S
ystem Beep Codes
When errors occur during a boot routine that cannot be
reported on the monitor, the computer may emit a series
of beeps that identify the problem. The beep code is a pat-
tern of beeps. For example, four beeps means the timer is
not operational. This information is valuable to the Dell
support staff if you need to call for technical assistance.
When a beep code is emitted, write it down on a copy of
the Diagnostics Checklist found in Appendix A, and then
look it up in Table 3-2. If you are unable to resolve the
problem by looking up the meaning of the beep code, use
the system diagnostics to identify a more serious cause. If
you are still unable to resolve the problem, see Chap-
ter 11, “Getting Help,” for instructions on obtaining
technical assistance.
W
arning Messages
A warning message alerts you to a possible problem and
asks you to do something before execution continues. For
example, before you format a diskette, a message may
warn you that you may lose all data on the diskette as a
way to protect against inadvertently erasing or writing
over the data. These warning messages usually interrupt
the procedure and require you to respond by typing a
y
(yes) or
n
(no).
NOTE: Warning messages are generated by either the
application programs or the operating system. See
Chapter 4, “Finding Software Solutions,” and the docu-
mentation that accompanied the operating system and
application programs.
