Airman's Official High Pitched Noise Fix!

I finally figured out a way to fix the high pitched noise problem without using the RM-Clock Utility. (If possible this should be made a sticky, thanks.)

This fix will work on 95% or so of effected notebooks with the persistant and annoying high pitched whining noise.

Before I begin, I just wanted to say that I have heard from so many people with newer notebooks that this is a problem with many notebook makers and not limited to any single company. This will not work on all notebooks because some may not be effected with this exact issue and may just have a loud hard drive, faulty LCD Inverter and so fourth. The exact cause is still unknown and most manufacturers won't even admit that there is one, and may say the sound is normal, but anyone effected will know that this is not the case.

So here we go,

1.) Right click My Computer and go into Device Manager.

2.) In Device Manager scroll down until you see Universal Serial Bus controllers

3.) Click the checkbox on the left, then scroll down until you see USB Root Hub there should be several of them depending on how many your notebook has.

4.) Right Click the first USB Root Hub and select Properties.

5.) In Properties select the tab all the way to the right called Power Management.

6.) In the Power Management tab there will be (2) check boxes, uncheck the first box titled Allow The Computer To Turn Off This Device To Save Power.

7.) Hit ok, the noise should now be gone, if not do this for all the USB Root Hubs that are listed in Device Manager and the noise will be gone for good.

Thats it!

If you are worried about the notebook not being able to turn off the USB Hubs to save power, I assure you that the power saved is not noticible and minimal to say the least.

Hope this helps some people out, take care and happy holidays!

Why not use RMClock?

Either way, disabling the processor from dropping any lower than C1E will have a considerable impact on battery life, and to do so only ameliorates the noise; it does not entirely fix it.

You are right that the problem is prolific. I suppose it a common problem to Core/Core 2 processors or the 945 chipset.

Edit: An alternative solution that requires RMClock and which supposedly fixes the whine without the effect on battery life is described here:

It did not work for me

 

Great tip.

 

Airman--- Would this method disable the usb device in anyway?

 

The tiny high pitched whine is mainly found in the newer 945 architecture in which intel has introduced new power saving states. The MOSFETs are to be blamed for this annoying whine...

 

No, it doesn't disable the USB devices, it simply doesn't power the USB Hubs down to save power.

 

Just got a new pavilion dv6235nr and it has the same problem. Wish I could just find O N E laptop that is reliable.

 

is this the sound that happens when you put a CD in.
because it sounds like the computer is going to take off into outer space.
I just customized a DV6000t with 2gb ram, and a T7200 processor, and i don't know what high pitch noise people are getting, but when I install a CD, the fan or something goes wild and the movement or vibration is felt throughout the whole computer

 

happened again today when I put in a CD.
is there a way to fix that?

 

u can use nero to control drive speed. or go to my computer /dvd drive right click /properties/recording and use your speed....its at the bottom

 

when i right click on my computer, i see no device manager... any help?

 

This solution will definitely hurt your battery life as the CPUs will not idle to the proper idle/sleep state (C3/C4). Use the solution described in the PCTabletReview thread on the first page. Works great without destroying battery life.

 

can u give us a link

Uses RMClock, but doesn't run an HLT command to keep your processor running at 100%. The solution in the thread keeps the USB ports powered and, due to a bug in XP, keeps the processor at C1 or C2. The solution in that thread allows the processor to fall to C3 or C4 as intended.

 

ok thanks, but can anyone help me with my previous question?

"when i right click on my computer, i see no device manager... any help?"

 

Right click on My Computer -> Properties -> "Hardware" Tab -> "Device Manager" Button

 

oh ok thanks

 

hey Airman

thanx for this posting regarding DV6000 series buzzing noise resolution.. however i have question regarding this. by doing this step would this harm my computer in anyways.. plz reply thanx

 

i tried to do this but they are unchecked already. i have a little tiny pitched noise. its not really 'bothering'but i think its better without it.

 

No harm it may cost a minute of battery life, but if you are like me and experienced the noise then I don't have to tell you it's worth 1 minute of battery life.

 

thanks.. your instruction is really easy to follow and done... i tried to use the rmclock like everybody else was talking about but couldnt find it lol (i tried to find "rmclock" using the search box but didnt work)
