Coil Whine in Asus Laptop from intel HD graphics 530

[RGóme1]

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 (http://vocaroo.com/i/s1Y3CV2BcPQO 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!

Hi,

I have listened to the audio and does seem really strange.Let's start by updating to the latest graphics drivers available https://downloadcenter.intel.com/download/26464/Intel-Graphics-Beta-Driver-15-45- here they would be version 4552It will be good if you could test customized drivers from http://www.commercialsupport.asus.com/downloads Asus and let us know if both drivers are the same.Allan.

I have downloaded and installed both and nothing changes. This is the driver in the Asus page. Thank you very much for your answer

Thanks for the information. After loading both drivers, you see this is not a software issue. This seems to be hardware and the best way to check it would be contacting your computer manufacturer.

This is the contact information from Asushttps://www.asus.com/us/support/callus https://www.asus.com/us/support/callusAllan.

But, if it's not a software issue, why is it solved when using Ubuntu or running Intel utilities on Windows 10?

[idata]

Linux* and Microsoft* operating systems do not carry the same graphics engine. It might be that when using different operating systems the graphics frequency changes and that is why you are getting this high pitch noise, again, hardware issue.

and how about the Intel applications? Yesterday I installed a Virtual Machine with Windows 7 and no coil whine

Since the graphics is integrated on the processor. You could try running a test and this will let us

know if the graphics portion of the processor has something wrong.https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool Intel® Processor Diagnostic ToolAllan.

I downloaded and ran it and everything was ok. Thank you so much!

Good to hear this is working for you. Thank you for the update.

Hi again! I have made some importants discoverments. First of all, with Asus Live Update, there is no whine. But the most important changes are due to Power Plans in Windows:

With economizer there is no whine, and with high performance, a lot (with balanced, I can sometimes hear noise). But by changing some of the values in advanced settings the whine is gone. Specifically, in the Process Power Management: increasing (above 70%) the Minimum Processor State will cause coil Whine in Economizer mode to appear, and decreasing in Balanced mode to reduce it. Changing this and the other values in Process Power Managament has no effects on the High Performance plan (no noise reduction). Any idea of what is happening?

Thank you for the information, this is really an odd situation, I just keep thinking this is not a driver issue.

I think is a good time to contact Asus for hardware support.https://cms-am.asus.com/ecp/Rma.html Asus supportAllan.

I have already sent an email to Asus Support. Waiting for the response in 48 hours. Thank you again!

I have similar issue on my Dell Inspiron with the same Intel GPU.

You are lucky as you do not have Optimus technology used, therefore the sound is not very loud.

You could try using only Nvidia GPU (by disabling Intel GPU in BIOS) or try to disable C-States (in BIOS too).

[RGóme1]

I read about disabling C-States in Bios, but I have no option to configure CPU settings in my BIOS menu. Also, I have no possibility to disable intel GPU. Do you know why?

[BKono]

ASUS does not allow to change it in BIOS, I guess.

You could try looking for modified BIOS on the Internet or modify yourself, but I am not sure if it is safe.

As do you not have Optimus technology (as far as I know) - you can try to disable Intel GPU in Windows Manager - it should work too.

[RGóme1]

I have disabled Intel GPU in Windows Hardware/Device Manager and no changes. My brother has the same laptop, and yesterday I discovered that it also had this annoying noise. So I imagine it's a problem with this model.

Thank you!

[BKono]

Strange that it did not help.

If chrome and other applications are running on Intel GPU - could you try running them on Nvidia GPU?

Also, did ASUS reply to you?

[RGóme1]

Nothing changes when running them on Nvidia GPU. Asus has replied me today, but they haven't told me anything useful. I am seriously thinking that the problem's origin is the CPU.
