I spilled coffee on my keyboard and of course it stopped working. I took it to an authorized dealer and they said there was nothing they could do, but my Mac still worked with a wireless keyboard, but that stopped working so I found you guys and ordered the part to try.
My husband but the new keyboard in following the step by step instructions and now it works perfectly!
It never hurts to try something, if it doesn't work at least you tried all your options! Never drink coffee by your keyboard!
