HP Recommended
Product: HP Z820 Base Model Workstation
Operating System: Microsoft Windows 10 (64-bit)

I'm trying to set up Hibernation so that I can hibernate after timeout at night to conserve energy. My backup SW is capable of waking the machine to run backups. Also, I have BIOS Device Options S5 Wake-on-LAN enabled so I can remotely power on the PC using remote mgmt SW. I can remotely Power On the PC using WOL. However, with After Power Loss set to Previous State in Adv Power Options in BIOS, when I choose Start > Power > Hibernate, the machine goes into hibernation (clearly saving the state to disk), and shuts off. But, after a few minutes the machine powers back on by itself, as if the hibernation was a "Power Loss". Also, when it does reboot from this state, I get an error about Stopcode Violation and it automatically reboots successfully.

 

On prior tests, if I set After Power Loss to OFF, and hibernate, the machine will remain off. I would like to have both options, i.e., to have hibernate remain OFF when used (either manually, or via UPS SW), and have the machine come back on if it was ON and power was interrupted without a proper shutdown.

 

Is this possible? Are there other settings I'm missing?

Other settings:
Fast Boot = Off

LAN = WOL

Win Adv Power Options set appropriately.
