Some keyboard characters do not work!

''Hey Everyone

I bought my Acer S7 from Iraq and i am now in the U.S.

I accidentally spilled a small amount of water on my computer's keyboard and i left it tuned on and plugged in. At first the computer started to write by itself random characters, but then it stopped from typing by itself and some characters of the keyboard started to stop working. Some of them work but the others don't, i hope that someone could help me in solving this problem because i really need my computer's keyboard to work normal.

Would lifting the battery and putting it down help in making the keys work back again although it is not a numlock or sticky keys? '''

Could some one help me quickly please
