Hibernation problems are most likely caused by a OS/BIOS problem and not a motherboard hardware problem. To the motherboard hardware, Hibernation (Suspend to Disk or ACPI S4) looks just like the system is off (Soft Off or ACPI S5).
The first step in solving Hibernation issues would be to make sure you have the latest BIOS from the motherboard manufacturer.
If an updated BIOS doesn't work try the following from the command line as Administrator (from TechNet):
- powercfg –lastwake
- powercfg –devicequery wake_armed
- If any devices are shown, go into their Properties in the Device Manager, click on the Power Management tab and uncheck Allow this device to wake the computer.
Try to disable Windows Defender automatic updates or any automatic updates you know could be causing the system to wake from Hibernation.
Check Windows Update settings to make sure that isn't causing the system to wake. Turn them off or set automatic update to a time during the day.
