Help! Power button not working on Inspiron 1720.

So I spilled wine on the upper right center part of my keyboard last night, and several keys ceased to function, like 7-backspace, u through \ and, most distressingly, the power button. Well, not knowing the power button didn't work anymore, I shut the computer down in the hopes of re-starting and perhaps solving the issue. But now I can't power back up.

I took the panel above the keyboard off, unscrewed the 4 top screws, and slid the keyboard itself out. I wiped everything down with a dry paper towel and used compressed air to try to dry things even more. When i put it all back together, I'm not sure what I pushed, but Dell Media Center (or something along those lines) came up. Hoping that exiting that would bring up Windows, I did so, but it just shut down again. And the power button still doesn't work.

I took it apart again and just left it apart, hoping it would dry out further, and that's where I am right now. Is there anything else I can do to try to fix this?
