PC will not stay in sleep mode.

I have this problem where my desktop PC (8.1) won't stay asleep. Without moving the mouse or hitting any keys it just starts itself back up. It used to be OK and then I noticed it just wasn't staying in sleep mode any longer.

Would like to get this sorted out...... help appreciated.

after one of those wakes up try running in cmd:
powercfg /lastwake

may give a hint to what is waking it

Task or Network connection causing it. Run in the Command as an administrator, wha is posted above, and then copy and paste the results.

Sorry for the delay..... I was unavailable for a while.
From this screen shot it appears as though a USB Hub caused it.

[h=4]Warnings[/h] CPU Utilization:Analysis Error
Analysis was partially unsuccessful. Some results are available, but they may be incomplete.



CPU Utilizationrocessor utilization is moderate
The average processor utilization during the trace was moderate. The system will consume less power when the average processor utilization is very low. Review processor utilization for individual processes to determine which applications and services contribute the most to total processor utilization.



[h=4]Information[/h] Platform Timer Resolutionlatform Timer Resolution
The default platform timer resolution is 15.6ms (15625000ns) and should be used whenever the system is idle. If the timer resolution is increased, processor power management technologies may not be effective. The timer resolution may be increased due to multimedia playback or graphical animations.

Battery:Analysis Success
Analysis was successful. No energy efficiency problems were found. No information was returned.



Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.



Platform Power Management Capabilities:Connected Standby Support
Connected standby allows the computer to enter a low-power mode in which it is always on and connected. If supported, connected standby is used instead of system sleep states.

I was getting some help with this problem but since I posted the log etc. nothing has been posted since. Would appreciate what help I can get.... Thank You.

That is odd that the Realtek driver is causing it to wake up. You do not keep a headset or have a microphone plugged in do you? The other is if you have it connected via HDMI or DVI to a Flat Screen, that can also cause the behavior.

I don't use HDMI but I do have a flat screen monitor (S24D300) and yes I do have a headset mic included that is always been plugged in even before this problem started.
Of coarse, I will do checks with any recommendations that you have.... Thank You !!

I unplugged the headset and manually put the machine to sleep. It lasted for 2 minutes and woke up.
