ok, three ways to kill the high pitch noise

from the previous threads.

1. RM clock, not recommeded
2. improved RM clock, the tablet thread
3. turn off usb power saving...

2, 3 which one is better?

@.@

Thx~~~

 

Turn notebook off.
Updating to the last BIOS helped mine, still there but not as annoying. And turning on about two or three USBs did most of the trick. Also noticed some improvement by disableing some services and processes. Or maybe i just got used to the noise.

 

i gotta hear this lol....so many threads on this topic. This whine comes from the c2d's only correct?

 

I have this issue too. I am using Core Duo.

 

Funny that the Core Duo laptops in the stores do not display this high pitch sound.

 

Yeah, i wonder why that is? i was at costco, and comp usa, and i tried my hardest to tune out all of the noise from the store and see if i could hear the noise, didnt hear a damn thing.

My favorite method for getting rid of the noise is just plugging in a a small usb flash drive. it gets rid of it almost completely. i pretty much always have some sort of external drive plugged in via usb anyway, so its not like its stealing one of my ports.

For some reason i cant always get the USB hardware check box thing to work. i just resently re-installed windows, and it worked on a previous install on a different HD, but not anymore.

 

maybe they use RMClock? or perhaps the noise isnt as easily heard with all the background noise or maybe they use the USB fix too

 

They don't use RMclocks in store, that is for SURE. When they put the laptops up on demo, they don't really play with them except set them up.
Where I work, I don't seem to hear anything than the normal whine of a laptop.
Granted, they are less used then when someone buys one =).

but I do agree, that when I have, lets say, a usb mouse plugged, I don't hear nada. Then again, I can barely hear that ee noise...

 

I thought the whine comes from the intel cpu's only. My amd doesn't seem to whine.

 

Hi all,

dont know, is the thread is dead already or not...

Actually I seem to have found one more solution to get
rid of this rather annoying noise.

OK, I've a T60 Thinkpad laptop and tihs noise appeared
as I put Windows XP on it. Before I had Windows 2000 pro
installed, and everything was fine -- there was NO noise
of this sort (high pitch, very annoying).

In most cases it (as many user threads report) occurs when
the laptop is running on batteries _only_ and usually disappeards
as you plug your AC adaptor in. (BTW now it's clear why they are
all so pretty nice in the shops and so annoying when we are back
to home ).

After doing some "research", "googling" here and there,
the problem is, primarily, a software bug in Win XP SP2,
related to the old issue of the power-drain being too
high while running on batteries and having a usb device
plugged in. Microsoft has provided a hot-fix for this bug,
but it does NOT resolve the problem of this noise.

Moreoever, this problem is also known to affect MOST of
Linux distros -- it's very well documented and described
here, at thinkwiki forum:

http://www.thinkwiki.org/wiki/Problem_with_high_pitch_noises

OK, now there seems to be light at the end of the tunnel:
I've had NO noise while using Win 2000, as Win 2000 simply
does NOT enter any of those C2/C3/C4 states, at least running
a dual core platform. But Windows XP does and it doesn't seem
to do that properly.

In my case I've actually tried all possible solutions reported almost
everywhere -- disabling power management of USB hubs, have also
tried to invoke the "HLT cycle" option in RM Clock, etc. It all was
just pointless, until I found _TWO_ options in RM Clock which DID
the trick:

*******

TWO MOST IMPORTANT OPTIONS TO GET RID OF THE NOISE:

go to "Advanced CPU Setting", open "advanced" tab and
UNCHECK "Enable Popup mode" and "Enable Popdown mode".

*******

Voila, it did the trick, the noise has disappeared at all.

I do not know _exactly_ what these two options are intended
for, but they are somehow related to bus master transfers, and
as most threads report, the problem lies just around this point.

Hope this will be helpful, just try and post here then -- will it do
the same for you?

Regards!

 

A couple comments as i have too indepth a history with the squealing, named piezoelectricity, by the way.

First, its not heard in stores because the noise level is just too high. This can also be said of many offices.

Its heard and pierces actually, in the comfort of a quiet room.

Next, I have tried and tested most all known solutions tht have ever been suggested. There is none that i feel are adequate as of yet. The latter mentioned here is similar to my last tests which reduced my battery life significantly.

It then brings us back to the question as to why we are fixing a brand new computer, being as it has effected desktops and aptops of evey processor make and manufacturer brand.
