Beep Code Manual, Better Than Gold Techies, American Megatrends Int. & Phoenix
(I'm IT, I use these codes to trouble shoot hardware issues at my job. Enjoy) cold.gif
BIOS Beep Codes
When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected. Because there are many brands of BIOS, there are no standard beep codes for every BIOS.
The two most-used brands are AMI (American Megatrends International) and Phoenix.
Below are listed the beep codes for AMI systems, and here are the beep codes for Phoenix systems.

AMI Beep Codes
Beep Code Meaning 1 beep DRAM refresh failure. There is a problem in the system memory or the motherboard. 2 beeps Memory parity error. The parity circuit is not working properly. 3 beeps Base 64K RAM failure. There is a problem with the first 64K of system memory. 4 beeps System timer not operational. There is problem with the timer(s) that control functions on the motherboard. 5 beeps Processor failure. The system CPU has failed. 6 beeps Gate A20/keyboard controller failure. The keyboard IC controller has failed, preventing gate A20 from switching the processor to protect mode. 7 beeps Virtual mode exception error. 8 beeps Video memory error. The BIOS cannot write to the frame buffer memory on the video card. 9 beeps ROM checksum error. The BIOS ROM chip on the motherboard is likely faulty. 10 beeps CMOS checksum error. Something on the motherboard is causing an error when trying to interact with the CMOS. 11 beeps Bad cache memory. An error in the level 2 cache memory. 1 long beep, 2 short Failure in the video system. 1 long beep, 3 short A failure has been detected in memory above 64K. 1 long beep, 8 short Display test failure. Continuous beeping A problem with the memory or video. BIOS Beep Codes

Phoenix Beep Codes
Phoenix uses sequences of beeps to indicate problems. The "-" between each number below indicates a pause between each beep sequence. For example, 1-2-3 indicates one beep, followed by a pause and two beeps, followed by a pause and three beeps. Phoenix version before 4.x use 3-beep codes, while Phoenix versions starting with 4.x use 4-beep codes.

SOURCE: operating systems doesn't boot (BIOS beep codes)?

Do you have video going to your monitor? If not the beeps mean you have a bad memory stick in there. If you have video the beeps are the bios telling you that its not set right. More than likely you have it set to run too fast. Go into your bios find where the processor speed is located and choose a lower freq. rate. Its probably set too high for the memory you have.

SOURCE: acerpower f2 bios beep codes

The beeps are post during post the very first work is done by the ram all the memory in the ram is first transferred to the hard disk and remains active until turned off.

make sure that your RAM modules and Cmos battery sockets are clean and dust free and the ram modules are securely seated in some motherboards cmos batteries are soldered in


Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection


and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty or just replace them they could be faulty ?

one bad lead will end with a computer error a computer needs its connections continue its cycle and have an end to function properly


even something as small as an electrical extension or a faulty fan lead can cause this problem computer needs all of the data and electrical current to travel through every device and to have an end to be able work properly


hope this helps

Compaq d290mt beeps continously....on startup



Beep code are tied to the BIOS. You might have to open up the computer and look for the information on the motherboard. http://www.wikihow.com/Identify-the-Motherboard.

If your PC was operational, you could use Speccy (freeware) or Belarc Advisor to learn what the BIOS is.

Although I can point you to some beep code sites, you still need to know what BIOS you have. You might track that at the motherboard manufacturer's website.

Here are some beep codes but until you know the BIOS, you are shooting in the dark. Some will guess "bad ram", others will say "bad power supply." But these are guesses unless you know what the beep code actually means.

Short beep long beep


1 long, 1 short beepSystem board problem When your computer boots up, the Basic Input-Output System (BIOS) performs an all-systems Power On Self-Test (POST).
The POST tests your computer's most important components, including the motherboard itself, the system's memory and the video card.
If the computer deviates from its standard beep, it may indicate a very serious problem with your computer, or it may simply indicate that you need to replace a system fan or a memory stick. BIOS beep codes vary according to manufacturer.

Start your computer.
Pay attention to the number of beeps and the length of the beeps.
There are short and long beeps.
Write down your observations.
Write down the BIOS type if this information is on your screen.
Consult your computer documentation if you don't know what type of motherboard you have.
Visit your computer manufacturer's support website for your computer model if you purchased a pre-built machine.


Look up your BIOS manufacturer (AMI, Award and Phoenix, for example) at a BIOS beep code website such as 5StarSupport, PC Hell or PC Guide (see Below).
Match the your computer's beep code with the beep code listing for your BIOS manufacturer.

When rebooted computer beeps 3 times and will not turn on


Is it a long beep or a short beep? Beep codes are used by the BIOS during the POST to report certain initial system errors.

If you're hearing beep codes after you turn your computer on, it typically means that the system has encountered some kind of problem before it was able to display any kind of error information on the monitor.

Follow the steps below to determine what system problem the beep code is representing.
Difficulty: AverageTime Required: Anywhere from 10 minutes to a few hours depending on the cause of the beep code

Here's How:

  1. Power on the computer or restart it if it's already on.

  2. Listen very carefully to the beep codes that sound when the computer begins to boot.

    Restart your computer if you need to hear the beeping again. You're not likely to make whatever problem you have worse by restarting a few times.

  3. Write down, in whatever way makes sense to you, how the beeps sound.

    Important: Pay close attention to the number of beeps, if the beeps are long or short and if the beeping repeats or not. There is a big difference between a "beep-beep-beep" beep code and a "beep-beep" beep code.

    This is all important information that will help determine what issue the beep codes are representing.

  4. What steps you take to solve a particular beep code will differ depending on the BIOS manufacturer.

    Choose the correct beep code troubleshooting guide below based on your motherboard'sBIOS manufacturer:

    Tip: Not sure what brand of BIOS is on your motherboard? See this How To Determine Your Motherboard BIOS Manufacturer guide for some helpful advice.

Tips:

  1. Still can't figure out what the beep codes mean? Let a community of computer support enthusiasts help out! Post the details of your problem in the PC Support Forum.

The PC does not start.Only it beeps and a red light blinks,also fen is not working.


here are some of the basic codes, depending on which BIOS you have...

Also you do not indicate which fan? I would guess you mean the main Power Supply (PS)? In which case it could just be you need to replace the PS.

Here is a link to some other codes as well...

  • 1 Beep - Memory Refresh Failure (check memory)
  • 2 Beeps - Memory Parity Error in first 64KB block (check memory)
  • 3 Beeps - Memory Read/Write Error in first 64KB block (check memory)
  • 4 Beeps - Motherboard timer not functioning (possible motherboard replacement)
  • 5 Beeps - Processor Error (may need replacement Processor)
  • 6 Beeps - Gate A20/keyboard controller failure (possible motherboard replacement)
  • 7 Beeps - Processor Exception Interrupt Error (may need replacement Processor)
  • 8 Beeps - Display Memory Read/Write Failure (reseat or replace video card)
  • 9 Beeps - ROM checksum Error (replace BIOS chip or motherboard)
  • 10 Beeps - CMOS shutdown Read/Write error (possible motherboard replacement)
  • 11 Beeps - Bad Cache Memory - test failed (replace cache memory)

Phoenix BIOS ERROR BEEP CODES
Phoenix BIOS beep codes are a series of beeps separated by a pause, for example:
beep --- beep beep --- beep --- beep beep would be 1-2-1-2
  • 1-1-4-1 - Cache Error (level 2)
  • 1-2-2-3 - BIOS ROM Checksum
  • 1-3-1-1 - DRAM Refresh Test
  • 1-3-1-3 - Keyboard controller test
  • 1-3-4-1 - RAM Failure on address line xxxx (check memory)
  • 1-3-4-3 - RAM Failure on data bits xxxx of low byte of memory bus
  • 1-4-1-1 - RAM Failure on data bits xxxx of high byte of memory bus
  • 2-1-2-3 - ROM copyright notice
  • 2-2-3-1 - Test for unexpected interrupts
I hope this helps.

Computer beeps 10 times on startup and switches off


The beep codes should indicate hardware detection or mis match issues. Check if the RAM is loose, or there is a problem with the display connectivity, hardware or the hard disk attached. Different Bios have different beep codes for identifying the issues. We would clearly state the beep indication if we could know the Bios model and version which you can see on the Bios chip. Good luck.

My E-Machine T6544 will not boot up - monitor reads no signal, but fan and hard drive seem to be running on the tower


Do you hear any beep codes?

Your BIOS manufacturer's site will explain in full the beep codes you're experiencing. The beeps you are explaining is your system failing the POST (power on checks), it emits a series of beeps to tell you the precise nature of the problem. Beep codes are BIOS-specific. The following BIOS sites should help you. You must however first, identify which BIOS you've got.
Award � http://www.phoenix.com/pcuser/BIOS/award_error_codes.htm
Phoenix � http://www.phoenix.com/pcuser/PDF-Files/bios-postcode.pdf
AMI � http://www.ami.com/support/ For all other bioses try http://www.abios.com

At POST I get 2 short beeps


it depends on the bios chip maker Here's some other beep codes:

for Award and Phoenix BIOS:

1 short beep: Normal
2 short beeps: CMOS error
1 long and 1 short beep: DRAM error
1 long and 2 short beeps: Video card error
1 long and 3 short beeps: Keyboard error
1 long and 9 short beeps: ROM error
Long continuous beeps: DRAM not installed correctly
Short continuous beeps: Bad power supply


AMI BIOS:

1 short beep: DRAM flash error
2 short beeps: DRAM ECC check error
3 short beeps: DRAM detect error
5 short beeps: CPU error
6 short beeps: Keyboard error
8 short beeps: Video card error
9 short beeps: ROM error
1 long and 3 short beeps: Bad DRAM
1 long and 8 short beeps: Video card error


Invoking Beep Codes

.

If the computer is actually functioning and the computer beeps continuously, then there is a problem with a voltage on the power supply being incorrect or the CPU overheating. IMMEDIATELY go into the BIOS and check CPU temperature, fan speed and voltages

**********************************************
BIOS Beep Codes

Annoying isn't it? You have built your computer you switch it on and then nothing happens except a few beeps from the PC speaker. Frustration sets in as you try to figure out what is wrong with it. If you didn't already know the computer has already told you the problem. It can't speak of course but it can direct you to the problem. Its all in the beeps. The BIOS can recognise when the problem occurs and sends a signal out to send a certain amount of beeps through the speaker. These beeps then tell you the location of the problem.

Unfortunately not all the BIOS' use the same codes as each other. Two of the main BIOS manufactures AMI and Award (now Phoenix) have different codes for there errors.

AMI BIOS

# of Beeps Error Description
1 Refresh Failure The memory refresh Circuitry is faulty
2 Parity Error Parity error in the Base (1st 64K) of memory
3 64K Base Memory Error Memory error in the base memory (1st 64K)
4 Timer Not Operational Timer 1 is not functioning (also caused by error in base memory)
5 Processor Error CPU error
6 8042 Gate A20 Failure Unable to switch to protected mode
7 Processor Exception Interrupt error The CPU on the CPU card generated an interrupt error
8 Display Memory Read/Write Error Video adapter is missing, incorrectly seated or has faulty memory
9 ROM checksum error The ROM checksum does not match that of the BIOS
10 Coms Shutdown Register Read/Write The shutdown register for coms RAM has failed
11 Cache Memory Bad The cache memory test has failed. Cache memory will be disabled. *** DO NOT enable it ***


With the first 3 beep codes, its well worth re-seating the memory just to make sure that it's in correctly. 8 Beeps is probably the most common in my experience. Can be caused by a badly seated Graphics card. If you have re-seated it then check with another Graphics card in the board.

Always check for loose components before sending the board back as this is the main cause of errors on the POST.



Award BIOS

Award states that they now only use one beep from there BIOS. This beep is one long beep and then two short beeps. This indicates a graphics card problem. Any other beeps should be treated as a RAM problem first and then the board sent in to be inspected.

The reason that the Award BIOS only uses the beep code for display problems is that it tries to display the error on-screen if at all possible. If the BIOS cannot initiate the display adapter then this causes the BIOS to make the beep code for a display error, which must be corrected before any other errors can be determined. Memory Test fails and hard disk failures etc will all be displayed on screen

IBM BIOS

The IBM BIOS works with Short and Long beeps as well as the Award BIOS. However the IBM one does still have codes to work from.

Beep Code Error
1 Short Beep Normal POST, System booted OK
2 Short Beeps POST Error - Code on Display
No Beep Power supply or Motherboard error
Continuous Beep Power supply or Motherboard error
Repeating short beeps Power supply or Motherboard error
1 short, 1 long beep System board error
1 long, 2 short beeps Display adapter error (MDA/CGA)
1 long, 3 short beeps Display adapter error (EGA/VGA)
3 long beeps 3270 keyboard card
Phoenix BIOS
The Phoenix BIOS works on a slightly more complicated manor than the others. It does display an error code for you and produce a series of beeps. This BIOS produces its beeps according to the hexadecimal code the error produces. The Phoenix BIOS has many different codes for its possible errors and so many different beep codes. Rather than list the entire section here, I have provided a link to the official PDF file containing the codes and how they are derived.

Phoenix BIOS Post Codes

System board errors should be looked at by a specialist, Again always try to re-seat components to ensure they are in correctly. If necessary take all components out except for the RAM CPU and graphics card, then try the system. Re-seating components is the number one fix for getting past the POST screen. One badly seated components can cause the entire system not to function. so pick out your bios and follow the steps above to diagnose .hope this helps
