my dog knocked a cup of ice/water onto my Macbook, I did the immediate shut off and took it apart and dried it all, waited a few days and it came on but the airport didn't work. I ordered a new airport card, installed it and now the computer will not power on at all. I really don't think its the logicboard, but I don't know what else to check/double check. I get literally NO lights, sounds ANYTHING when attempting to turn the thing on, tried the typical resets, battery, no battery, etc... nothing. The only thing that works is the battery tester button on the left hand side of the machine. If anyone has ANY help to offer as far as what to maybe check, please let me know. I'd hate to have a totalled computer that I still owe 400 dollars on.... ARGH.
