Computer Keeps Waking Up During Hibernation

Hi all you at TenForums. I signed up so I could find a solution to a problem I have been experiencing with my Windows 10 system.

Recently, I've taken to Hibernating instead of Shutting Down or Sleeping for long periods of time (this is partly because of how the electronics work in my room - I don't want to lose all my data in case a member of the family accidentally turns a switch off which means that the entire electrical current on my floor is cut off).

Anyway, I've tried hibernating my computer two times. Once, I left my computer to hibernate, and I come back again to find that it was ON. And just now, the computer came back on again after I left it to hibernate for the night...

I have tried searching online (and indeed found some posts on this forum which explore the issue), but the common problem of Automatic Maintenance may not be the answer in this case, because:

1. It turns back on again after a short period of time. I didn't measure the time exactly, but I'd say it was about quarter of an hour to half an hour (I can only assume this happened the first time, what with me not being in the room).
2. I followed the steps to reconfigure my "AM" setting on a tutorial on this site, and found that my time was 2AM - this was not the time of either instance of my system waking up (though I have heard AM happening spontaneously, no matter the time, and my "wake the system up" setting was checked...).

Could it be a program on my system, or is there something wrong with the OS? Will test again tonight, and if my system does not wake up, then I will mark the topic as solved.

Thanks for your time

Seems not to have woken up by 20-hours time, so I'm going to assume unchecking the "wake the system up" setting did the trick.
