If you'd have given the exact model, I or someone could have easily found the link. Here's an example:
HP Pavillion laptop manual
This is probably not yours but would be available by plugging in the model # into the correct search area.
I bought a very nice HP Pavillion Entertainment Laptop 2+ years ago at what seemed to me a very nice price at a reputable retailer. It is possible that it was a store demo which had been reconditioned by HP or their agent in Canada. It had double the number of external connections, and lots of features I could see I would be using in the future, plus 4 gigs of RAM and a 500 gig HDD, and a BluRay player installed (which will be the source of a forthcoming question, eventually, since it is no longer functioning).
Trouble was, they said they couldn't find the box, which meant, no manual, and no whatever else would have been in the box.
It offers the Lock aperture, but no Locking device. This hasn't been a problem, but I'd like to have it, just in case. Any info?
