Diagnostic Error Codes
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.
