Great, thanks.

Someone here reported the BB models are not LED and are dual-lamp. Can anyone confirm this, and if it is dual-lamp would the screen brightness suffer?

So, this is a temporary fix that is still inconvenient. If Sony has an actual solution soon then it isn't a big deal, but if I had to deal with this issue for the next couple years I would not be happy.

Relax. Everyone appreciates your help but don't think that you stand out more than anyone else in this long thread. I posted a review about 20 pages back and nobody had anything to say about it-- it doesn't hurt my feelings. I'm sure somebody found it useful.

Oh I realize that, it was just I did not want it to get lost in a posting frenzy. Anyway, a little bit of encouragement seems to have worked!

Thanks for trying and rep added! So it seems it is defo to do with the mic. However physically disabling and rebooting does not fix it, only having the tab open all the time does, is that correct?

Actually try one more thing for me if you will please! See if you can mute the mic under volume options on the taskbar ( right click the sound icon, volume options ) Does it still make a noise then?

And, since I have been following this thread since it started and also the previous thread that triggered this one, I know of another solution that was mentioned in this thread. The solution was to disable the graphics driver.

If you're not playing games that is probably ok. Perhaps there are more solutions and perhaps configuring the graphics driver differently also solves the problem. Unfortunately I cannot test any of this since I don't have my F yet.

Edit: The first solutions that were attempted were to disable the C4 power state of the processor but unfornately tools such as RMClock don't support core i7 (yet). Also, there appeared to be no BIOS option to disable this power state. Perhaps someone can check again. Disabling the C4 power state is a known solution to solve whining problems for core 2 duo.

Another solution was to try to undervolt the processor but as far as I can recall that was also not possible using BIOS and RMClock. At least, no one did this yet and wrote about it in this thread.

Is there a way of checking whether an LED vs dual-lamp ? I see that my full-HD screen is evenly bright throughout.

I think there was a link very far back in this forum that had some material about how the new core i7's voltages could not be controlled by software (in Windows) and was managed on a hardware-level. I think the link also stated that the only way to change the power management was through a firmware or bios update. This probably means that people will have to stick to temporary fixes until Sony or intel decides to release a fix

Muting the microphone does not stop the buzzing either. Any other ideas? I'll keep fiddling around too.

I am on it! If you go to the microphone properties, there should be an option to disable microphone boost? Similar to this thread:

Loud Microphone Feedback During Startup

Also under power plan in power options, there is a little arrow you can click that allows you to choose high performance. Does that work if the mic thing doesn't?

Not sure, but I think that the screen is dual-lamp. Dual lamp technology doesn't necessarily have poor image quality/uneven brightness. The main benefits of an LED-back-lit screen are battery life and eco-friendliness.

Actually, the ease of the workarounds basically says to me that Sony would fix this very, very quickly via a firmware patch. Their engineers will do a deeper analysis and find out the root cause and send across a fix. I doubt we will have to be dealing with this issue for years.

Having said that, I need to point out that even though I heard the whine on the first day, I no longer hear it. Maybe I got used to it or maybe the sound just went away by itself, after the computer ran for a day.

Anybody with the core i7-820QM processor *NOT* having the sound ? Just curious.

Also, the user manual of the F (Sony USA site) explicitly mentions how to enable intel VT in the BIOS. I am now assuming it is there.

this sounds good

this sounds great

flumbo ain't the xp mode a win 7 pro option rather than the intel vt erik is talking about? or have I again lost something?
