PC wakes immediately from sleep...

Hi:

Here are the log details (if I'm reading it right, it's my Comcast XFinity router. I've tried unplugging the Ethernet cable, and it says it can't detect wireless networks. Could the constant wake/sleep have killed my wireless network card?)

Hi-

I tried to follow prompt one, but this is the screen I have (attached):

I had the same problem. Simple fix here. Went into Device Manager and edited Power Management for the KEYBOARD and the MOUSE, unchecked Allow the device to wake the computer. Fixed.

Hope this helps,

It did. Thank you! It was the network card causing the problem. I recently add a WIFI extender (for a Blu-ray player) to the system so I suspected that was somehow related to the issue since sleep mode previously worked.

I believe this was also the cause of intermittent sleep failures before the extender was added. I never nailed it down but I believe sleep would fail when the blu-ray device was powered up. With the extender powered on 24-7 it became much more noticeable. I just didn't make the connection before - no pun intended.
