Any idea? Bizarre phenomenon - Asus X5 series laptop

post #1 of 5
Thread Starter 
Hi,
I have an Asus X5 series laptop with 4GB memory and with Windows 7 Home Preimum on it. It is generally a very quiet laptop, as long as I don't open certain websites, such as gmail, for example (but there a few others as well). Let's stick to gmail for now. So, I open gmail, and within a second or two my laptop produces a weird (and annyoing) high-pitched/high frequency humming that is rapidly interrupted with short pauses (maybe this is the best description) - I will refer this as "noise". I close gmail and within a second it stops. It is not coming from the speakers and it is not coming from the screen. It is coming from where the power supply is attached to the laptop. By the way, if I unplug the laptop, leaving it to run from battery, this noise gets louder. I checked Task Manager and Resource Manager and I did not see any increased CPU or memory usage, so I guess it is not the processor or any fan. I tried gmail in Opera, Firefox, IE and Comodo Dragon, and it produces that noise in all four browsers (although is not so loud in Dragon then in the other three). If I minimise the browser to tray, the noise is still there. If I physically unplug the network cable so there is no internet connection, the noise is still there. Once the gmail is shown in any browser, the noise is there, no matter if the browser window is visible or not, maximized or minimized, if there is network connection of not, if the screen is turned or not, if the speaker is on or muted etc... Very bizarre... And now comes the best. If I move the scrollbar of the browser the sound stops as long as I keep moving the scrollbar. Release it and the noise comes back. Same with resizing or moving the browser window. As long as I am in the act of resizing or moving it, there is not annoying sound. If I release it, it comes back... Maybe it would seem weird, but it seems to me I can actually hear some kind of data movement? It comes from near the memory modules...
Thank you,
Attila

I managed to record the noise with my Blue Snowflake microphone. Please check this video: http://www.youtube.com/watch?v=Iz3BfrNSN2g
The first 10 seconds is the normal noise of my laptop (sorry for the mouse clicks :-)). Then from 0:10 to 0:22 you can hear the high-pitched "data movement noise". Then from 0:22 onwards (increase your volume) you can hear the extra noise that is left once I removed the base noise with Audacity.
