I just fell my laptop its one of the Samsung Ultrabook Series. And I have searched through out the internet and did what they did. Then I backed up my files. Now I can hear a little weird grindling sound or scratching sound on the area where the internal drive is. I compared i to my sisters laptop (that wasnt broken) and I also heard the sound. You can only hear the sound when you place your ear to the area. What should I do? should I go directly to the service center? or what?
