Windows 10: PC wakes up to hibernate (S4 Doze to Hibernate) when it's disabled

A strange occurrence has recently been annoying me on my desktop: I usually put my computer into sleep mode rather than shutting it down, but Windows has started deciding I really want to hibernate instead. Between 1 and 10 minutes after sleeping, the computer wakes up and hibernates. It only wakes very briefly and it seems impossible to prevent it from going into hibernation, but input is nevertheless registered.

In Event Viewer the reason for the wake is the infamous "S4 Doze to Hibernate" as the Wake Reason.
By my understanding the setting governing this behaviour is the "Hibernate After" setting listed under Sleep in the settings of the current power plan. Most people seem to be able to alter this behaviour by changing this setting to a high number or to zero, disabling it. However, this setting is already zero, i.e. "Never," yet the phenomenon still occurs. I tried changing it to a very large number (999999) but the computer still wakes up. In this situation, though, it seems like the computer sometimes wakes up, attempts to hibernate and fails to do so: subsequently booting up doesn't succeed properly and the computer reboots itself.

This is pretty bizarre behaviour because it seems like it should only occur with a computer on battery power anyway. What else governs this behaviour, and how can I disable it - without also disabling some other useful feature (e.g. disabling wake timers, disabling hibernate, that kind of thing)?

(Windows 10's sleep behaviour really annoys me: the other ridiculous problem is the Windows Update task that will get re-enabled after you disable it, which wakes the computer from sleep to perform an update and can then fail to do so and never shut down again)

Windows 10 always auto steathly resumes my computor at niight, how to disable it?

Thanks for your information!

I find there is one such log which contains a line "Wake Source: S4 Doze to Hibernate".

Is it a good clue on how to fix this problem?

From searching, I set the "Hibernate after" to a very large number now..

The option to wake from sleep so that it can hibernate has two settings. One for when on batteries and one for when on the power outlet. The default setting for the one when on power outlet is Never. So in fact if it is set that way and you are using
a power outlet then your computer shouldn't have woken up for the "Wake Source: S4 Doze to Hibernate" that it listed. And you shouldn't even have changed the default 180 minutes one, because it wasn't for this purpose.

So I agree there is either a bug it waking up your computer for Sleep to Hibernation when it shouldn't or the wrong source of the wake up is being logged in the event log.

One general thought. I don't use hibernation and by default they allocate 1 or 2 to it (in a system hidden file at C:\), so I just turn it off, and that removes the file and the state from the machine. It might be worth trying turning it off and see what
happens. And if does wake again also recheck the event for its source.

Right click on the Start button: select Command Prompt (Admin)

And then enter the command:

powercfg /HIBERNATE OFF

If you want to turn it back on it is just:

powercfg /HIBERNATE ON

 

I found the solution to this, and the culprit was AMD, which saw fit to install a service, called, "AdaptiveSleepServices" which overrides a user's power settings and doesn't tell you about it or provide a visible way to disable or alter them.

If you have the same problem, disable this service and set it not to automatically start.

Note that using Driver Sweeper or whatever tool to remove the AMD drivers doesn't do anything to remove or disable this service so you have to do it separately even if you, like me, no longer have any AMD hardware in your computer!

What a bunch of highly competent and helpful guys they are over at AMD! I'm really glad they know how I want my computer to behave better than I do myself!
