This way you can remove the high pitched noise.
My friend had the same laptop and I fixed the problem myself.
High pitched noise comes from the inductors on the motherboard.
Intel invented a new energy-efficient processor, Microsoft included in Windows controls power processor,
and Asus is packaged in a notebook, but not very successfully.
IHMO, Asus engineers have made a mistake in the design of the motherboard, but they are not recognized.
The ideal solution would be to get a new model of the motherboard from Asus, but it is not realistic.
Therefore, we will correct the problem by means Microsoft (Windows 7).
1. We have to change the registry.
Typing in the command line "regedit", you go to the registry key:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Power \ PowerSettings \ 54533251-82be-4824-96c1-47b60b740d00 \ 5d76a2ca-e8c0-402f-a133-2158492d58ad
2. Included option in this branch will enable and disable the idle processor. In this case, it should be included.
To enable one or another hidden parameter, it is necessary to find and edit the value DWORD, changing its value SettingValue from 1 to 0.
3. Then, through the control panel - power - in the settings mode select power management processor.
There will be an option disabling idle processor and high pitched noise immediately disappears.
