Vaio high pitched whining noise VPCCW27FX

The whining sound coming from this computer ( Sony Vaio VPCCW27FX ) is really getting annoying.
I bought one and returned it and got another one hoping this one will come without the whining noise, but i was wrong.

I tried all these steps suggested by other users:

• I tried the muting mic. through control panel. didn't work
• I tried to Go to systems -> Device Manager -> Universal Bus Controllers, it

reduced the noise but didn't completely cut it and plus my mouse stopped working.

What I found out was, when i boot the laptop in Safe Mode, the noise disappeared. I don't know what else I should do.

 

Is your laptop running on battery with the power adaptor unplugged when the high-pitched noise appears?

There are known issues about high-pitched noise on Core iX processors that affect various brand of notebooks. I heard the sound is only emitted when the processor is in low-power mode, thus plugging in the charger usually make the noise gone.

 

No, it makes the noise when its plugged in and the noises increases when I unplug it as well.

 

The best you can do is compare it to other CW if they emmit the same noise, preferably the one with the same processor as yours.
I'm curious, since I heard the noise only present if the processor is in low power mode, maybe you can set your power setting to "Performance" instead of "Balanced" see if there's any difference.
The noise is on my computer (Vaio E) only present when I unplugged the power adaptor, but it also could be because my ears are less senstive

 

hello...I have VGN-FW21E and the sound that you're describing maybe due to the constantly working fan! i have the sound too, and it's very annoying! I hope sony will update the bios for this issue that is very common in vaio laptops, don't know what sony is waiting for!!!

 

Nope this is not a fan noise, its a processing sound either coming out from the cpu or the graphic card and as i mentioned above when i boot it in safe mode the noise goes away.

 

The CPU/ GPU whine is normal. I returned 2 laptops because of this issue, and the 3rd Vaio FZ didn't have this. But I am hearing it sometimes now and got used to it. The noise goes away in safe mode because the GPU driver is not loaded in safe mode.

 

ah finally something that makes sense, do you know how it can be turned off when windows is running?

 

The whine is common among laptops using Intel processors dating back to the Core Duo chips among any laptop manufacturer. It's not a Sony issue, it's an Intel issue. It happens when the CPU is idle and drops its clocks and voltages into power saving modes, the lower voltage causes an electronic capacitor resonace, which produces the sound.

That's if you're referring to the same whine - if it is the same, you should notice that if you fully load up the CPU, the noise stops.

 

actually it has absolutely no effect. no matter if it runs on power saver or performance or I watch a movie or let it sit there by itself, the noise keeps coming, unless its on safe mode.

 

Power management profiles won't affect it, they don't actually change the behaviour of the CPU. And watching a movie barely puts any load on it. Try using Orthos ( http://www.techpowerup.com/downloads/385/Orthos_Stress_Prime_2004.html) - if the noise stops when this is running and the laptop is plugged in, it's the CPU and a normal noise. If not, it's something else.

 

I FOUND THE ANSWER I FOUND THE ANSWER!

I just bought my VPC and immediately noticed the high pitched noise; you're right it's not the fan, but more like a whine or feedback or something.

Turns out it's the microphone, not the Intel chip... at least my high pitched whine wasn't the chip. I found the solution here:

http://www.sonyinsider.com/2010/01/...untering-buzzing-or-high-pitched-whine-issue/

But if you just want to know how to fix it:
Go to “Start,” then “Control Panel,” and then click on the “Hardware & Sound” category. Then click on the “Sound” category, and then click on the “Recording” tab. Highlight the microphone and go to Properties. Select the “Listen” tab and “Mute” the mic as well as put a check mark where it says “Listen to this device.” That should fix everything. When you want to use the mic or webcam, just undo these settings.

Hope that helps!

 

I have a Sony Vaio E series PC which I got a week ago. I believe I have the exact same problem in that the noise coming from the comp becomes louder when on battery.

I did a detailed "checking out" of all available options. The one with the "microphone fix" does not work, however.

My Solution:-
I unplugged all my usb ports and had the usb settings in the power settings profile set to "enabled" (this is for the selective disable feature).

My main buzzing noise has now completely disappeared.

I am not sure whether this will be a solution to everyone, but on my laptop I think the buzzing noise may relate to the earthing/wiring of the usb ports.

I guess in the longer term I might just get a bluetooth mouse.

 

Ok thank you for the replies. I made some improvements in solving the problem ( or at least a band aid for this issue)
it is NOT the common microphone problem, but there are couple of applications that causes the noise.

Solution: Disable the YAHOO MESSANGER and GOOGLE TALK. it reduced the sound by 99% for me.

I don't know why they cause this noise but I'm 100% sure its from them (at least for me it was)
Disabling the USBs help but then your mouse won't work.
So Disable any messenger you are running (yahoo, google, msn, aol etc....) and see if that would solve your problem.

 

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.

 

This really works!

 

Thank you so much! This issue was driving me crazy. Your solution worked instantly... the high pitch buzzing noise is gone. Thanks again.

 

Yes it works but in expense of putting 100% load on the CPU therefore increasing the internal heat, resulting in kicking in the fan in high speed!
until there is solution for that I will disable my messenger applications.
This appears to be an hardware issue and i don't think there could be any solution to this problem.
One other thing i do to avoid the noise is to type msconfig in the run window and disable all the running application from the start up.

 

I've noticed the same problem with fans being much louder and the CPU staying at max frequency all the time. I think the only real solution can be provided by Sony through BIOS update :/.

 

Hi, I turned off the C state support in my BIOS and the noise (tinnitus noise i.e. high pitched noise) got a lot lower. Now I can actually use the Vaio without the power adapter.

The fan speed does not increase as tweaking the power settings causes it to do, as per above.

Would you explain how you have done it?

 

Press either F2 or F3 (depending on your model) while the first 'VAIO' logo is displaying when the machine is booting to access the BIOS. The option to disable C3/C6 state should be there - if not, you either need a BIOS update from Sony or your model doesn't support it.

Bear in mind though that what this does is disable the CPU's power saving states, so it'll be running full throttle all the time and impact your battery life.

 

Not really and not full throttle (full throttle it does if you do the trick in power saving options in windows described earlier in this thread). And if 2 states turned of decrease my battery life with some minutes when the computer is just being idle - I really do not care.

My brother has same issue with his i5 (my vaio has i3) CPU on another computer than Sony but this also helps him as well as turn of vsync in the graphic card driver settings.

 

ME too got the same problem
Now fixed, thanks folks.
It was the mic.I had plugged in the headset and mic used on yahoo,and shutdown.

When i restarted,(unplugged the mic) then there was this strange noise.
Suspected if it was a cpu setting issue/ disable ide power.
But actually unlisten the mic solved the prob.

My CW makes a high pitched beep followed by a click...If I'm watching a video while this happens, the video freezes then resumes after the click. It happens at random times. I've tried changing the CPU settings but that just makes the fans run very fast. Is this the same issues everyone else is happening? Is the beep followed by a loud clicking noise?
