Hello, my dad bought me a very nice HP Pavilion Entertainment Laptop for Christmas, and I have been enjoying it greatly.

Around a month ago, I noticed there is a small, half a centimetre dent-like mark in one part of the screen that makes the area it covers slightly darker. When I turn off the laptop, I can't see it, but when it's on, it appears again.

I am scared to tell my dad, so does anyone have any advice?
