Acer Aspire Switch 12 noisy LCD backlight?

Greetings,

 

Got my brand new Acer Aspire Switch 12 the other day. I'm very satisifed with the form factor and with the device in general.

 

Except for one thing.

 

There is audible amount of noise coming from my unit when the backlight is set between 0% and 100%. The noise seems to emanate just under the "Acer" logo. This noise goes away when i set the backlight to 0% or to 100%. And it seems to be the loudest if i set the backlight to about 50%

 

It is not very obvious but i can definitely hear it in a quiet room. Kind of defeates the whole point of a fanless design if you ask me. I think the noise is coming from the capacitors or coils in the backlight regulator circutry.

 

I would like to know if this is a general problem with this model or is this just a problem with my unit. Fellow Aspire Switch 12 owners, do you have the same issue with your unit?

 

Acer admins, is this a known problem with this model?

 

I have to know, i have to decide whether i'm going to replace the unit, return the unit or just stick with it.

 

I bought it from amazon.es.

Part number of my unit: NT.L7FEB.004

    mkatic,

     

    I do not see anything in the documentation that talks about that issue, you can contact Acer technical support in your area to see what your options are, or you can seek them through Amazon; I believe that this might be their return policy if it helps steer you in the right direction.

    I have the same issue (Intel Core m-5Y10C, win 8.1. 64bit). Also, I noticed that noise disappears when battery is being charged. So i wonder if there is possibility to eliminate it completely?

    It would be great to know if this is an issue that can damage hardware somhow or it is just the way it works.
