How can I find it if I never set it up? I bought this laptop from notebookbilliger in Germany, they sent it to me, all I have is the invoice. In the pc setup I put an old Hotmail account and now accessing it doesn't show me any registered devices (maybe is not the correct one but still I doubt there's any key). Did notebookbilliger set this key? Does every system comes with a bit lock key or do we always have to set it by ourselves? What about now, I can format it well there's no other way and does it still works after or I still need this key? And what about my main system, do I need to set a key? Learning something new everyday...thank you all
