Your laptop can beep for many reasons, ranging from normal operational beeps to critical fault beeps. Discerning which is which can be a frustrating and difficult process, if you don’t know what to look for.

I’m Aaron, a lawyer turned technologist. I’ve parlayed my hobby into a career because I love solving technology problems. Let me help solve yours!

Let’s evaluate some of the reasons your laptop may be beeping and what you can do to fix it. 

Key Takeaways

  • Your laptop can beep because of various operating system events.
  • It could also beep because of easily fixable hardware issues, like stuck keys or cables with diminished functionality. 
  • If your laptop beeps once when it boots, that’s normal.
  • If your laptop beeps more than once when it boots or fails to boot after beeping, that’s not normal and means that you have hardware problems. 

Why Your Laptop is Beeping

There are a few reasons your laptop beeps. Some of them might happen when you’re in an operating system. Others might happen when the laptop is booting. The stage of your computer’s booting will help inform why its beeping and, in turn, how to fix it. Let’s start with when you’re computer’s already booted and…

In an Operating System

When you’re computer’s in an operating system, there can be a few reasons it beeps. One is to alert you about…

1. Accessibility Settings

Windows 7 and 10 provide audio notifications when you press key combinations, or keyboard shortcuts, enabling accessibility settings. When pressing those shortcuts, Windows provides an audio notification in the form of beeps that you’re trying to enable those shortcuts. 

The easiest way to stop that form of beeping is not to press those key combinations. They’re not widely needed in the course of normal computer use (hence why they were picked for accessibility options) so you should be able to avoid them very easily. 

Similarly, it could also be…

2. Multi-Key Press Notifications

Some computers provide the option to enable notifications when multiple keys are pressed at once. If you have this enabled, your computer will notify you of multiple key presses. This sounds like a series of beeps, if you’re pressing a lot of key combinations.

Consult your laptop’s manual to see if it has that functionality. If it does, your manual will tell you how to disable that. 

Another keyboard-related issue may be…

3. Stuck Keys

If your keyboard’s keys are stuck, then the computer will identify repeated key presses for as long as it’s stuck. Eventually, your computer may start beeping to let you know. You can fix this by checking your keyboard for stuck keys and trying to fix or unstick them. 

Another software-related issue is…

4. Frozen Operating System

Sometimes, when your operating system freezes, it will indicate that’s occurred by beeping when you press keys on the keyboard. 

You can fix that by restarting your computer–turning it off and then on again. While that’s unlikely to fix the root cause of why your computer froze, it will address the issues caused by that freezing. 

Alternatively, it could be…

5. Low Power

When your laptop’s running low on power and isn’t plugged in, it might beep to let you know that it’s about to shut down. The solution to this is simple: plug in the laptop. If you can’t, then save any unsaved work and shut the laptop down. 

Similarly, it could be…

6. Cable Problems or Inadequately Powered Peripherals

You may have a peripheral plugged into your computer, like a mouse, keyboard, or external hard drive. Those things plug into the computer with a cable, which is a housing for many strands of wire that transfer data and power. 

Some of those strands may fray or break, usually at the connector at either end, but sometimes in the length of the cable. If that happens, it could make a connection that intermittently disconnects. 

That connection, in turn, will register in your operating system as a connection and disconnection event every time the wire makes contact and disconnects. If your operating system makes a sound during a connection and disconnection, that might seem like intermittent beeping. 

Alternatively, you could have a device that’s inadequately powered by your computer’s ports. This happens sometimes with older portable external hard drives that need more power than provided by one USB port. If plugged into one USB port, it may register and then disconnect when the drive spindle powers, just to reconnect again seconds later. 

To fix this, check your cables. Also, if you have a device that was paired with a specific cable (e.g.: a USB Y-cable) make sure you replace it with a similar cable to avoid underpower situations. 

There may be other reasons your computer’s beeping when booted into an operating system, but they’re not very common. If you encounter one of those issues, you’ll want to seek help. You’ll also likely want to seek help if you hear…

Beeping when Your Laptop Boots

Your laptop will beep on boot. That’s a good thing. Beep codes are a tool that’s been employed for more than four decades to help end-users and technicians identify computer issues that prevent the computer from booting. 

Here’s a YouTube video highlighting what that sounds like and the troubleshooting process.

Your laptop may beep once on boot. That’s a good thing and typically means that it has passed its Power-On Self-Test, or POST, diagnostics and will boot into an operating system. If your laptop beeps more than once and doesn’t boot, then you have a hardware issue. 

Unfortunately, there’s no standard for computer beep codes. You’ll need to search for your computer’s model number to identify what the beep codes mean. Based on the results, you’ll need to address the underlying hardware issue the beep identifies so that your computer can boot. 


There are many reasons your laptop will beep. Some are good and easy to fix if they’re not. Others are more difficult and may include costly repairs.
