my cat accidentally spilt my glass of water and some of it got onto my macbook, which was open and on. i wiped the water off and the laptop was still on and working. then suddenly the screen went black although i could still see the outlines of the windows on the screen: it was still on. i switched it off and tried turning it on again but it wouldnt turn on. a friend said i should tilt the laptop so the water could drip out and i did this, although i tried to turn it on several more times (which i later found out i really shouldnt have done!!) i'm not sure what to do now...how long should i leave it to dry? should i try turning it on again in a couple of hours? please help!
