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
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).

Dell Diagnostics
, an error message may result. These particular error messages are not covered in this

Diagnostics Checklist

Getting Help
