My wife spilled a little water on her Mac Air -- MD760ll/A which we got in August 2013 (just outside of any AppleCare warranty). At first it was completely dead, but I removed the back and battery and sopped up the water and used a desiccant in a sealed box to dry it out even further.
Now it turns on, but the keyboard and trackpad don't work, however I can use the Mac with a USB keyboard/mouse.
Is the trackpad connected to the keyboard? If that's the case is there the possibility that I would only need to replace the keyboard?
