System messages
For information about the event and error messages generated by the system firmware and agents that monitor system components, go
to qrl.dell.com > Look Up > Error Code, type the error code, and then click Look it up.
Warning messages
A warning message alerts you to a possible problem and prompts you to respond before the system continues a task. For example, before
you format a hard drive, a message warns you that you may lose all data on the hard drive. Warning messages usually interrupt the task
and need you to respond by typing y (yes) or n (no).
NOTE:
Warning messages are generated by either the application or the operating system. For more information, see
the documentation that shipped with the operating system or application.
Diagnostic messages
The system diagnostic utility generates messages if there are errors detected when you run diagnostic tests on your system. For more
information about system diagnostics, see the For information about the event and error messages generated by the system firmware and
agents that monitor system components, go to qrl.dell.com > Look Up > Error Code, type the error code, and then click Look it up..
