Display buzzing on X41 Tablet

[AShvydk]

I am soliciting responses from owners of X41 Tablet.
I just received a 18666HU unit and like it a lot. (Except
of cource very sloooow and constantly clicking HDD,
which I can live with).
But I noticed a constant, monotonous buzzing coming
from the display (or around it) area. It is much
noisier than the HDD and fan (which are to me are
silent). It is probably a transformer on the
invertor for the LCD lamp (I am just guessing).
My brother's T42 screen is silent.

Easy way to hear the buzzing is to put ear right next to LCD
and turn the display OFF and ON with Fn+F3.

The buzzing drives me nuts - to the point that
I am ready to send it back. I really like the
Tablet and am hoping that I have a
defective unit or something.

Please, guys, post if your X41 has this problem.

Thanks.

Wanted to add that the buzzing (medium pitched, I guess)
is not load and should be listened to in a silent room.
(It is not distructing in most of the situation, only
when I tried to read during the night, when it is very
annoying)
