Aspire S7-392 backlight buzzing

It seems that some people had problems with the backlight causing a buzzing sound on the S7-391.  http://community.acer.com/t5/Ultra-Thin/Aspire-S7-391-Keyboard-backlight-makes-buzzing-sound/m-p/14459#M546

 

My S7-392 does it.  The noise comes straight from the keyboard.  It is frustrating because it is loud and really irritating like a mosquito.  I therefore can't use the backlighting (which is otherwise really cool) unless I'm in a noisy environment.  And how often does one use one's computer in a noisy, DARK environment...  Effectively, its like I have no backlighting, which stinks.

 

Does anyone else have this problem?

I have this problem also. Acer tells me to send my unit in, but I wanted to see if it was a design flaw like in the 391.

Would save me some time and money if anyone could tell us if they DON'T experience the problem, and it's just something we have to live with. Otherwise, I will have to send my brand new baby in, potentially for an engineer to say, yep, that's what happens with this type of back light.
