Windows 10: Win10 Pro 64bit 10.0.18363 woke from hibernation - what caused it?

I'd need to determine the reason for a PC power on. Presumably no person was close to this PC at the time.


What started the PC from hibernation?

What has the power to poweron the PC from hibernation?


Here is the data from

powercfg /sleepstudy


From the image:

I used the PC until 12:49 and put it in hibernation.

At 17:09 the PC started.
Since the back fan was disconnected the bootup waited at a fan error message waiting for press F1.
At 18:33 F1 was pressed and boot continued to Windows.

comments:
I left the house at 16:56 verified from other logs.
17:09 is from BIOS log & windows sleep study.

I have verified that HW clock can hold correct time without internet access.

There is nothing in the logs preceeding 17:09 like windows update reboots or the like.


WOL is OFF in BIOS but on in device manager NIC settings without need for magic package.

If there are no timers with the power to wake the PC the most likely reason for poweron from hibernation is physical access?

Its a DELL Precision T1700.

Windows 10 Pro 64bit Hibernate does not work as per power plan

I recently purchased and installed Win10 Pro 64bit. It works very well except for the Hibernate/Sleep options. I enabled Hibernate and set the size of the hiberfil.sys to 100%. (powercfg /h size 100).

I have 32g of RAM and over 100Gb of space on my system SSD. When I manually put the unit into hibernate, it powers down and then powers up on its own after a time. I have disabled all wake timers and the fast start option. When I installed Win10 Pro, it
was a clean installation on a freshly partitioned and formatted SSD.

I also updated my motherboard drivers to reflect Win 10 Pro 64bit. I have a Gigabyte with the Intel Z97 chipset.

Any help would be greatly appreciated.

In compatibility mode there are only 2 OS ,Win7 and Win8.
