Computer Makes High Pitched Noise When Plugged In

The natural response is to turn the brightness down using the monitor's controls. That's when the monitor can start to emit some high frequency tones, which are described most often as buzzing or whining. The noise usually gets worse the more the screen is dimmed. It can be piercing and annoying enough to overcome even relatively high ambient noise. Best Answer: It is one of four things. All of which should be checked. 1 your speakers may be picking up fan noise an exposed wire will do this check all of your connections. 2.If it is a high pitched wine as you described it then you may be losing a bearing in one of your hard drives which means it could. The high pitched noise may be due to your fans needing to be cleaned, try blowing air forwards and backwards through the fan. Another option is to shut your computer off and let it cool down. If noise continues you may need to take the computer apart to do more cleaning of the fans.

High Pitched Sound From Computer

FAQ & Answers

• Hi,

  The fans are normal, under heavy load they will spin.

  Regarding the sound, well it can be coil whining, but I cannot be sure, and unfortunately most manufacturers don't consider it as a manufacturing defect.

  In the two youtube videos you have explained what is coil whining and also an example. It can happen on the notebooks as well. If you strongly think that is coil whining you can try to send it back to service, maybe you will be lucky and they will solve it.

  Are you sure it's from the notebook and not from the power adapter?

• Hey Sharky, thanks for the reply.

  Im not sure if my problem is coil wine.

  The noise that is coming out of my laptop is not so fluent (more like you hear it really short several times after eachother). Like you are clearing your throat but then high pitched and not so loud...

  I first noticed it when i was downloading a game.

  So, if acer doesnt let you change laptop for this problem i assume it is not harmfull for you computer?

• Hi,

  So downloading a game eh? Well that means that the HDD was in use.. It can be the HDD sound. But I cannot tell you if the sound is harmless or not, and if you have time you should send your notebook to be checked. It would be better in my opinion than internet diagnosis.

• I read on the internet that ssd doesnt have physically moving parts, and by that it cant be the problem.

  Personally i dont know if this is true but im just noting it.

  I think i will just have to deal with the problem but thanks for you effort and time.

• Hi,

  Well if you have an SSD, then yes, it should not make any noise.

  But do you have just an SSD or an SSD and HDD?

• Hey Sharky.

  Thanks again for the reply.

  I have a ssd and a hdd, the hdd doesnt contain any files right now.

• I found out that whenever i move my mouse, this sound occurs, so its not random.

  So i guess it doesnt has to do with my ssd or hdd.

• Hi Karsten, check your energy profile. Setting it to 'balanced' should quieten the noise a bit. If set to 'highest performance' the noise is more evident. I dunno if it's coil whining but there are serveral laptops with skylake architecture suffering from this issue (dell xps 9550 too).
• my fans were also doing that I strongly recommend this temporary solution. just blow into the fans! that worked for me
  acer nitro 5
  8gb ram
  amd r7
  amd readon 500
