Meaning of Beeps on Computers and Solutions

Do you know what the function of the small speakers installed on the mainboard of your computer is? Beep sound, that's the function of the small speaker on the mainboard of our pc. This beep sound has a meaning, you know, not without the intention of the computer company giving a speaker that is only the size of this mentos candy.

Well, on this occasion I will explain what types of beeps sound, what do they mean, and how to overcome them?

Make sure to read until the end, yes, so that the knowledge will be more joss. It is also important to know the meaning of the beep on your computer.

When the computer is turned on for the first time, the computer will pass the POST (Power On Self Test), what is POST? That is the process where the computer checks that the hardware installed in it is working normally or there is a problem. This POST is part of the BIOS.

Computer Beeps

One beep means the system has passed the test and the BIOS states that the CPU, memory, and video are functioning properly. for other beep codes of course have their own meaning according to the type of BIOS and the brand of the mainboard.

In general, rapid and repeated beeps indicate that there is a memory error. The following are some BIOS beep codes from several BIOS manufacturers. Beep codes differ from company to company that makes them.

Beep Codes from Standard Original IBM POST error codes.

  • 1 short beep: Normal POST and computer system OK
  • 2 short beeps: POST Error – will display an error code on the computer screen, check the computer correctly
  • No beeps: there is a problem with the power supply or system board, monitor/memory is not installed, check PSU make sure the cable is plugged in properly
  • Repeated beeps: PSU problem, system board or keyboard problem, check cable properly
  • repeated short beeps: Power supply or system board problem
  • 1 long beep 1 short beep: System board problem
  • 1 long beep 2 short beeps: Problem with the display adapter or VGA Card part 
  • 1 long beep 3 short beeps: The problem with the Enhanced Graphics Adapter (EGA) is still in the VGA Card section
  • 3 long beeps: Keyboard problem, make sure it is installed properly

The following is a description code from the BIOS for the BIOS POST type

  • 7300-7399: 3.5″ Disc drive
  • 8900-8999: Adapter on Midi
  • 11200-11299: SCSI Adapter
  • 21000-21099: SCSI F Disk and Controller
  • 21500-21599: SCSI CD-ROM System

Beep Code from AMI BIOS

  • 1 short beep: All normal. If there is no display on the monitor, reboot again.
  • 2 short beeps: Memory problem
  • 3 short beeps: Almost the same as 2 short beeps
  • 4 short beeps: Almost the same as 2 short beeps can also system timer fail
  • 5 short beeps: Motherboard problem, try resetting memory and rebooting
  • 6 short beeps: The chip on the motherboard that controls the keyboard is not working. Use another keyboard
  • 7 short beeps: Processor is faulty, replace the processor with a new one
  • 8 short beeps: Video card not working
  • 9 short beeps: BIOS corrupted, re-flash BIOS
  • 10 short beeps: CMOS is faulty, all CMOS-related chips must be replaced/replace the new mainboard
  • 11 short beeps: A problem with the cache memory on the mainboard. Replace the memory chip or replace the new mainboard
  • 1 long beep 3 short beeps: Memory failure, occurred after installing additional memory
  • 1 long beep 8 short beeps: Display test failed, reset the video card

Beep Code from Phoenix BIOS

In the Phoenix BIOS, the beep is distinguished by the sound pause, not using the length or the shortness of the sound. For example, beep-beep beep-beep-beep means 1-3-1

  • 1-1-3: The computer does not read the configuration in the CMOS, the solution is to replace the mainboard
  • 1-1-4: Change BIOS
  • 1-2-1: Chip timer error, replace the new mainboard
  • 1-2-2: Mainboard is broken
  • 1-2-3: Mainboard is broken
  • 1-3-1: Mainboard is damaged, replace it with a new one
  • 1-3-3: Mainboard is damaged, replace it with a new one
  • 1-3-4: Mainboard is broken
  • 1-4-1: The mainboard is broken
  • 1-4-2: Memory is damaged, replace the memory
  • 2-_-_: Some memory is damaged
  • 3-1-_: one of the chips on the mainboard is damaged, replace the new mainboard
  • 3-2-4: Keyboard error checking chip, replace the mainboard
  • 3-3-4: Video card not read, replace the video card
  • 3-4-_: Video card not working, replace the video card
  • 4-2-1: Mainboard chip error, replace the mainboard
  • 4-2-2: Check keyboard installation
  • 4-2-3: Same as 4-2-2
  • 4-2-4: one card error
  • 4-3-1: Change Mainboard
  • 4-3-2: Change Mainboard
  • 4-3-3: Change Mainboard
  • 4-3-4: Clock error, replace CMOS battery
  • 4-4-1: serial port is damaged, replace I/O card or replace the mainboard
  • 4-4-2: similar to 4-4-1, but crashes on the parallel port
  • 4-4-3: Match coprocessor error
  • Low 1-1-2: Mainboard error
  • Low 1-1-3: Check CMOS ram, check mainboard and CMOS battery

Beep Code from Award BIOS

  • 1 short beep: normal PC
  • 1 long beep: Memory check
  • 1 long beep, 2 short beeps: Error in DRAM
  • 1 long beep, 3 short beeps: Error in memory module or video memory
  • 1 long beep, 9 short beeps: BIOS faulty, replace the mainboard

That's the Meaning of the Beep on the Computer and the Complete Solution. Hopefully, it will add to our knowledge of how to deal with the beeps that appear when we use the computer
