Do the older macbook pro's like the Santa Rosa have liquid damage detection sensors? Or is just in the newer ones? A year ago I spilled a tiny amount of beer on it and only a few drops got under 2 or 3 keys. I quickly popped them off, dried the area and everything was fine. My gpu failed recently due to the whole Nvidia thing and I had to ship it off to Apple. So I was wondering if they will be able to tell there was a spill and void my apple care warranty even though the failure was not caused by this? I'm really worried because it was only a few drops and it did not leave any residue... Update: Anyway I got my computer fixed with crappy results. I posted the pics in the bottom post because I'm not sure how to delete posts.
