIVE THE CORRECT RESPONSE?
If NO, continue to 002.
If YES, proceed to 003.
© Copyright IBM Corp. 2000 1

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.
vIf you receive an error, replace the part that the diagnostic program calls out or
go to Chapter 3, “Diagnostics”on page 13.
vIf the test stops and you cannot continue, replace the last device tested.
