Random noise problem

[dm01]

Hello, my english is bad but I try to describe it. I have MSI CX61 2OD notebook.

My notebook has random noise, it comes like from "left speaker area". I muted speakers and disabled sound card but noise keeps coming.

It's not like HDD noise, more like a " cızzzt" . It's coming always in same tone and same length. Both on battery and plugged in.

I recorded the noise here is the link: noise.mp3

What should I do? It's coming completely randomly. A user from MSI forum said its because of "a short or arcing around the Charging jack"

Is it true? Please help me... (and I don't think the noise is coming from the fan)

Hi, is your HDD near the left speaker? I think the sound is coming from your HDD, it's like your HDD is parking the head when it's not used, I could be wrong.

I don't know where is the HDD. How can I reproduce the noise myself ?

When you start you laptop, do nothing with the laptop and wait a while, after windows loads all the programs, you will hear the sound after a few minutes, if the sound are the heads moving out of the platters.
