Windows 10: Windows is waking up the machine from hibernation hours later...

Hello.
I usually use hibernation. But now with windows 10 sometimes when I arrive at home, the machine is on. I suspect that the auto update is trying to rebooted the system by itself... is that possible? What could be the reason?

Once I saw this happening and soon after the machine wake up appears the warning about schedule to reboot to update...

Thanks.

Transition from sleep to hibernate fails

I have a problem with my laptop not hibernating from sleep following the creators edition update.

Before the update I had my machine set to sleep after 20 minutes and hibernate after 30 minutes

For my usage this worked perfectly, if I didn't wake the machine up from sleep then

I would probably not be back for some time so would hibernate to save power.

Following the creators update my laptop would sleep fine but when it wakes to hibernate it fails and

goes back to sleep. This repeats for ever until I wake the machine.

If I manually hibernate the laptop it works fine.

I have tracked the problem down to a wake timer being set for a backup to a server running Windows Home Server 2011.

This wake timer prevents hibernating from sleep even if the wake timer is set for many hours in the future.

If I disable the task that sets this wake timer the sleep then hibernate operation works as it used to but

of course the backup never runs.

If I change the power option for wake timers to important events only the laptop works as it used to but it does not wake up

to carry out the backup.

I have carried out a number of tests and have discovered that any wake timer that is timed within 24 hours of the

attempt to go from sleep to hibernate will cause the transition to fail.

Could someone please test this as I can't believe this is how Microsoft designed it!!

 

Schedule Windows 10 Update Time

Is there a way to set Windows 10 to not wake my computer from hibernation? Due to the nature of what I do with my computer, I have to leave it running for long periods of time without going to sleep, so I have disabled the auto sleep function, and when I
stop using the computer to save power I put the computer to sleep or hibernate.

My issue is that when Windows Update determines that an update needs to be installed, it will wake my computer up from hibernate or sleep, and my computer won't go back to sleep until I get home, often 24 or more hours later. Can I schedule Windows Update
to not wake my computer from hibernation, or wait to check until I wake it? I don't mind the updates, I just need my computer to stay in hibernation when I put it there.
