Lenovo P500 - strange noise

Question

So, I bought a 15.6" Lenovo P500 laptop today. When I powered it up, it right away started making these strange, "staticky" noises - like paper crumpling and a few clicking noises. Thought that was very strange. I had played with a few brands of laptops at different stores before I bought one and never heard any one of them make those kind of noises, even the Lenovo ones at the Best Buy showroom floor. I also noticed that the sounds are coming from the upper right side of the laptop, around the area of the optical drive. And that the sounds are more louder when I'm surfing the web via wifi. At the initial start up the sounds were more loud (but not that really loud) but as the day progresses the sounds were becoming more quieter and it comes and goes. But it still continues though here and there. What the heck is it and how can I stop it from doing that? I mean, when it's not making those noises the laptop is really quiet, even when the fan is on. Sometimes I think that I can live with it since it's not all the time but when it starts up again I think to myself that it could potentially become a fingernails-on-the-board-kind-of-thing. It could really become very annoying very soon. Anybody here experience the same thing with a Lenovo laptop? I really like this laptop from what I have seen so far and I would really hate to return it but the noises are starting to get on my nerves.And it's only the first day. Don't get me wrong, it's not THAT loud but it has the potential to be very annoying sooner or later.
I hesitate to return it and exchange it for another one of the same brand and model because if it turns out that the replacement laptop also has the same problem then I will be forced to return it AGAIN and be liable for a pretty hefty re-stocking fee (from what I understand). I have never had to return purchased computers before in my life as I've never gotten a "defective" product before so this is all new and confusing to me. And I really like this particular laptop. I could exchange it for a different brand but I'm saving that for the last resort. I hope. So, if I can fix this I want to do it before I return or exchange. Any ideas?
I've read on the Lenovo Support site that more than few people have had or are having the same strange, staticky noice complaints but those were from a different Lenovo model. They said that it has something to do with the audio driver and microphone settings. But the static sounds are more pronounced when they are using earphones while watching a video or listening to music. They can hear the static noise through the sounds in the earphones. I don't have the same problem. My sounds are perfect with the earphones. The laptop is still making the static noise but it's not translating in the sounds from the earphones. I can't hear the static noise when I have earphones on even though it's still making the sounds at the time but wearing an earphones all the time so I can't hear the static noise while working on a laptop is just ridiculous to me.
Any ideas or suggestions? I would really like to fix this before I decide to give up and return or exchange it so any help would be greatly appreciated.

No restocking fee? That's good to hear. Because I've read from another site that someone bought a Lenovo laptop (different model I think) with the same clicking, gurgling, static sounds issue and had to exchange it for another one (same brand and model laptop). Unfortunately, the replacement laptop had the same issue (same static noise) and when he brought it back he was charged a restocking fee and he also ended up buying a different brand laptop. And I would really like to have this same brand and model laptop if I were to give up on this one but am scared that the same situation would happen to me too. Is that the case?
I'm going to give this one a few more days hoping it would miraculously fix itself or the noise would somehow make itself disappear. It's still making little clicking noises as I type on it though. I would be somehow disappointedt if I ended up with a different brand laptop though as this has really grown on me.
