- Pay attention! Depending on each device, the BIOS speaker settings may vary. Some devices have built-in speakers on the mainboard, while others connect to the Speaker jumper. Technicians assembling computers may forget to install the BIOS speaker, resulting in no sound on your computer. Therefore, check your device before performing computer troubleshooting via BIOS and CMOS beep sounds.
Troubleshoot computer errors using BIOS and CMOS beep sounds lookup table.
Describe computer errors through AMI BIOS and CMOS beep sounds.
- 1 short beep: When starting up the computer, a short beep indicates the initiation of the system, and the system has started with display tests showing parameters on the screen.
- 2 short beeps: This sound indicates that your RAM is not being recognized. Before troubleshooting, check your graphics card (if applicable). Remove both the RAM and graphics card for cleaning, then reseat each device to test. If it works well, check for any error messages on the screen. If none, your memory might have a parity error. Reseat the RAM and restart. If the issue persists, swap RAM slots.
- 3 short beeps: Essentially, this error is similar to the 2 short beeps notification.
- 4 short beeps: Similar to the 2 short beeps scenario, but it could also be due to a faulty motherboard clock. Access the BIOS to reset the date and time or replace the CMOS battery to verify this situation.
- 5 short beeps: Reseat the RAM. If the issue persists, you may need to replace the motherboard.
- 6 short beeps: The chip controlling the keyboard on the motherboard is malfunctioning. Initially, try reconnecting or using a different keyboard. If the issue persists, it's time to consider replacing the motherboard.
- 7 short beeps: The CPU is faulty and needs replacement. To be sure, remove the CPU, clean the pins and contacts, then reattach it for a reevaluation.
- 8 short beeps: The graphics card is not functioning. Reinsert the graphics card. If the beeping continues, the cause may be a damaged card or faulty memory chip on the card. Replace the graphics card.
- 9 short beeps: Your BIOS is corrupted. Replace it with a new BIOS.
- 10 short beeps: Your issue lies in the CMOS. It's best to consider replacing the motherboard.
- 11 short beeps: The buffer memory chip on the motherboard is damaged. Replace the motherboard.
- 1 long beep, 3 short beeps: RAM error. Try cleaning the RAM pins and slots, then reseat it in a different slot. If there's no improvement, consider replacing the RAM.
- 1 long beep, 8 short beeps: Video test failed. Reinsert the graphics card.
Description of computer errors through BIOS beeps, CMOS Phoenix.
1-1-3: Your computer is unable to read the configuration information stored in CMOS.
1-1-2: The mainboard is experiencing issues.
1-1-4: BIOS needs replacement.
1-2-1: The clock chip on the mainboard is damaged.
1-2-2: The motherboard is experiencing issues.
1-2-3: The motherboard is experiencing issues.
1-3-1: You need to replace the motherboard.
1-3-3: You need to replace the motherboard.
1-3-4: The motherboard is experiencing issues.
1-4-1: The motherboard is experiencing issues.
1-4-2: Check the RAM again.
2-_-_: If you hear a prolonged beep after 2 short beeps, it indicates an issue with your RAM.
3-1-_: One of the chips on the mainboard is damaged. It's likely you'll need to replace the mainboard.
3-2-4: The keyboard test chip is malfunctioning.
3-3-4: Your computer can't detect the graphics card. Try reinserting the graphics card or testing with onboard graphics (if available) or a different card.
3-4-_: Your graphics card is not functioning.
4-2-1: One chip on the mainboard is damaged.
4-2-2: Check if there are any issues with the keyboard. If not, the mainboard has a problem.
4-2-3: Check if there are any issues with the keyboard. If not, the mainboard has a problem.
4-2-4: One of the add-on cards plugged into the motherboard is damaged. Try removing each device to identify the cause.
4-3-1: Motherboard error.
4-3-2: Motherboard error.
4-3-3: Motherboard error.
4-3-4: The clock on the motherboard is malfunctioning. Try accessing the BIOS and resetting the date and time. If the clock remains nonfunctional, attempt replacing the CMOS battery.
4-4-1: Error related to the serial port. Attempt reconnecting this port to the motherboard. If unsuccessful, search for a jumper to disable this serial port.
4-4-2: Similar to the 4-4-1 error, but this time involving the parallel port.
4-4-3: The digital signal processor is encountering issues. If the problem is severe, it's advisable to replace the motherboard.
This article compiles a reference table for diagnosing computer errors through BIOS beeps and CMOS. Mytour hopes to help readers interpret issues based on simple startup sounds, allowing for effective troubleshooting. During the diagnostic process using BIOS beeps, accessing the BIOS for configuration adjustments may be necessary. Depending on your machine, BIOS entry methods vary, but you can also refer to previously shared shortcut keys for Boot Options and BIOS for various machine models.
CMOS battery provides power to the BIOS, preserving information when the computer is suddenly unplugged. Therefore, the CMOS battery plays a crucial role. If the CMOS battery is depleted, replacing it is essential. Learn how to choose and replace the CMOS battery correctly through Mytour's guide.
CMOS and BIOS are closely related. Often, the 'BIOS checksum Error' occurs when the CMOS fails to supply sufficient power. To identify the cause and resolve the BIOS checksum Error, follow the article on fixing BIOS checksum Error on Mytour.
