It's a start. Here's what I've found:
If I search on the HP website I cannot find it. I even changed to searching the US site instead of the Australian site. (hehe)
If I search Google it brings up a lot of different specifications of the same model. And they all seem to say that it is a refurbished unit. So basically what I am looking for is if there is any more code after what you gave me. Do a Google search and you'll see what I mean, 463549R-999-xxxx
<--- where those 4 x's are more letters/numbers to define the exact specs of the model.
But like I said, it's a start.
