System Beep Codes

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

A chip on the system board might

be malfunctioning.

The keyboard controller may be

malfunctioning, or one or more

RIMMs may be loose.

Power-on self-test (POST) has

queried the enhanced integrated

drive electronics (EIDE) drive for

status information. The drive has

returned a parameter from the call

that indicates it has detected

possible error conditions for its

operating specifications.

At system start-up, the BIOS

detected that one or both of the

thermal probes in the computer are

not operating.

At system start-up, the BIOS

detected that one or both

microprocessors are overheated.

After displaying this message, the

BIOS halts the processes and turns

off the system.

The operating system cannot write

Once your computer finishes booting,

immediately back up your data and

replace your hard-disk drive. Restore the

data to the replaced drive.

If a replacement drive is not immediately

available and the drive is not the only

bootable drive, enter

change the appropriate drive setting to

None. Remove the drive from the system.

This should be done only after you have

backed up the data.

You can continue to use the system, but

be aware that the temperature probe(s)

are disabled and if the processor

overheats, the Thermal Shutdown service

will not shut down the system.

NOTE: The Intel® Pentium® III

microprocessor has a built-in

thermocouple that halts microprocessor

operation if the microprocessor exceeds

its rated temperature.

To correct the problem, you must replace

your system board. For technical

assistance, see
