Last night, I spilled a little bit (literally not more than 2 Tablespoons) of sugary, milky tea on the right hand side of the keyboard. I tried to dry it immediately. But soon thereafter, none of the keys worked. I turned the computer off and started it back up this morning. Now some of the keys work, and the number "8" is constantly depressed 88888888888888888888 flashes all across the screen whenever i'm ready to type. Here are my questions: 1) to provide a short term fix, how can I override the computer's own keyboard (turn it off) so i can use my external USB keyboard 2) should I try to clean it myself? 3) if I take it in to the Genius Bar (I'm under warranty) will they help me, or turn me away and comprimise my warranty? Thanks in advance.
