Stupid mistake eMac won't power on! HEEELLLPPP!

Hey everyone, well I made a very stupid mistake today by taking the shell off my eMac to clean it and now the computer won't power on! I know this was incredibly stupid of me and I really have no idea why I did it. I also tried powering it on with old usb keyboard with the power button on and no luck. It is warrantied under applecare. Any one have any suggestions??? Should I take it in to get looked at and lie?? I don't know what to do Im going crazy??!! plz help

Problem solved: I forgot to hook up the wire to the Power Button lol.
