I need help with coil whine in Asus laptop

Jan 20, 2017 1:51PM PST

Hello to everyone!
This is my first topic on this forum, and I expect you can help me with this annoying problem that has been disturbing me for some days.
Recently, I bought an ASUS R510V laptop with freeDOS as OS, 8 GB RAM, intel i7 6700HQ, GTX 950M as dedicated GPU, and intel HD graphics 530 as integrated GPU.
About 2 weeks after installing Windows 10 and Ubuntu 14 I realized that, sometimes, a high-pitched noise came from inside the laptop (hear the noise). Surfing the internet I came to the conclusion that is coil whine, and I think its origin is the intel integrated graphics. First of all, this noise is produced only while using windows (not in ubuntu, where I can only use GTX 950M GPU), specially in the screen that appears when an application needs special permissions, or in applications like Google Chrome. I have updated my Intel drivers too.

But the most strange thing I have discovered recently is: this noise does not show up while the Intel Driver Update Utility or the Intel Graphics HD control panel are running in foreground.

Do you have any idea why is this happening? Any suggestion to solve this problem apart from having Intel Driver Update Utility or the Intel Graphics HD control panel running?

Thank you so much anyway and sorry for my English!

For decades, coil whine is deadened with shellac.

It's such an old issue that I hope you can google how to shellac coils and find the old TV tech coil whine spray on google.

-> There is another issue. I worry that Asus may not warrant operation on other than the supplied OS. Try this model that came with the OS you want to run.

Thank you so much for your answer. I forgot to tell that my brother bought the same laptop, but with Windows 10 pre-installed and he is not suffering this issue. I was thinking about a solution which consists of having those intel applications (or some of their processes) running in background. Any idea?

Sorry I have to disagree.

If you claim it's the same install and settings, it's hardware. I find some folk very sensitive to noises so much so that I've had folk returning laptops due to HDD seeking noises (which is a normal noise.)

Some folk won't have it.

At this point you have to deal with the maker.
