I’ve always had issues with hibernate. Back in the XP days, weird stuff would happen so I eventually quit using it. These days, Windows doesn’t even show the option unless you do some magic. Wouldn’t be too terribly surprised if they phase it out altogether by W14
How do you turn the system back on in sleep mode? Press the power button, I take it? Or did you turn it off for hibernate?
While you’re messing around in the UEFI settings, you may want to turn on the virtualization features to improve performance in stuff like DOSBox. 🙂
