[QUOTE="benorubin, post: 279808, member: 19271"] I had this problem very recently and had a case opened with Apple. My computer would either not go to sleep completely (screen would go off) or when it did try to go to sleep, it would wake back up and give the Restart Error Message. On the second attempt, it was determined that my Belkin 7-port USB hub was the cause the problem. Sure enough, with the hub disconnected the computer would go to sleep and wake up with no problems. As soon as I reconnected the hub, the problem returned. I just got back home today, turned on my iMac and there was a new firmware update waiting for me to resolve a sleep and power issue. Coinsidence??? Anyone got a good recommendation on a USB hub for an iMac? [/QUOTE]
