high-pitch beeping noise that last 3-4 seconds??

Hi Terrence,

Please share the system model and operating system installed.

Have you made any recent hardware or software changes?

Are you able to boot computer to Windows?

Please elaborate the issue and try to observe the system to identify if you can locate the part/portion producing beeps/clicking noise. You may also run onboard diagnostic test on your computer. For detailed steps on it, you may refer to link: http://dell.to/OUGnqT 

Make a note of error code if any and share the findings. 

Hi Chinmay,

I have a Dell Inspiron 15R model N5110. My operating system is windows 7 Home Premium. I have not made any changes to my hardware or software. The laptop is about 4-5 months old.

My computer is able to boot up perfectly fine and everything seems to be working. However, randomly (meaning every few days) there is a random high pitch double beep followed by a click. It appears to have no effect on my laptop. I have noticed that the sound appears to be coming from the area of the fan, which is on the left side of this model. So, it is not coming from the speakers and appears to be independent of them because this sound has occurred out loud when I've had head phones plugged in as well.

Also, I'm not sure if this is a problem, but since I've had my laptop, every time I've run a Dell Diagnostics Hardware Scan the "Targeted Read Test" always fails saying  "Module Failed to start"

Also I ran the onboard diagnostic test on the page you recommended. All the tests passed.

Hi Terrence,

I believe you ran the tests from the Dell Support Center. If the onboard diagnostics have passed, the system hardware is fine. You may uninstall the Dell Support Center from the ‘Control Panel’ and then re-install ‘Dell Support Center’ from the link: http://dell.to/RS19Iy  Select your region and follow the prompts.

In reference to issues with system fan,  please ensure that the vents of the system are clean and allow free circulation of air inside the system. You may use a can of compressed air to clean the vents. Before you clean the air vents of system:

1. Turn off the System.
2. Unplug the AC Adapter.
3. Remove the Battery.

For more information on cleaning the vents, please visit the link: http://dell.to/SAep59 

If the issue still persists, you may update the BIOS to latest version. Before you update system BIOS, please ensure that the ac adapter is connected and the battery is charged 10% or above. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved. 

Link to download system BIOS: http://dell.to/VbHnJ3 

Another step, you may try is to check the CPU usage of computer. Please ensure you check it when system fan is making noise. To check CPU usage:

• Then click on CPU tab once and check for the application with the maximum CPU usage.

• Right click on that application (make a note of the process) and click ‘End process tree’.
• Check if the same issue occurs. 
   
  

Hi Chinmay,

Thanks for your help. Uninstalling and then reinstalling the dell support center did fix the issue with the failed test.

As for the BIOS, I have not tried updating them yet, but I will try and let you know how it goes.

In the mean time, I was able to record the sound as well as another sound. Is there anyway that I would be able to send them to you?

Hello! 

I have the exact same problem on a 9-10 month old Dell Inspiron N5110 laptop, with Intel Core i5 processor (2,4GH) and 6GB ram.

It works alright, but since I got it, it randomly makes this high-pitched noise (as mentioned above, the pitch sometimes changes), for 2-3 seconds, followed by a click.

The sound does not come from the speakers, but from inside the laptop, the top left area. Unfortunately it comes and goes too quickly for me to check CPU usage as suggested, or record it. 

I was on the phone with Dell tech service, we ran diagnostics (extended too) but found no problem. I later sent the laptop for a checkup, but again, they found nothing.

I just wanted to add my experience, seems to be a recurring problem! Hopefully there is a solution!

Thank you for any help!

Hi Terrence,

You may update the system BIOS and see if the issue persists. Please ensure that the ac adapter is connected and the battery is charged 10% or above. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved.

Hi Chinmay,

http://en.community.dell.com/cfs-file.ashx/__key/communityserver-discussions-components-files/3518/7801.beep-2.m4a

The first one is the beep I hear every few days. The 2nd one I've only heard once out of the whole time I've had my laptop. Also I ran the bios update, but there has been no change.

Hi Terrence,

There might be an issue with the application running at the backend which might cause this issue. You may perform a clean boot and check the start up programs and services. For more information on this, you can refer to link: http://bit.ly/Vi0QXe 

Please share the findings. 

I have a Dell Inspiron 15, 7000 series that is about three years old.  Had lots of problems initially getting it set up; but, has been a good computer since then.  With that said, a few months ago, I started getting this totally random high pitch beeping sound when it boots up.  It has only happened three or four times; but, it is a very loud and piercing sound that goes away after a few beeps.  Doesn't seem to affect the computer in any way since it starts up fine and functions as normal once it is up and running.. My operating system is Windows 8.1 Home Premium and prior to this last beeping episode, I did install an updated version of MS Office 365 a few days prior.

Other than causing an uproar in the house when the beeping goes off, it doesn't seem to cause any other problems.  To me the beeping sound is the exact same as the sound that comes from a commercial truck or piece of heavy equipment when it starts to back up and in my opinion, it is just as loud.

Does anyone have a clue as to what this is or why it is happening?

Thanks

Please listen carefully to the series of beeps and report exact number of beeps. For example:If the beeps are in three then it's an issue / or problem with the motherboard or chipset. If the beeps are in four then it's an issue with Ram / Memory..
