When I push the power button on the keyboard or the computer, the power light briefly comes on and then goes off. In this small time period, one can hear the very beginnings of power up, but it then just stops.

Is something wrong with the switch? Anyone know of other people with iMacs that have shown a similar problem?

No takers?

I was hoping someone would have some input before I was forced to spend money to have it looked at. I suspect something is wrong with the power supply or something along that line.

Try unplugging the machine for a few minutes (5 to 10 should do it) then plug it back in and try power on. If that doesn't work, try unplugging the machine, openning the bottom door, and push the PMU reset button (between the memory and the jack panel). Push it once, for a second, then wait 10-15 seconds, plug the machine back in and try power on.

If that doesn't work, the next step requires partially disassembling the machine and testing power flow in the unit. If you can get the service manual .pdf, follow the instructions in there. Otherwise, take it in.

Good Luck!
