Enable Hibernation

Hibernation is the middle ground between putting your computer to sleep and shutting it down entirely. It saves your PC’s current state to the hard disk and shuts it down so you can resume where you left off without waiting for your PC to boot up completely. 


Disable fast startup

Fast Startup is known to cause a bunch of problems with Windows sleep, hibernation and the secure boot features. Try disabling fast startup to see if that solves the issue.
