Apple - MacBook Air attempting to shutdown after a couple of seconds of inactivity

I have the same issue with my Macbook Air after a very small amount of coffee hit the keyboard. Apple store wanted to gut for $800+. It was less then a year old and I was dropping another $800 into it. What has worked for me for the last 6 months, I pressed the eject button down and wedged a toothpick to hold it down, than cut off the excess. Everything works perfectly and since I don't use a external drive that key was unused. I also found it was the only key that didn't interfere with other functions. I would love to find a programmer who could write a script that when the key is pressed once it's on and pressed again it's off. That would be the perfect fix without spending hundreds of dollars. Any script writers??? :)

I experienced the same problem. Power-down window pops up every 10 seconds. You don't pay attention for a second, machine turns down and your work vanishes. I tried to find a way to block the power-button. Not the easiest to find. I almost gave up on it. Then I found this app. It seems to work for me.

I will probably try to replace the topcase & keyboard later when I get a chance.

Apple just released a new update a couple of days ago, its supposed to resolve issues where your MBA randomly restarts. The update affects the SMC firmware. http://support.apple.com/kb/DL1627 Everybody who's facing the same problem should install the update and give the solution a try.

Sadly the firmware update didn't work for me and now I'm stuck with my own workaround, have a look at the attached picture...

I forced the eject button to be pressed down all the time with a matchstick.

Do you guys think replacing the keyboard would resolve the issue? I'm actually thinking about doing it...!
