I was hoping I would never have to send my MBP in - but all good things must come to an end. I oredered it the day the C2Ds were released and have been pretty happy...until now. When I opened my mac this morning it sounded like a stick in the spokes of a bicycle wheel - if you catch my drift. I heard a similar sound on youtube, someone recorded it. It only happens for a little while (maybe 20 sec.), then goes away. It has happened twice now, so i decided to call applecare and they are sending me a box. As a med student, this will be tought to part from..she said 7 days at the most...is this accurate? Also, does anyone know about the cause of this noise? and why it would go away after 20 seconds? I guess I am just looking for similar incidents - couldn't find a lot on my search. Thanks for any input.
