I'm new to macs, I had a slight spillage behind my computer. I'm not sure if any actually went into the air fan at the back but i paniced and picked it up and tossed it around a bit. Now I can't get anything from it. There is a pulsing light on the front of the computer now. Previously the screen was black but it appeared the computer was still running. Now nothing. Its brand new..... help pls, i read about moving it while it was on and sleep mode?????
