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.
