About Your System
LCD Status Messages
The system's control panel LCD provides status messages to signify when the
system is operating correctly or when the system needs attention.
The LCD lights blue to indicate a normal operating condition, and lights
amber to indicate an error condition. The LCD scrolls a message that
includes a status code followed by descriptive text. Table 1-6 lists the LCD
status messages that can occur and the probable cause for each message. The
LCD messages refer to events recorded in the System Event Log (SEL). For
information on the SEL and configuring system management settings, see
the systems management software documentation.
CAUTION:
Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered
by your warranty. Read and follow the safety instructions that came with the
product.
NOTE:
If your system fails to boot, press the System ID button for at least five
seconds until an error code appears on the LCD. Record the code, then see "Getting
Help" on page 167.
