So it is technically impossible with Microsoft’s software?

Surely Microsoft has the resources to coordinate hardware and software with Dell/HP/Lenovo on making at least 1 reliable line of laptops where you can close the lid and reliably expect it to instantly sleep and not randomly wake up.

I bet Microsoft would like that - they tried and then after it didn't work out for 2 decades of laptops they started making their own hardware. The 3rd party vendors don't care too much to change the ways they work - they juggle the hardware they put into the laptops all the time, one model-year can have over 100 variants (some Lenovo models go into thousands). Apple has few standard components shared across all products and that's it.
