Troubleshooting Your Computer
I
f your Dell computer is not working as expected, this
chapter provides both initial checks for solving basic
computer problems and detailed troubleshooting proce-
dures. It lists system messages and beep codes, their
possible causes, and actions you can take to resolve any
problems indicated by a message or code. This chapter
also offers some general guidelines for analyzing soft-
ware problems.
NOTE: When you see the question “Is the problem
resolved?” in a troubleshooting procedure, repeat the
operation that caused the problem to see if the problem
still occurs.

acking Up Your Files
You can lose data when a computer failure occurs. If your
computer is behaving erratically, back up your files
immediately. See your operating system documentation
for instructions on backing up files.

option in the System Setup program is set to OFF . Any
system beep codes sound at high volume, even if the
SPEAKER VOLUME option is set to OFF .

settings as explained in Chapter 2, “Customizing
System Features.”

incorrect. You have fixed the problem.
