My computer got soaked...

I didn't even realise, I had an energy drink spilt in my bag. The soft cover of my computer got wet as well I didn't think it would affect my laptop, it wasn't much liquid for the whole bag. The following day I turned the computer and it worked for a short bit, but there was "no battery detected" statement or something of this kind. I unplugged the power cord, that is when I realised it was the beverage spill. I let the comouter to dry. I did a check - turned it on - it was working, so I switched it off. Later it didn't start at all I disassembled everything, dried, doesn't start. What can I do? It's the first time I've had trouble with my laptop, I still need this one to work, it's a bad moment for buying a new one, if there is any advice which part needs to be replaced I feel confident enough to do this...
