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).

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 your Diagnostics Checklist. Also see "Getting Help" for instructions on obtaining technical assistance.

Diagnostic LEDs

Light-emitting diodes (LEDs) are located on the front panel and back panel of the chassis. These LEDs emit diagnostic codes that can help you

troubleshoot a system problem. The following sections describe the meaning of the diagnostic codes.

Front Panel LEDs

Table 3 lists the codes for the front panel diagnostic LEDs, probable causes, and suggested corrective actions.
