Some time you notice a beep sound or two when you switch on your computer,it sound so embarassing because with the beeps,your computer will no boot.The underlisted beep sounds are there for you to solve your problems.
One beep:
One beep from a Phoenix based BIOS is actually an all systems clear notification. It’s an indication that the Power On Self Test is complete. There is no troubleshooting necessary.
One long beep, two short beeps:
One long beep followed by two short beeps indicates that there has been a checksum error. This means that there is some kind of motherboard issue. Replacing the motherboard should fix this problem.
One-two-two-three beep code pattern:
A1-2-2-3 beep code pattern means that there has been a BIOS ROM checksum error. Literally this would indicate an issue with the BIOS chip on the motherboard. Replacing the motherboard should fix this problem.
One-three-one-one beep code pattern:
A 1-3-1-1 beep code pattern on a Phoenix BIOS system means that there has been an issue while testing the DRAM refresh. This could be a problem with the system memory an expansion card or the motherboard.
One-three-one-three beep code pattern:
A 1-3-1-3 beep code pattern means that the 8742 keyboard controller test has failed. This usually means that there is a problem with the currently connected keyboard but it could also indicate a motherboard issue.
One-three-four-one beep code pattern:
A 1-3-4-1 beep code pattern on a Phoenix BIOS system means that there is some kind of issue with the RAM. Replacing the system memory usually fixes this problem.
One-three-four-three beep code pattern:
A 1-3-4-3 beep code pattern indicates some kind of issue with the memory. Replacing the RAM is the usual recommendation for solving this problem.
One-four-one-one beep code pattern:
A 1-4-1-1 beep code pattern on a Phoenix BIOS system means that there is an issue with the system memory. Replacing the RAM usually fixes this problem.
Two-one-two-three beep code pattern:
A 2-1-2-3 beep code pattern means that there has been a BIOS ROM error, meaning an issue with the BIOS chip on the motherboard. This Phoenix BIOS issue is usually corrected by replacing the motherboard.
Two-two-three-one beep code pattern:
A 2-2-3-1 beep code pattern on a Phoenix BIOS system means that there has been an issue while testing hardware related to IRQs. This could be a hardware or misconfiguration problem with an expansion card or some kind of motherboard failure.
What Does the Long Continuous Beep Sound Mean For Your Computer?
The type of beep your computer makes when starting up is meant to explain your computer’s status. One long, continuous beep generally means that there is a hardware problem – often memory related – that can prevent your computer from starting up at all.
If you can’t start your computer properly, you’ll need to take a look at the physical hardware inside your machine. In a best-case scenario, the computer can reset and return to normal functions. In a worst-case scenario, your computer is experiencing a major hardware malfunction that will require repair or replacement.
Try a Reboot First
Before tearing the computer apart to inspect the hardware, try a simple reboot. If you can access the menu and run a normal restart, go ahead and execute the process. If the computer is no functional while making the noise, press and hold the power button until it shuts down.
After forcing a shutdown, remove your power cord and the battery, and then wait for a full two minutes. Return the power and test the computer. If the noise persists, you have a potentially serious problem to address.
If the computer is beeping on startup, without any hesitation, the issue is most likely a hardware and memory problem.
Check the Battery
As a last ditch effort, always check the battery level or make sure that your computer is securely connected to a power source. Press all the plugs to snug everything up if needed. A loose power connection can drain the battery and many computer making beeping noises are only a warning that power is lost and a shutdown is looming.
If the power is solid and the battery is charged up, move on to more intensive troubleshooting processes. With any luck, the problem is resolved by snugging up your power cord.
Bad Memory Sticks
Although a long beep can mean you have hardware issues, this doesn’t necessarily mean that your hardware has gone bad. It could simply mean that it is loose or not seated correctly. Remove and replace your computer’s memory securely in their slots to try to fix the problem.
If this doesn’t work, and your computer has more than one memory stick, try inserting only one stick at a time; it could be that one stick has failed, while the other is fine.
Troubleshoot Your Chip
Your computer’s motherboard has a BIOS chip installed for the memory and processing. You must remove the protective panel to actually view the chip and determine the manufacturer. Turn off the power and make sure your computer is shut down before pulling the protective panels to access the motherboard.
Write down the company name and perform a quick search to access the troubleshooting codes. Each company uses different computer beep codes to determine specific problems. Look for the continuous beep in the BIOS chip manufacturer troubleshooting guide to determine the issue. Typically, the beeps happen in a coded sequence. When you hear a continuous beep, it is possible that there exists an overheating CPU or another major issue.
After determining the problem, you can attempt to fix the computer yourself or you can take it to a professional repair service.
