Windows 7 wont Sleep Pt3

Hello Experts,

I received help from an expert called Kenmcse1969 in connection with my Windows 7 won't sleep when I use the Power saver to put my PC to sleep after a few hours. He gave me some commands to determine what was keeping my PC awake.

The command, powercfg -requests, results in the following:

C:\Windows\system32>powercfg -requests
DISPLAY:
None.

SYSTEM:
[DRIVER] Realtek High Definition Audio (HDAUDIO\FUNC_01&VEN_10EC&DEV_0892&SUBSYS
_1043841B&REV_1003\4&141f45d&0&0001)
An audio stream is currently in use.

AWAYMODE:
None.

I have tested this and it would appear that the Realtek driver is indeed preventing the PC from going to sleep.

Is there a way to make the Power saver kill the service so that PC can go to sleep?

Cheers

Carlton

Hi pagosche,

Are you familiar with 'powercfg -energy'?

I run the command and I got the following message:
C:\Windows\system32>powercfg -energy
Enabling tracing for 60 seconds...
Observing system behavior...
Analyzing trace data...
Analysis complete.

Energy efficiency problems were found.

4 Errors
8 Warnings
15 Informational

See C:\Windows\system32\energy-report.html for more details.

C:\Windows\system32>

I think the answer lies in the results, however I can't figure it out.

Ded9, I think the answer to the other power problems you tried to help me with lies in the results, but again I can't interpret the results to fix the problem:

I think this problem is caused by some new windows  update...can u check update history in control panel ..check whether any new updates were installed.



Ded9
Hi ded9

I checked for updates, and it would appear that a number of updates have been installed. Is there any one particular update I should be concerned about?

Cheers
Hi, pagosche

I have opened another request asking for help with power being overdrawn by processes. Do you think you're solution might resolve that issue as well?

Cheers
Do you know the exact date when this problem started...do system restore prior to that date and check.
