Windows 10 won't go to sleep after recent fall update

For you or others that may have this problem I found that updating the Intel rapid storage fixed the issue.  Intel has a nice tool for updating all their drivers in their support section. Simple download it and it will tell you what needs an update.  Hope it helps anyone

Also not that device manager and driver updates did not find the issue or resolve it. Only going to the Intel page.

It has to be the latest Windows 10 updates. My New Cyber Monday HP i7 Windows 10 Home computer was working fine until about a month or so ago then all of a sudden it wouldn't go into sleep mode. My laptop, which I hadn't used in a while, was and is sleeping just fine. I finally did all of the windows 10 updates and now it is not entering sleep mode either. So I must assume that something in the updates is making this happen. Actually I feel better now because I have tried almost everything, even having an HP tech access my computer for almost 2 hours. His only final suggestion was to restore like new or reinstall Windows 10, both of which I didn't want to do. So until MS comes out with a fix I guess I am stuck with putting it to sleep manually. Come on MS, FIX THE PROBLEM!!!

if computer wakes up immediately, then check mouse and keyboard properties>power management and disable them from waking the computer,

I had this issue since sometime in the fall, and I just solved it this morning. I had tried almost everything in this help thread and others online, but nothing worked. Two things seemed to solve the issue for me.

1. Disable allowing Cortana to respond to "Hey Cortana" and disabling Cortana when my device is locked. These options can both be found in Settings -> Cortana -> Talk to Cortana
2. Under Settings -> Personalization -> Lock Screen, either choose an option that is not "Slideshow" for the Background, or make sure that the option "When my PC is inactive, show lock screen instead of turning off the screen" is set to "Off" in the "Advanced slideshow settings" section. I actually just ended up changing the Background option to Windows Spotlight, so that might also be a solution.

I'm not sure if all of these things together fixed the problem or just one of them, but now that my PC is back to sleeping normally, I'm going to leave everything as it is. With regard to #1, I guess this isn't a great option for Cortana users, but perhaps the Cortana process is part of what is preventing the PC from sleeping?

Hope this helps anyone experiencing this frustrating issue who, like me, exhausted all of the recommended solutions and none of them worked.

Cheers.
