Ok another sleep problem here, though its a bit different than the other posts. So the last couple nights that I have put my iMac into sleep mode, its been acting wonky. Ill put it into sleep mode and the screen will go out like it should, but the pulsating light won't come on, the fan seems to kick in and not turn off, and the keyboard wont work, and the mouse stays lit. There seems to be no way to kick it out of this mode, as the keyboard nor mouse does anything. Its like its stuck between being on and asleep. Only option I've found is to just hit the power button off, though I'm not sure how good it is for the machine for me to be turning it off in this wierd mode. Just to note his doesn't happen everytime, as the iMac will end up sleeping like 5 seperate times each day, and so far this has only happened once a day max. Has anyone encountered this or have any ideas?
