Hello,

I have a new problem with my Asus G752VY. Whenever the speakers are activated to play sound (or not, the sound itself can be muted, its all about the fact that speakers are working), apart from sound, there is also quite loud screech coming from the left part of the laptop (around F1/F2 keys). It is really annoying and I want to know how to stop it. I have noticed that when laptop works on battery, there is no aforementioned screech.

Uploading the audio recording with the screech (I was clicking the speakers slide in order to generate a sound, use headphones to hear it more clearly):

Ok, so I figured out how to turn off the high pitch. It's coming from the CPU and it is a problem that MANY laptops and PCs are facing. Solution: http://asusnoise.blogspot.co.uk/ (it works for all other ASUS laptops that have this problem).

Nonetheless, the solution to the problem makes new problems:

Processor Idle Disable function, when its active, regulates the CPU usage. Thus, our CPU can work e.g. on 3% of capacity. But, if I set it Disable, the CPU momentary hits 100% usage, and allocates all available resources to every process (e.g. suddenly Firefox starts to drain 60% of CPU power, and calculator 40%). Apart from obvious power waste, in case of laptops there is another problem: the fans will start working constantly at the "full throttle", thus its much more loud and annoying that the screech I was tried to eliminate...

Any bright ideas? Is there any fix to this Processor Idle Disable problem? Or should it be like that?

PS: the easiest way to deal with the problem is either work on battery, or switch to Power Saving program - both of them immediately eliminate the issue.

Install throtlestop and activate speed shift. My guess is that'll help you. And while at it make some undervolting.

Read my "guide" one this topic:

I'm afraid installing "clean" copy of Windows 10 is not an option, because lack of Sonic Suite 2 makes my speakers sound awfully hollow. Also, I'm afraid to do any OC changes... I have no clue how to do it :/

No problem, just do the other parts. But you'll have to uninstall rog center.
