I know this may sound silly, but you may try blow drying your laptop at the low setting (don't hold the dryer too close maybe 6 to 10 inches away and aim for the seams in the screen assembly) or setting up a portable fan to blow on the screen. Otherwise, I would leave the machine off, even a few days if you can stand it, until you think it is really dry and then try booting up.
