I did the SMC reset for my iMac intel-based and now it won't turn on. What can I do to fix this?
iMac, Mac OS X (10.6.8)
What'd you do to it?
SMC reset is just to unplug it....
I followed this exactly:
And when I went to go turn it on it wouldn't do anything.
Well, first things first... is the power cord fully plugged into the back of the iMac (and the wall, for that matter)?
Make sure the wall outlet has power, too... I've scratched my head over stupid issues where I forgot to flip a wall switch.
If the outlet does have power, then try doing a pram zap. Command + option + P + R (hold those at startup).
If the machine is receiving power, you should be able to see some LEDs if you look through the bottom grate of the machine to the left of the RAM door.
Yes power cord is plugged in firmly both to the wall outlet and the back of the computer. The wall outlet is working fine because I tried another electrical device and it works fine.
I tried the pram zap. It still did not turn on.
I checked to see if there are LED lights on in the bottom grate and there is.
Now what?
Try holding the power button for a few seconds and see if it comes on....
Tried that several times...still won't turn on. Funny thing is it was on and working prior to the SMC reset. Reason I even did the SMC reset was because there was no output sound coming from it...either with the built in speakers, external speakers, or headphones. I read on another discussion that doing the SMC reset can fix audio issues...and now my iMac is just a paperweight...Very frustrated!
Try another SMC reset, but this way (this was the old way Apple used to recommend.)
Remove it from power. Wait a good ten, fifteen minutes, then hold in the power button for five seconds. Next connect it back to power and try it.
Tried that and it still did not work.
Thank you for your help, all. Not sure where to go from here...
