I have just got dell xps 15 from dell's outlet UK and everything seems fine so far apart from this tiny issue. A light Krrr noise comes from the laptop whenever I scroll down or up on certain webpages. Its not coming from the speakers as It still occurs while they are switched off.
It doesn't seem to happen on every webpage and seems to depend on the browser as well: Sound occurred while scrolling on YouTube on both IE and Firefox but on Google, the sound only occurred on Firefox.
Unplugging the laptop removes the sound.
Minimising the webpage reduces the loudness of the sound while scrolling....
And It doesn't matter how I scroll, whether by using the keyboard or trackpad. The sound only occurs while actually scrolling, so once I reach the end, even If I continue to press the button/attempt to scroll further, the sound does not occur.

I've read some similar experiences online and apparently this occurs mostly on flash heavy websites.

Any help on how to solve this issue or whether there is any real danger will be appreciated.
Thank you
