I bought this laptop three days ago, and there seems to be a deep scratch on the gray part of the cooling section on the back. I haven't experienced any problems during my tests and games so far. Will this scratch cause problems in the coming days? What does the gray part I marked do, and what is underneath it? Should I return it?
