Whenever I tilt my 13" macbook pro, I hear a rattling noise that sounds almost like glass is stuck inside my computer. It is only when there is a severe tilt. In addition, my keyboard is no longer lighting up all the time, only randomly or when it is tilted occasionally. Otherwise, it is running perfectly normal. Is this a problem that will result in future issues that may be severe? Or a severe problem itself? It is still under warranty, so I do plan on taking it to Apple. Only problem is that my school is 1.5 hours away from a genius bar, and I am currently working on my thesis until next week. Did anybody else have this problem? Did they have to send out your computer? I really would prefer not to drive three hours total to take it to a genius bar if I can wait until next Monday without any severe problems, and I really hope they do not have to send out my computer at the end of my thesis. Any insight would be greatly appreciated!!
