Spent hours on Google trying to figure this out, but alas, I've still yet to fix it. Maybe someone here has some ideas? Essentially my workstation will no longer stay in a C3 sleep state and it's quite frustrating. It will turn back on a couple seconds after entering sleep. I'm on Windows 10 Pro 1803 (build 17134.619 if it matters).
I made a recent hardware change of swapping some drives out. I went from a 1TB PM961 + 1TB 860 EVO to a ~4TB PM983. I can't see how that would affect sleep mode since I restored straight from my Veeam backup taken immediately prior to swapping the drives. Only other thing I did around that was run some Windows updates that I had been deferring for a couple weeks.
When trying to track down the culprit, powercfg always shows the following right after my computer wakes back up, but it will soon disappear. I've not been able to track down what device that might actually be referring to. I know it is not a USB device as unplugging everything makes no difference (not that I've changed anything there).
My power plan has wake timers disabled and there's nothing there that has changed anyway. Other stuff under powercfg isn't particularly helpful unfortunately:
Anyone have any ideas as to why sleep mode might have stopped working for me? I can list the rest of my hardware specs if that would be helpful.
