Removal & Replacement |
Diagnostic error codes occur if the system recognizes a problem while running the Compaq Utilities TEST program. These error codes help identify possible defective subassemblies.
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.
Click on the desired error code range or corresponding test for a list of descriptions of each error condition and actions required to resolve the error condition.
