I faced same issue as many of others here. I noticed that something is not ok after first day at work, say after 6 hours. With little of concentration I realized that the notebook sqeals around CPU/GPU area.
I went to Lenovo certified service next day asking them, if this behavoir is normal or I got bad piece. The service guy did a single hearing, shrug his shoulders and offerd me to try his X201. It was same story !!!
I came back home with frustration in my head, that after a month of finding new notebook for next couple of years, I have got expensive piece of HW which can't be used for daily work.
Fortunately I went accros this forum and was able to stop the sqeal in BIOS ... but dear engineers from Lenovo : other notebooks (e.g. DELL) with same CPU does not have such a behavior .... so where is the problem I ask ?????

I noticed this problem with a brand new W510 (i7-820QM) from day one: a high pitched intermittent sound, almost like morse code, most noticeable when on battery and in quiet environments. The person next to me on the couch could here it too.
Here's a recording, amplified to make it clearer:
The sound was so annoying I put the laptop away after an hour. It was absolutely pissing me off.
I found this and other forums and discovered the sound would go away when the CPU would not be idle (i.e. playing music with speaker muted). Disabling power management in the BIOS helped as well, but the decreased battery lifetime made this an unacceptable option for me. Disabling 'Deep Sleep' in the Power Manager didn't seem to help for me. I also upgraded the BIOS (to 1.34), Power Manager (to 3.31) and the NVIDIA drivers (to 260.99): didn't help.
I sent it to Lenovo's Service Center and since then got very frustrated with the speed and service they helped me with. It has been two weeks and I still don't have my laptop back. I have been on the phone with them almost daily, but they would/could not help in getting me a new laptop.
Yesterday I called Lenovo to cancel the whole thing. The laptop is going back to the reseller and I am getting a refund.
I am extremely disappointed with Lenovo. I was expecting high quality hardware for my 2500 euro and professional customer service.

My wife is complaining about the noise on her new W510 w/ i7 820 processor.
It doesn't bother me, since I can't hear it
(being older does have some advantages)
Thanks for the recording... She found it very irritating.
I really don't want to replace the machine...
Hopefully they will have a fix, other than disabling the Deep sleep.
How much battery time are you gaining with the Deeper Sleep option?
If the difference is negligible, then we can just disable the feature.

I have also bothered with this... No option to turn down any power saving features - the battery capacity on this (beside the issues) great laptop is not good from start of. The sound have reduced somewhat in intensity after getting all the software into the box, but still extremely annoying. The loud fan noise on my former HP was peanuts compared to this
I will try for a warranty request on this after a periode.

Dell Precision, HP Elitebook and others with i7 processors are affected. If possible, change processors (same type, but another 1), as production may not be 100% consistent. If you are lucky enough like me, you will be able to change to a processor with much softer whine/squeal sound or even no irritating sound at all.

My workaround was to create a 4 hours long silent mp3 (encoded at bitrate 5 to reduce space) and to play that file with mplayer whenever I want to stop the whine.
This has several advantages over disabling CPU power management:
On C3 CPU stabilizes itself on a temperature around 50 degree celsius (while on C4 may drop down to 40), but this is the price to pay for a quiet laptop.
