There was a black out in my area yesterday. My iMac was left on overnight, so when i went to check on my Mac it was off. Pressing the power button, you can hear the initial harddrive spin, but then silence! Nothing shows up on screen! I tried unplugging it frm th wall for a while and pluggin it back in and pressin the power button to the same results. My baby ain't turnin on no more!! Is there still any hope for her?
