Well, stranger things have happened.
I would suggest you find the driest spot in the house, not near water or stairwells, and leave it there for a few days and try it again. It would also be helpful if you placed on something absorbent such as paper towels to absorb any moisture leaking out from it's vents and such.
If you want to go a step further, you can remove the battery and hard drive covers, as well as RAM sticks and the hard drive itself. Leave those covers off and let the laptop dry out.
While it's drying out, you can take the hard drive and plug it into another computer's usb port using a SATA-TO-USB adapter which costs about $20 US and get your data off of it and copy onto a usb flash drive or external hard drive. Here's the link for it:

Also, you can test your hard drive by accessing it on the other computer.
If the laptop boots with the tested hard drive, it may be ok or partially ok depending on whether you can see the display or not. If that fails, you see lights and such, you can try an external vga monitor or hdmi tv connection and see if the display shows up there.. If it doesn't, your video chip could be fried or the Mobo itself.
If all that fails, you're looking at a very expensive repair to replace multiple components, replacing the laptop would be best. If you happen to have a premium warranty on the laptop, they may have drop coverage. Might be worth checking your warranty policy.
Good luck,
