Diagnostic error codes occur if the system recognizes a problem while
running the Compaq Diagnostic program. These error codes help identify
possibly defective subassemblies.
The following tables list error codes, a description of the error condition,
and the action required to resolve the error condition.
IMPORTANT:
Retest the system after completing each step. If the
problem has been resolved, do not proceed with the
remaining steps.
For the removal and replacement of a particular subassembly, see
Removal and Replacement Procedures.
