I was using my new (2 days old) Macbook Pro today (2.5GHz 15" pre-unibody) and it was working great, and all of the sudden, the screen gos black. The computer is still working, just no illumination on the screen. Like all of the LED's turned off. I'm new to macs. I also did a search but turned up nothing. Please help. I'm planning to take it to the apple store tomorrow. I purchased it brand new off of Amazon last week. This is really upsetting because I was falling in love with my mac... I can't stress this enough: Please help A.S.A.P.!
