Beep codes

Whenever a recoverable error occurs during the power-on self-test (POST), the BIOS
displays an error message that describes the problem. The BIOS also sounds a beep code
(one long tone followed by two short tones) during POST if the video configuration fails
(a faulty video controller) or if an expansion card is not functioning correctly. One short
beep indicates the BIOS will boot the operating system. No error found.
A PCI expansion card (for example, a RAID controller) can also issue audible errors by itself,
usually consisting of one long tone followed by a series of short tones. For more
information on the beep codes issued, check the documentation for that device.
The following table shows POST error beep codes. Prior to system video initialization, BIOS
uses these codes to inform users of error conditions.
Beeps Description
1 Memory refresh timer error
2 Parity error in the first 64 KB of memory.
3 Base memory read/write test error
4 System board timer not operational.
5 The processor on the system board
generated an error.
6 The keyboard controller (8042) may be
defective. The BIOS cannot switch to
Protected mode.

Troubleshooting steps
Reseat the memory modules or replace with
modules you know are good.
Same as for 1 beep.
Same as for 1 beep.
Possible system board malfunction. To
eliminate the possibility of an add in-card
problem, remove all expansion cards.
If the beep code occurs even when all
■
expansion cards have been removed, the
system board is at fault.
If the beep code does not occur when the
■
expansion cards have been removed, one
of the cards is causing the problem. Install
the cards one at a time until the problem
happens again. When the beep code
returns, the most recent card you installed
is at fault.
Try a known good processor in the processor
socket.
Same as for 4 beeps.
Remove the keyboard to see if the error goes
away. If it does, try a known good keyboard.
Same as for 4 beeps.
