Just got my MBP Back from Apple for screen replacement. has a 90GB Ocz Vertex 2 in it. however now when i turn the computer on it sits at a white screen for about 20-25 seconds, then the apple logo shows up and it logs in. total time from turn on to safari is 47 seconds. didn't use to be that long. oh when booting up theres no longer a spinning wheel either. any ideas?
