Actually, I was closing the lid which set sleep state to S1. I changed to so it would be S3, and that made some what of a difference, but the overall problem is the same: the laptop never wakes back up. After a "resume" I can no longer see the display or ping the laptop. However, waking from S3 restored USB and keyboard functionality.
