Spilled Water On Laptop

About 8 hours ago I spilled some water on the keyboard portion of my HP laptop. I quickly cleaned it off with a towel and a sham wow to suck up most of the water. I then unplugged it and removed the battery. It turns on and the fan starts going, then when the fan begins to pick up speed it shuts off. It seems to be able to last longer. I had this problem in the summer when I didn't even spill anything on it. I'm just curious to see what I should do. Should I take it apart and clean everything. If it doesn't work on Monday, I'll take it to a repair shop...how much would it cost and would they be able to fix it?

Thanks for any help guys.
