Sorry, I know this is almost a year old, but I'm having the same issue. Water was spilled on the keyboard, and it stopped turning on. I replaced the mobo, but still nothing. So, it must be the keyboard, but I want to get it turned on so that I can confirm before I throw any more money at this thing. There's no stand alone power switch underneath the key, it's actually integrated into the matrix of the keyboard. My question is, which two pins at the keyboard zif socket can I short to turn it on? I've seen it done with other models of Acer notebooks using the last two pins on the left, but that's not working for this model...
