  1. I have an issue where my PC keeps waking from sleep. I have checked the eventlogs and it seems to the be the HD Audio Device that wakes the PC. The PC is a Windows 7 Ultumate 64-Bit edition running on a notebook with no domain, i.e. a normal home PC.


    I ran powercfg.exe and got the same responce.


    powercfg -LASTWAKE
    Wake History Count - 1
    Wake History [0]
     Wake Source Count - 1
     Wake Source [0]
    Type: Device
    Instance Path: PCI\VEN_8086&DEV_293E&SUBSYS_13A31043&REV_03\3&11583659&0&D8
    Friendly Name:
    Description: High Definition Audio Controller
    Manufacturer: Microsoft


    So I started a cmd.exe with admin privileges, and then tried to disable.


    C:\Windows\system32>powercfg -DEVICEDISABLEWAKE "High Definition Audio Controlle
    You do not have permission to enable or disable device wake.


    I have tried to start the PC in Safe Mode, logonto a true admin account, still same error.
