Beep code

Description

1 short

RAM refresh failure, RAM on MB refresh circuitry failure, replace the memory bar.

2 short

Parity error, the first 64KB memory chip encounters parity failure. In CMOS settings, set memory ECC check to "DISABLED" and the problem is resolved. However, it is better to replace the memory.

3 short

Basic 64KB memory failure. Memory chip check fails and replace memory.

4 short

Clock error, timer on the system board does not work.

5 short

CPU failure, CPU on the system board encounters failure.

6 Short

A20 gate failure, keyboard controller contains A20 gate switch failure.

7 short

CPU exception interrupt error, CPU on MB generates an exception interrupt and cannot switch to protected mode.

8 short

Display memory error, no display on graphics or display memory error, change graphics or video memory.

9 short

ROM check failure, ROM check value is not identical with the one recorded in BIOS.

10 short

CMOS register read-write error, SHUTDOWN register in CMOS RAM failure.

11 short

CACHEerror-the outer CHCHE damage, indicates that external CACHE failure.

1 long -3 short

Memory error, memory corruption, replace the memory.

1 long -8 short

Display test error, data cable of monitor is not securely plugged in or the graphics is not properly attached.

Beep code

Description

1 short

Normal system bootup

2 short

Common error, set CMOS parameters and re-set the improper options

1 long -2 short

RAM or MB error, replace RAM or MB

1 long-2 short

Monitor or graphics error

1 long-3 short

Keyboard controller error, check MB

1 long-9 short

MB FLASH ROM or EPROM error，BIOS corruption, replace FLASH ROM

Continuously long beeps:

Memory bar is not plugged in or damaged. Re-plug or replace memory bar

Beeps continuously

Connect correctly and check all the plugs of power supply, monitor and graphics and make sure they are securely connected

Repeated short beeps

Power issue
