    Hi,
    I spilled a very small amount of water on my macbook (model 7,1 no removable battery) and I let it dry out (For a week!). It now won't boot (or turn on in any way) and when I plug in the magsafe no light comes on. Which leads me to believe (hope) it's just the battery that's at fault. So I unplugged the battery and plugged in the magsafe. This time it went green. (still wouldn't turn on. should it??) I then plugged the battery back in, with the magsafe in and green, and the light turned orange so I left it until it turned green but it still won't boot.
    Now I'm going to bring it into apple on Monday but I was just wondering if anyone has an idea whats wrong? (Could it just be a dead battery?) And is there a way of booting it with the battery plugged out?
    Also the magsafe light still does not turn on when it is plugged into the macbook whilst the battery is connected.

    Also any idea of what will happen when I bring it to apple? (It's way out of warranty)
    What should I say and will they charge me just to tell me what's wrong?

    Thanks

    Inside the case there little markers that change colour when they get damp. It would be highly likely that on your macbook these markers will tell the apple specialist EXACTLY the problem.

    A thousand people here can tell you whats wrong for free. Change the logic board.

    Does the Macbook boot up with the battery removed and the magsafe charger connected. If so then it could be an issue with the Dc in board or charging circuit. In any case the logic board should be immediately removed from the casing and cleaned properly with isopropyl, and then reassembled before attempting to turn it on for the first time. there may be some corrosion on the logic board caused by the spill, so this would be the best thing to do before trying out anything else.

    Cheers.

    No the macbook doesn't turn on at all. Although I haven't removed the battery only unplugged it from the logic board.
    Should the macbook boot with the battery plugged out and the magsafe in? (For some reason after an hour of googling I still do not know the answer to this.)
    I did clean one side of the board but didn't want to take apart the rest although I will try it if it has any hope.

    Yes it will boot with the battery disconnected and the magsafe charger attached and powered on if everything else is ok. I'd definitely recommend removing the logic board from the casing, to clean both sides of the logic board if possible.
