Warning 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
floppy, a message may warn you that you may lose all data on the floppy 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 y (yes) or n (no).
NOTE: Warning
messages are generated
by either your application
programs or your
operating system. See
"Software Problems" and
the documentation that
accompanied your
operating system and
application programs.
Diagnostics Messages
When you run a test group or subtest in the Dell Diagnostics, an error
message may result. These particular error messages are not covered in this
section. Record the message on a copy of the Diagnostics Checklist found in
"Getting Help." Also see "Getting Help" for instructions on obtaining
technical assistance.
Diagnostic Lights
Should your computer fail to operate, lights on the front panel and back
panel of the computer provide diagnostic codes that can help you
troubleshoot a computer problem. The following sections describe the
meaning of the diagnostic codes.
