System Setup Options
You can easily correct certain system problems by verifying the settings for system setup
options. When you boot your computer, it compares the system configuration information with
the current hardware configuration. If your computer's hardware configuration doesn't match
the information recorded by the system setup options, an error message may appear on your
display.
To fix this problem, correct the appropriate system setup options and reboot your computer.
See Using the System Setup Program, for detailed information.
If, after checking the system setup options, you have not resolved the problem, see Running
the Dell Diagnostics.
Messages and Codes
Your application programs, operating system, and the computer itself are capable of identifying
problems and alerting you to them. When this occurs, a message may appear on the
computer's display or on an external monitor (if one is attached), or a flash code may be
emitted.
If an error message appears on the display or external monitor, make a note of the message.
See Table 3-2 for an explanation of the message and suggestions for correcting any errors.
The messages are listed alphabetically.
