Hello everyone!
I am new here and I have some question about my tx2z.When the screen is running ,there is a strange sound coming from the mid-left part of my tx2z. And I think it comes from the video card because when i adjust the brightness the loudness will change. It sounds like the Current sound, not very loud but I can still hear it clearly when my room is quiet. And it happens on the one I have right now and the old one that I have exchanged. Is it normal. should i exchange it again?
Hope someone can answer my question. Thank you very much!
Are yo talking about a high pitched squeeling kind of sound? It could be coming from a failing capacitor on your motherboard, video card or LCD power inverter.

Woohoo! I won my Touchsmart!
This sounds makes me crazy. Is there any solution to prevent this buzz sound coming from screen or capacitor. Then i turn of the lid, no sound..
I know this buzzing sound that you are talking about. If the screen brightness is set to 70% or higher the sound occurs. Setting screen brightness to 60% or lower might help, at least it does for my machine. Try it out by pressing the fn + f6 / f7 key.
So my guess is that the sound is driven by the backlight. Do you think this might be a problem that is serious enough to get the notebook replaced?
When it is silent, it is serious problem.. I love my laptop. superfast and good spec.. but i have to deal with buzz sound related the brightness..
