Spilled Water On Laptop

I know HP laptops have a history of "overheating." But, my parents are convinced that I'm just making it up. I'm pretty sure in the summer it was just overheating, because it kept turning off when I was on my account as well...I really dont know how water could have damaged since I turned it off almost immediately and there was no smoke/sounds.

If it's not working tomorrow, off to Best Buy I go.
