Oh. Well, take it off again, if you can take off the hard disk (it's usually very easy, if I remember well in HPs is located just under the touchpad). If you cannot or don't want, leave it like that, if you can remove any other part (the cd-drive, for instance) remove it, move the laptop to make sure there is not any liquid left (probably there isn't but, just in case) and try again after many hours, or better tomorrow.
If it still doesn't function, it's probably useless. Sorry
