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 "

Getting Help

," and then look it up in Table 2. 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, see "

Getting Help

" for instructions on obtaining technical assistance.

WARNING: Dell's Disk Monitoring System
has detected that drive [0/1] on the
[primary/secondary] EIDE controller is
operating outside of normal
specifications. It is advisable to
immediately back up your data and replace
your hard-disk drive by calling your
support desk or Dell Computer
Corporation.

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.

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

System Setup

and

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.

Warning - Thermal probes failed.

At system start-up, the BIOS
detected that one or both of the
thermal probes in the computer are
not operating.

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 "

Getting Help

Warning - Temperature is too high.

At system start-up, the BIOS
