Just yesterday I was using my Macbook Pro - with Word and MSN in use - until it gave me a black screen. (Good thing Word auto-saved.) The screen wasn't dimmed and the fan (or whatever was running) was still running. So I held down the power button to shut it down. When I turned it on again - and everything was okay - I thought it might have been the battery but yeah, it doesn't explain why the fan was still running. It's fairly new. I don't play games and I rarely watch anything on it. I'm also very protective of it and don't download much... Which confuses/worries me on why a black screen would appear. So does anyone want to share some insight on why this happened? Is it some 'normal' thing that eventually happens, because I've been looking around and found information with regards to this black screen problem and the Macbooks of those people seemed fine..
