TROUBLESHOOTING Diagnostic Error Codes
Diagnostic error codes
occur if the system recognizes a problem while running the Compaq Utilities program. These
error codes help identify possibly defective subassemblies.
Tables listed on this page give possible error codes,
descriptions of each error condition, and actions 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 assistance in the removal and replacement of a
particular subassembly, see Removal and Replacement
Procedures.
