Hi! I have an MBP 2.4 SR with the defective nVidia video. I would like to get it fixed since I am now having issues with the screen going black in the most inopportune of times, sleep issues, etc. When one goes to get their laptops fixed, should one save all their data into another hard drive, clear the laptop hard drive, reinstall OSX, and turn in the laptop with no data? Or does Apple have a way of fixing things without having admin access to your hard drive? Thanks!
