A trick I found helped to track down no sleep issues was the (poorly documented) Windows powercfg command.

From an admin level command prompt (ie right click on the command prompt icon and select "run as administrator") execute the command

Code:

powercfg -requests

This will show what outstanding activities are preventing sleep mode. In my case, it was an audio driver, and I then had to issue a

Code:

powercfg -requestsoverride

with the correct combination of parameters to override that particular driver.

See this thread for some discussions on this.
