Diagnostic Error Codes

Diagnostic error codes occur if the system recognizes a problem while running the Compaq Utilities TEST program. These error codes help identify possible defective subassemblies.

IMPORTANT:

Retest the system after completing each step. If the problem has been resolved, do not proceed with the remaining steps.

For assistance in the removal and replacement of a particular subassembly, see Removal and Replacement Procedures.
