Well my iMac just died. =*(
I've only had it for about 2 1/2 months (paid $1600!) and probably only used it like 15 times because I use my Macbook Pro more since I move around the house all the time. I was using the iMac sunday night for like 2 hrs, shut it down like normal and went to bed. Last night I decided to watch some old school family movies and hit the power button on the iMac.....I get no response. For the next 30 mins I try different outlets, press the power button in every which way the button can be pressed, use google for some help....but still no response.
First Apple product that has failed me.
I blame Tim Cook.
I was unaware the power that button could be pressed more than one way. Seriously though your computer is under warranty by Apple. Call them and get it fixed or gat a new one.
