Is that what is happening with the XPS line? My XPS 13 9333 goes to "sleep" but the backlight and the fan stay on, and the only way to revive it is to do a hard reset. And that's on latest windows 10.

Yes. You must either cook and inject your own ACPI table (taking inspiration from a similar model to save you time), or go with S0 only using a kernel patch.

I have done some bios and acpi code before on coreboot. It is tough, lots of work and no guaranteed results if you don't have access to the specs (NDA)

Anyway I really don't recommend you do that unless you have experience, documentation and time.
