Diagnosing
and Solving Problems
One beep indicates that the system has completed its power-on self-test (POST) test. If intermittent beeping
occurs, power off the system and try again. If the beeping persists, see Table 4-2 and Table 4-3. The
following table summarizes problems that may develop during system operation and lists (in sequential order)
suggested corrective actions.
