System Messages POST Beep Codes
Overview
Your system can provide you with diagnostic, error, and status information in the form of messages that
appear on the monitor screen, or beep codes that sound through the system speaker. This section
documents the diagnostic and beep codes and system messages generated by the system basic
input/output system (BIOS)
.
If a faulty system does not emit beep codes or display system error messages to indicate a failure, you
should run the appropriate tests in the Dell Diagnostics to help isolate the source of the problem. See
"Running the Dell Diagnostics" in the system Installation and Troubleshooting Guide.
Several different types of messages can indicate when the system is not functioning properly:
System messages
Diagnostics messages
Alert messages
POST beep codes
System Messages
System messages during the system's power-on self-test (POST) alert you to a possible operating system
problem or to a conflict between the software and hardware. Table 1
lists the system error messages that
can occur and the probable cause for each message.
NOTE: If you receive a system message that is not listed in Table 1, check the documentation for the
application program that is running when the message appears and/or the operating system
documentation for an explanation of the message and recommended action.
