Laptop screen won't start up

my laptop, Hp laptop 2000-2b09wm, had gotten wet nothing major. It was working just fine I turned it off after I wiped it and put it on the side. The next day I go to use it the screen won't turn on. I unplugged the charger and took out the battery. Then tried holding the power button for a minute. I plugged in the charger only then pressed the power button I can see my wifi button light up but couldn't hear the fans or computer start up. Why isn't the display screen working please help me.
