Have the company sending it pack it and insure it. Make sure you insure it with the right option so that if your laptop is worth more than their limit, it will still be covered fully in terms of money.
You want to pack it? Packing peanuts, those things with a bunch of bubbles that are fun to pop if your a kid, ummm.... if you want some really good packing you can get some cheap pillows and use those too... but thats going a bit too far
Oh yeah, when you pack it, make sure the laptop is in the center of all the packing, not a side like another idiot
