Newer Apple laptops have a diagnostic program installed and it's on the boot disk (or USB stick) that comes with the machine. Reboot and hold the "D" key. After several seconds it will boot in the diagnostic program.
Yeah, that's what I thought. My usb stick is at the office- looks like a trip over there is in order.
Did the test, no problem.
Mine doesn't creak as others said, but I feel one side of the bottom cover is ever so slightly loose.
Called AppleCare and the rep told me the Apple Store Genius Bar now carries the special torx screw driver so they should be able to tighten it up on the spot. He said if that doesn't work, I can still get it replaced, but I kinda wanna keep this one since I have no other problems.
I'll drop by at the store on Monday and report back.
