PC keeps waking up from sleep

[CHJ]

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
r"
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.

Just tossing this out there since nobody has chimed in....

 

1. Have you checked to make sure you have the most up to date drivers?

2. Did you run the POWERCFG.EXE -DEVICEQUERY WAKE_ARMED command to make sure you had the correct spelling of the device?

3. Did you check to make sure your BIOS was up to date in case you're running into some odd bug?

a guess... check the network card settings and uncehck the checkbox "Enable this device to wake up computer"
