OK, you did something dumb. Welcome to the club. We've all run across these things...especially those of us who fix them. Heck, I've done it to my 17" MacBook Pro and my wife accidentally left her near new MacBook in about 4 inches of spilled Egg Nog at the bottom of a backpack. Anyway, enough reminiscing. Here's the scoop...you may be s-o-l, but only maybe. It was good that you packed it in rice, but unless you took it apart there is probably moisture still hanging around. And even if it has dried up there may be hard water deposits left behind that form unique and unusual circuits. Here's the general procedure for anyone who has spilled anything on their laptop...you may have done any or all of these and good on ya if so: 1) As soon as you notice the spill immediately disconnect the power cord, remove the battery. Open the laptop halfway and turn it over...like a tent...on a dry cloth. leave it there for a couple of days. Any leftover water should drain out the front edge of the keyboard...hopefully away...
You forgot the coolest part of a banana tear down. Before eating but after peeling, press your fingers, gently but firmly all around the top of the banana until the top begins to split into 3 parts lengthwise. You can then either stick your finger gently in the split and work it slowly down the length of the banana, or continue massaging the banana as you move down its length. Eventually you will be able to separate the banana into 3 long pieces. Now you can make a banana split or have 3 equal pieces to share with 2 friends. Sorry, no pics cause we ate the banana.
