Microsoft had this shitty idea of "InstantGo" aka "InstantOn" aka "Modern Standby" aka "Connected Standby" (the namings alone give away whose idea it was). They think that people cannot wait the like 1 second when opening a laptop to return from suspend2ram / s3, and they think that laptops should be connected to networks all the time. What for I have no idea, they're not phones after all. So now laptops do not actually sleep anymore, at all. The merely run in a low power profile. The worst is that support for S3 got worse in many bios/uefi implementations, where either it doesn't work properly anymore or it is gone entirely :(
