Spilled Pom juice. Doesn’t always turn on.

This happened exactly a week ago:

In a rush to work I placed my laptop in the same bag as my breakfast containing Pom juice. I can’t remember which direction it was facing. I’m not sure if it spilled directly into the vents on the back or the vents sat in a puddle, but juice was dripping out when I held it sideways. It was still working at first, then not later the same afternoon. Next day it turned on and worked fine up until today, now it won’t turn on again.

As someone that’s never taken apart a computer before, is there something I can do or will I need to pay someone else to do it? If I knew what needed to be done I’d definitely try!
