Grrr. Spoke too soon. I got a day out of it,, but it is not sleeping again. No idea why. I'm sure a reboot would help, but this getting SO irritating.Hi,I just wanted to take a minute to thank you for this. My situation was actually a bit unique, as compared to what I had read elsewhere. My computer had absolutely no issues sleeping, but because it had been operating for well over a year, I began to see some performance issues. It's at this point I usually reinstall the OS. I was "smart enough" to have created a clean-install image so I could do this rapidly. Oddly, sleep was an issue from the get-go once the image was up and running.
srvnet was an issue, but the powercfg override was not working (I recall that fixed it in the past). Disabling IPv6 got me half-way there, as it would sleep, but only the first time. After a wakeup, it would not go back to sleep again. I happened upon this post and tried the netstop/start on the service. Shocker! It fell back to sleep on its own. I figured that was enough to try your replacement driver.
I did so, tested, and everything continued to work as expected. I then began adding items back into the mix (keyboard, mouse, background apps, foreground apps) one at a time and each time, sleep continued.
What I don't understand is why, with the same code base/install, this became a problem now, when it was not before, particularly when using the same configuration, software and hardware. I'm not sure I'll ever know, but very happy that this is finally working the way it should. Thanks again for the information and the replacement driver.
I'm happy that my solution helped you too (so far)!
Although it is very strange that the srvnet issue started only after you reinstalled the OS, it is more or less what happened to me; everything was working fine for about a year since W8.1 installation, then srvnet suddenly started to prevent the auto sleep, and that without any HW or SW changes. I think this is going to remain a mystery.
