System Beep Codes
When errors occur during a boot routine that cannot be reported on the
monitor, your computer may emit a beep code that identifies 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 and look it up in the following table. If you are unable to resolve
the problem by looking up the meaning of the beep code, use the Dell
Diagnostics to identify a more serious cause. If you are still unable to resolve
the problem, contact Dell for technical assistance.
If the system loses power and beeps constantly when you turn it back on,
the BIOS is probably corrupted. See "
BIOS Recovery Utility " for
information on restoring the BIOS.
