hi guys, i bought a few days ago a new MBP, it's the 2,53ghz with a 7200 rpm 320gb hard drive. it is absolutely fantastic but i'm experiencing a little problem: sometimes when i flip up the screen for waking it up (it doesn't matter if it's been sleeping for 10 minutes or a whole night) instead of being quickly ready as usually macs do, the screen becomes black & white and it needs about 15 seconds to get ready. i have absolutely no explications for this behavior and i hope someone will help me. i'm also uploading a video on YouTube to show the problem. EDIT: here it is: http://it.youtube.com/watch?v=MepirdiMajc thank's a lot, bye.
