Hello! I am a happy Macbook Pro (2011) owner for over two months now. Some hours ago I had a small "fruit accident" when I went to clean the black screen connector I started hearing some sounds like plastic cracking. I also noticed the black plastic has a little arc towards the middle. When I close and open the screen I also hear some loud "cracking" noises I didn't before. Is that normal? is it cause of the hot temperatures the plastic expanded?
