You're confusing sleep with hibernation.
Power Nap is just fancy name for scheduled wakeups; it was supposed to be more but my understanding is that this never really materialized.
I'd want hibernation but it's not offered in most laptops any more, to my knowledge.
I might be confused on the name they chose to market never sleeping (never do full suspend to RAM with CPU shutdown except on special circumstances), as it was announced with Power Nap as the front facing feature.
Hibernation is still 100% an option on Windows. You can even set it to hibernate when you close a laptop's lid
It's part of the OS but the option can be removed by the OEM. I still haven't found a way to get it on an ASUS laptop, same for Surface Pro.
From MS's doc:
> This option was designed for laptops and might not be available for all PCs. (For example, PCs with InstantGo don't have the hibernate option.)
