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.
