Yesterday I was riding my bike around town and had my laptop in my backpack. It's started raining all of a sudden and me and my bag got a little wet. When I got to where I was going I opened my mid-2012 13" MacBook Pro, which I just got back in January. Since it was in sleep mode so it just came on as soon as I opened it. I noticed that there was maybe a teaspoon of water sitting in there some up on the screen and some sitting on the keyboard. Water somehow went through my backpack and got in between the screen and keyboard. I immediate shut it off by holding down the power button and turned it upside down with the screen open and propped it up on my water bottle so the keyboard was facing straight down and wiped off the water on the screen and keyboard with a cloth. In trying to do this I accidentally hit the power button and the screen came on and started to boot up. I immediately turned it off again by holding down the power button. When I had it upside down and cleaned off, no other water dripped down from behind the keyboard. I did some research on my phone and called around a bit and based on what a third party mac techican said I went home borrowed the right size screw driver and opened the botttom case and very carefully unplugged the battery. I did not notice any moisture in the parts I could see. Then I put the MacBook in a large plasitc container upside down with the back case off and the keyboard facing straight down and the screen open. I spread about a half pound of a desiccant called DRIERITE which is made out of ANHYDROUS CALCIUM SULFATE on the bottom of the plastic container not touching the computer and sealed up the top with plastic wrap. I was planning to leave it in there for a couple days, maybe longer, hoping that the desiccant will help any water that maybe in there dry up ASAP. Again not sure if any water made it down in between the keys, but there is a good chance that some might have. How hard is it for water to get through the keys to the good parts and start ruining things? Is there any kind of barrier stopping it? Not sure what I should do now and if I've done the right thing so far? Haven't told Apple yet what happened, didn't know if they would immediately flag my computer as water damaged and void my warranty even if no water made it through the keys.
