My DH67BL used to sleep just fine with Windows 7 and 8, but won't sleep with windows 8.1. Are there any recommendations for this? There are no official Intel USB drivers for 8.1. When I run powercfg /energy I get between 7-9 warnings that my USB devices do not enter selective suspend. It claims this won't prevent my PC from sleeping, but it is the only warning that is given.
Any help on the matter is greatly appreciated as my HTPC is only "in use" for 4 hours a day and it would be nice if it slept the other 20 hours for obvious reasons. Shutting down is not an option as when it was asleep it would wake up to record a tv show then go back to sleep automatically.
I did a fresh install of windows 8.1 3 days ago and the problem persisted.
