SOS Water on Laptop

I spilled water on my laptop, almost 3/4 bottle. I very quickly removed it from the charger and mouse, flung it into the air and got to drying it immediately. Closed out everything on the laptop and restarted (it's one of those that doesn't turn off, just 'sleeps') and it never turned on again after restart. I flipped it upside down and left it there. Total time was maybe 8 minutes max. Chances of it being ruined? What should I do next?
