Reasons For Hp All-In-One Beep Codes 3 Long And 4 Short

HP All-In-Ones are great computers. But sometimes, they give you problems. One of those problems is the BIOS.

The HP 3 long beep indicates an issue with the BIOS settings. The 4 short beeping means that the flash­ing has failed, i.e., it was unable to complete.

The BIOS is the basic software that controls how your computer works. You might think that the BIOS is pretty simple, but it has a lot of complex settings. Sometimes, those settings cause problems.

Listen carefully to those beeping noises coming from your HP all-in-one without thinking too hard about them. You’ll usually find that there’s a regular pattern to them, and they are meant to tell you that there’s some sort of problem with your computer.

When Do You Hear Beep Codes?

These beeping codes are given out when there’s a problem with your computer. They’re indicative of problems with the BIOS, which is the part of the motherboard that controls how your computer boots up.

So, whenever you hear those beeping codes during the startup process, it means that there’s a problem with the BIOS.

This is why you should pay close attention to any beeping sounds that occur during the startup process. If you notice anything unusual, it might mean that your computer needs to be repaired.


What Causes The 3 Long And 4 Short Beep Codes?

The 3 long beeps and 4 short beeps are made up of two different types of beeps. Both of those beeps have specific meanings.

The 3 long beep indicates a particular problem, and the 4 short beeps mean something else entirely.

According to the HP Support Document about beeps with error codes, the 4 short beeps mean “Flashing Failed”. And according to a different website, the 3 long beeps indicate that the flashing is “unable to start”.

That might seem like a bit of gibbered, so let’s break down what it means.

So if you hear the 3 long beeps, it probably means that there was a problem with the flashing process.

But if you hear the 4 short beeps, it probably doesn’t mean anything bad.

Instead, it means that the flashing process started successfully, but then stopped working due to a software or hardware glitch.

1. External Devices and Hardware

This issue is usually caused by external devices like printers, scanners, mice, keyboards, etc. You should try checking if any of those devices are malfunctioning before trying to fix the problem yourself.

Another reason why you might experience this issue is if there is a hardware failure in your computer system. Try replacing the motherboard, CPU fan, power supply unit, hard drive, RAM, graphics card, etc.

Finally, the issue can also occur if there is a software problem in Windows operating system. Try updating the drivers for your motherboard, CPU, GPU, sound card, etc.

2. BIOS Image

There are two reasons why your computer might be beeping. One reason is that your motherboard or CPU may be defective. Another reason is that your BIOS image may be damaged.

Your motherboard or CPU is the main component inside your computer that controls how your computer works. If your motherboard or CPU is defective, then it won’t work properly. You’ll hear a constant beep noise whenever your computer starts up.

This problem usually happens when you install Windows 10 or any other operating system. But sometimes, it can happen after installing a driver update.

To find out whether your motherboard or CPU is faulty, try booting your computer using a Live CD/DVD. If your computer boots fine, then you know that your motherboard or CPU isn’t faulty.

Another solution is to download a copy of your BIOS image file and save it somewhere else. Then, replace the corrupted version with the saved one.

If you still experience problems, then you should contact a technician.

3. CMOS battery

A CMOS battery is a small battery that helps keep your computer running even when the power supply is turned off. It’s located inside your motherboard and powers the system BIOS.

So any issue with this battery failure can lead to problems with your computer. You might experience error from the category of error like “No bootable disk”, “Invalid signature” or “Missing operating system”.

To fix these issues, you should replace the CMOS battery. But before doing that, you should know how to identify whether your CMOS battery needs replacing. These are some tips on how to find out whether your BIOS battery is faulty.

Solutions To The 3 Long And 4 Short Beep Code Error

We’ll take a closer look at each solution separately with its cause identified.

1. Remove Any External Devices And Restart The Computer

If your computer keeps beeping when you plug in external devices, then there’s probably something wrong with those devices. You should try removing them and resetting your computer before continuing.

To remove external devices, turn off your computer. Then unplug all cables from your computer except for the power cord. Next, disconnect the power supply cable from the wall outlet. Finally, open the case of your computer and pull out the hard disk drive. After doing this, close the case and turn on your computer again.

Once you’ve done all of this, you should be able to start using your computer without any problems.

2. Troubleshooting Bios Image Issues

HP offers a free download of its BIOS update utility called “Update Manager”. This utility helps you to easily install the latest version of the BIOS.

Then select the Hardware tab and scroll down until you find the name of the motherboard. Click on the Properties button next to it. Now select the Updates tab and click on Download updates now.

After clicking on the Download updates now option, you will be directed to the HP Support site where you can download the latest version of the bios. After downloading the file, run the setup program and follow the prompts to finish installing the updated BIOS.

3. Fix The CMOS Battery

CMOS stands for Central Monitoring System. It’s a small chip inside your computer that monitors various aspects of your PC. One of those aspects is whether or not your power supply is providing enough electricity to keep your system running smoothly.

If your CMOS battery isn’t working properly, then you might experience random beeps coming from your computer. You can fix this issue by replacing the CMOS battery.

To find out if your CMOS battery needs changing, simply open up your computer and check its voltage level. If it reads below 3 volts, then replace the battery.
