iMac not going to sleep

I have a 2010 imac with an intel quad core i7 and had the hard drive replaced a couple of weeks ago. I it seems that the machine won't go to sleep from the energy saver settings that I set -- the screen will dim, and then go dark, but I don't hear it going to sleep like I do when I put to sleep manually. I just tested it now with i min settings so I could observe it, and I don't think it did. When I manually put it to sleep and then press a button on my keyboard, I can hear it power back up before the display comes back on. This seems to have started after I had the HD replaced. Anyone out here with the some problem? I'm on Snow Leopard 10.6.8. Also, when I saved got the machine back, I used migration assistant, but I think I have have used the same account on my mac book pro -- I didn't intend to do it. I wanted to transfer the old mack hard drive with the home folder name ad everything onto the new HD. I thoughtI was doing it right, but I'm not so sure now. So I have to different machines with the same home folder name and the same password. Could that perhaps have something to do with it? just thought I'd ask.

Try a

SMC RESET

http://support.apple.com/kb/HT3964

Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.

It is the 5 second timing that initiates the reset.

It may help with the sleep problem if it doesn't help Apple's work is guaranteed for 1 year.

If the SMC reset doesn't fix it,

Got to the articel, and that didn't seem to help either. I did an smc late last week regarding some bluetooth issues (sometimes my pad loses the connection, or won't connect at all coming out of sleep), and went through some of the list. I think I'll gave to call support and see if they have any answers. Why does this alway seem to happen to me? I dread taking in my machine to the store.
