So, I am dog/housesitting for my inlaws. Yesterday, before I left my house I shut down my iMac as always and for the heck of it, unplugged the computer, modem, and router stopped home today, and decided to hop on the computer real quick. plugged everything back in and the computer will NOT turn on. No noise, no lights, nothing. It was fine yesterday--I shut it down, unplugged it, and plugged it back in today---now it is completely dead! So I tried other plugs and no dice. Never had any power or shutdown/starup issue before. I called Mac---but outside of driving an hour to the Apple store--it wasn't much help. The guy did say it was most likely the cord. I would be wiling to try that--as it would be a cheap option, but it looks like I may have to drive to the Apple store anyway to get a cord that fits. I also tried resetting the PMU that Apples site recommends--and nothing. Any suggestion would be great. With the holidays the thought of dropping big $$$ on computer repairs is not appealing. THANKS!
