VPCZ2390 SSD making noise

Hello!
I have a question regarding SSD noise in my VAIO VPCZ2390X.
When I perform disk related tests - antivirus scan, or downloading large files from internet, my SSD starts to make screeching noise. It's not very loud or anything, just a bit annoying.
But SSD disks are supposed to be quite...
What do you think might be wrong with my laptop?
Thanks

 

It can't be your SSD. At worst, it could make electronic noise (which sounds like a very vague whistle - you can hear the same when putting your ear near to a cellphone charger). Any screeching comes from either the laptop cooler, optical drive, or hinges. Many times, disk related tasks take a fair bit of CPU power... maybe your cooling fan is acting up?

 

Cooling fan works fine... It's definitely SSD disk - I checked. I.e. I download large file from internet, or perform disk related tasks - I can clearly hear noise. It's not a fan, nor mic/sound. Checked those too...
And it seems that vaio care hard drive check does not work - it says - RAID drives are not supported. I started test 15 minutes ago - it still says - scanning for supported drives... And there is no progress.
Windows error checking of hard drive does not find any problems.

 

Believe me or not, it's not the SSD, it is the power converter unit on the motherboard that makes the noise! It uses coils and capacitors to supply energy to the CPU. When the CPU switches between c-states during random disk accesses, website scrolling etc., its energy consumption changes momentarily and current peaks in the converters make parts like coils vibrate at high frequencies you may hear in silent environments.

Basically you can't do much about it, there are however workarounds to prevent it:
Check if you hear this sound running on battery or AC. Then use your laptop with the respective power source.

Try changing windows energy profiles and its CPU options, when running full power, the noise should be gone
You can install my hacked bios to disable c-states completely (higher battery consumption, faster ssd speeds) or use a software tool to disable c-states.

Hope that helps.

 

Thanks!!! I checked - when on Battery with "power save", sound disappears completely. So, that is not SSD.
Could you please recommend software? BIOS hack sounds very dangerous... If I use this software, can I turn changes off?
Thank you

 

Besides, will full system recovery help? I need to use recovery disks to full wipe + re-install my operation system. May be the problem will be gone?
Will it help if I bring laptop to service center? Though I very much doubt that, unfortunately...
Thank you

 

Try throttlestop and play with the settings, you can't break anything. Search the web for similar software - I never experienced this noise on any of my vaios but on my lenovo T420. However it is very silent so I can live with it. I have many ac adaptors that do this noise even if nothing is connected to their DC output plug. I once opened one and filled the coils with epoxy glue and all screeching noise was gone. Hell even my fridge does some kind of bubbling-screeching noise. That's the price we consumers pay because we want it cheap!

If you are still on warranty, complain the noise, perhaps Sony might replace your motherboard but I don't think so. They will probably tell you they can't reproduce the issue and do nothing (search the forums for after sale service experiences with sony, it is nothing short than terrible).

Doing a clean install of windows or a recovery will not help because your issue is not a software problem.

As I described, controlling the CPU power states and/or frequency by software like throttlestop is the simplest thing to get rid of the noise.
