Laptop (HP, ASUS etc) high pitch noise.

I tried the solution below and it worked on my HP 450 G4 laptop,

Certain lines of Asus laptops emit an intermittent high-pitched noise resembling an electronic signal.  

The lines affected include the following:
eee PC 1201T

This noise has been variously described as a whirling noise, a chirping noise, a whiney noise, and a screeching noise akin to fingernails on a chalkboard.
This noise can be very irritating and have been the subject of numerous complaints to the company.  The company has not been very responsive to these complaints.
The good news is that there is a fix for this problem.  The process takes less than five minutes.  I’m no expert, but the following is what worked for me.  Follow these directions at your own risk!  If you have a better fix, please let them in the comments for everyone’s benefit.

Step 1.

Click the Windows Start icon, and in the “Search Programs and Files” field type regedit

Step 2.

Navigate to the following folder:

HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Control \Power \PowerSettings \54533251-82be-4824-96c1-47b60b740d00 \5d76a2ca-e8c0-402f-a133-2158492d58ad

Step 3.


Step 4.

On the top of the dialog box it should say DWORD

Step 5.

Change the 1 to a 0

Step 6.

Click on the Windows Start icon.

Go to Control Panel –>Hardware and Sound –>Change Plan Settings (for each plan that you use) –>POWER OPTIONS –>
Advance Power Settings –>Processor Power Management –>Processor Idle Disable

Set both of them to Disable Idle
