When i turn on my ibook the grey screen appears with apple logo and the circle thing below it. After about 5 seconds it turns itself off. It does this every time?

Just kidding, I know you meant to type out the word "failure", correct?
Anyway, what kind of iBook is it? If you have the original install discs, now would be a good time to use them. How old is your book and what's on there?
That's called a preen, when fsck is running and attempting to make sure the file system is intact. If it's failing (and shutting off) that's not a good sign.
As noted by the poster above, you should be booting off your installation CDs/DVDs and running Disk Utility to repair the drive.
That means they probably messed something up and you should call Apple immediately and tell them how it was like when you got it back. This way they won't hold you accountable and you can tell them that they're the ones that broke it, not you.
