Warning Messages - Dell OptiPlex GX100 User Manual

When errors occur during a boot routine that cannot be reported on the monitor, your computer may emit a series of beeps that identify the
problem. The beep code is a pattern of sounds: for example, one beep, followed by a second beep, and then a burst of three beeps (code 1-1-3)
means that the computer was unable to read the data in nonvolatile random-access memory (NVRAM). This information is invaluable to the Dell
support staff if you need to call for technical assistance.
When a beep code is emitted, write it down on a copy of the Diagnostics Checklist found in
unable to resolve the problem by looking up the meaning of the beep code, use the

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
