While sitting at my desk, I stood up too close to the desk and a large wooden block (Actually a Wooden Block with my name on it, given as a gift but lets call it a block) fell off the top shelf of the desk and hit the Macbook. I wasn't looking at the computer at the time so I don't know how much damage it truly did, but I'm pretty sure it only had a single impact on the keyboard. There is a fair sized dent in the keyboard, and it looks like the center point of the cave in, is between the tab key, tilde key, 1 key, and Q key. It's enough of a dent to make the keys uncomfortable to use, as they are all slanted towards the center of the dent, however they are all fully functional. When it hit, I was using windows through bootcamp, so the gpu was being used. The only reaction the computer had, was the fan seemed to run at full blast for about a second, and then went back to normal. The laptop seems totally fine, but I'd just like to be sure. What hardware is under the keyboard in that area that could have been damaged, and is there anyway to repair the dent? Also, is there anyway to check to see if there's actually been damage done to the internals? I'll add pictures if you guys think it'll help.
