Beep Codes
Your computer may emit a series of beeps during start up. The series of beeps
is called a beep code and can be used to help identify a problem with your
computer.
If your computer emits a series of beeps during start-up:
1
Write down the beep code.
2
Run the Dell Diagnostics to identify the cause (see "Dell Diagnostics" on
page 41).
Another failure has
occurred.
• Ensure that all hard drive and
CD/DVD drive cables are properly
connected to the system board (see
"System Board Components" in your
User’s Guide
).
• If there is an error message on the
screen identifying a problem with a
device (such as the floppy drive or
hard drive), check the device to make
sure it is functioning properly.
• If the operating system is attempting
to boot from a device (such as the
floppy drive or CD/DVD drive), check
system setup (see "System Setup" in
your
User’s Guide
) to ensure the boot
sequence is correct for the devices
installed on your computer.
• If the problem persists, contact Dell
(see "Contacting Dell" in your
User’s
Guide
).
