I've got a 13" MacBook Air here that someone gave me after they spilled water on the keyboard. It's been off for quite a few months so, so it's dried, and I'm looking at what works and what doesn't. What is wrong... 1.) Won't work without power cable attached. If you yank off the Magsafe, it shuts off immediately. 2.) Keyboard doesn't work, trackpad doesn't work. But, both USB ports work because you can plug in a mouse and keyboard and they work fine. 3.) Internal fans kick up to pretty much full speed immediately and stay that way. My question is, what sort of repair would you say this needs to become normal again, and is it even worth doing? I'm assuming the logic board has been at least partially damaged, and could very well be the root of all the symptoms. What do you think?
