Chapter 3.2 DIAGNOSTIC ERROR CODES

DIAGNOSTIC error codes occur if the system recognizes a problem while running
the COMPAQ DIAGNOSTICS program (refer to the MAINTENANCE AND SERVICE GUIDE
SUPPORT SOFTWARE for additional information on running the DIAGNOSTICS
software). These error codes help identify possible defective subassemblies.
Tables 3-2 through 3-11 list possible error codes, a description of the error

the problem. After completing each step, run the DIAGNOSTICS program to

reappears, perform the next step, then run the DIAGNOSTICS program again.
Follow this procedure until the DIAGNOSTICS program no longer detects an error
condition.
The error codes appear in an AYY-XX or AAYY-XX format.
A or AA = number that represents faulty assembly
YY = test or action that failed
XX = a specific problem
Example: Error code 610 - 21 shows that the diskette drive failed to get
change line status.
For assistance in the removal and replacement of a particular subassembly, see
