How to completely restore your MacBook Pro to factory?

Reinstall Leopard? That should do it

Reformat and reinstall Leopard will do so.

By default, popping in the system disk and rebooting into that will give you an option to upgrade or perform an archive and install which will preserve your home folder. This is a great option provided you want that, otherwise if you want a pure factory fresh restore, then you will need to reformat the hard drive.

****Warning doing so will cause you to LOSE everything, so first make sure you have your system backed up and second are you sure you want to do that?

Thank you for all the responses. It is not quite what I was looking for, as I explained I do the 7 pass erase, it erases everything from the hard drive and reinstalls everything fresh. But I was wondering if the memory or some other part of the computer retains information which would cause the computer to slow down? If so, how would I go about erasing that.

Why do 7-pass? If you were selling or replacing the HD, I could understand, but isn't this total overkill for a reinstall? Multiple passes are for security, from my understanding. I can't see how they'll affect perfomance at all. My Mac's stay pretty peppy from overall good maintenance (especially not installing too much unnecessary crap). I also keep a lot of things on external drives to try and reduce system disk clutter.
