You probably don't have hibernation enabled, as hybrid sleep requires hibernation support to save the memory content to the hard drive.

Check if you have a file named hiberfil.sys in the root for your boot disk. If you don't have it, hibernation is not enabled.

To enable it, run the command from an elevated command prompt:

powercfg.exe /hibernate on
