Hello I also have the same problem with my Acer Nitro 7 AN715-51 776F. Have you found a way to fix it?

Dragos90

I sent it yesterday to the authorized acer service from me in the country and I am waiting for an answer with the solution of the problem.

The ideal would be to send a video of the noise.

Dragos90

I uploaded the video made yesterday, listen best in the headphones please. The sound intensifies depending on how I scroll with the mouse

Does this noise occur when you plug in the power adapter?

Dragos90

It can be heard in both cases and connected and disconnected (on battery) I tried and from power management to put performance 99% the same sound ... nothing changes. The sound is present even in Bios

Dragos90

the answer came from the authorized Acer service in my country

"The laptop does have a sound, but it is a sound specific to moving electronic components and is not a defect that needs warranty repair."

so they sent it back to me as well

I am determined to make a complaint to the protection of the consumer (legal bodies) in my country because this sound does not seem normal to me considering that the laptop cost me 1300 euros

what do you think?
😭😭😭😭😭

I couldn't hear the noise well. However, it looks like something is scratching. Do you have how to record new audio? Does the same problem occur when resetting the lithium battery?

Dragos90

When I receive the laptop I will make a new video, I reset the battery and it does the same

surprisingly, it is also heard in Bios where normally no component is stressed

According to his report, the noise is coming from this region:

Dragos90

yes, from this area

I do not understand how to say that this sound is normal

what to do ?!
😭😭😭😭😭😭😭😭😭😭😭

Commodore_1995#

would it be a coil whine? how to record the audio again?

Dragos90

now the laptop is at the courier, when it reaches me I will make a new audio recording

Dragos90

Hi! I came back with a new noise recording

https://youtu.be/WuJTqcldg7U

please listen with headphones

the laptop was not repaired under warranty because the manufacturer acer reasoned that this noise is absolutely normal

as a result of what was said, I notified the consumer protection and I filed a complaint

Commodore_1995#

I heard the noise. Now, does this noise occur when you use an external mouse or touchpad? What is the version bios?

Dragos90

The noise is present and without using the touchpad only it is quieter
I tried with 2 external mouse , 1 with wired and 1 without wire (wireless), the same noise

I have the latest bios version on the acer site (1.29)

I don't know what to do to get rid of this annoying noise ... the service acer doesn't want to fix it for me, it says the sound is normal
Does it seem normal to you?

Try resetting the battery. To do this, turn off the notebook, disconnect the power adapter, and then press the power button for 12 seconds.

Dragos90

I did exactly as you told me, I reset the battery, but no change in noise

Commodore_1995#

In my opinion, this noise is not normal. What happens when you limit the processor to 99% on power options?
