I have a thinkpad x61 tablet that makes a whining high pitch squeal noise whenever I drag a window / scroll window / and some random times.
Previously, I was able to notice noise when I enter screen saver mode when I have rotating text message on the screen.
Today, I just found out that when you visit this sie, it sound like the maximum noise produced from my thinkpad.

Then click 'gallery' on the left menu. The noise will be there even with the internet explorer windows minimized.
The amount of the noise comming from the motherboard is unbearable.
I know it's from a electronic part because I tried my thinkpad with the keyboard and palmrest taken off, with USB keyboard connected to it. I also have a SSD that is noiseless.
This happened with both XP and Vista 64.
I also have another same model CTO7764 thinkpad x61 tablet, it still produces this same type of noise but is much quiet.
I'm sending mine in to the depot next week for a repair.

EDIT/UPDATE:
I should have posted an update much sooner, like a year ago. After I got my motherboard replaced, the noise is gone. The noise was coming from a circular device which looks like a capacitor.
