Chapter 5.3 Diagnostic Error Codes
DIAGNOSTIC error codes occur if the system recognizes a problem while running
the COMPAQ DIAGNOSTICS Program.
These error codes help identify possible
defective subassemblies.
Table 5.3 lists all possible error codes, a description of the error
condition, and the action required to resolve the error condition.
In each case, the required action lists prioritized steps necessary to
correct the problem.
After each step is completed, run DIAGNOSTICS to verify
whether the error condition has been corrected.
If the error code reappears,
perform the next step, then run the DIAGNOSTICS Program.
Follow this
procedure until the DIAGNOSTICS Program no longer detects an error condition.
For assistance in the removal and replacement of a particular subassembly, see
Chapter 7, "Removal and Replacement Procedures."
Table 5-3.
