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.

If the message persists, reinstall your operating

system. See the documentation that came with your

operating system.
