My daughter accidentally spilled orange juice on our MBA. It powered off and after cleaning it up my wife tried switching it on (I know she shouldn't have). We let it be for about 5 days but it still won't turn on or charge. From what I've read it sounds like the it is probably a logic board issue and likely expensive to repair (the MBA is almost 3 years old so not worth the repair cost). Should i even bother taking it to the apple store and have them take a look or is it pretty hopeless and the trip would be a waste of time? Thanks.
