So I have recently been having a few issues with my non-retina Macbook Pro 15". It is still under the 3 year AppleCare+ warranty until mid summer so I plan on using the genius bar once the semester ends. So anyway here are the issues. 1. It overheats when I shut it, put it in my backpack, and go to the next class. When it overheats, it shuts down automatically and refuses to start until I open it. It has only been doing this for a month or two, but its pretty inconvenient and I don't want to roast my Mac. 2. When I lift it from the bottom while open, specifically one hand, the screen distorts in a colored static appearance and then locks up. I have to restart it to get it to work again. So any ideas as to what these could be? I plan on taking it in soon, but with finals coming I need this computer before it gets turned in for repair for time. Thanks for the help and suggestions!
