I had some visitor to our home and they made a similar mistake. They put their macbook pro in the seat of a chair with a jacket almost covering it. I spotted the corner of the laptop then his mom and I did what some would call an intervention. Floors and chairs are no place for laptops.
You will only know if it works by turning it on.
Just a few minutes ago, my 4 year old brother (40 ish) pounds stepped on my Macbook with the lid close right on the Apple Logo! Do you think anything would happen because of it? I don't see anything wrong with it or any cracks, etc.
