I question the wisdom of "Modern Standby." When I put my laptop in sleep mode, I want it to sleep. I don't want it to be using the network, checking for updates, fetching email, etc. It can do all of those things when I wake it up.
All of the hotbagging nonsense where a laptop cooks itself in a bag seems to be caused by Windows trying to be clever and deciding there's some really important stuff it needs to do, so it wakes up the machine, does a bunch of stuff, and doesn't get back to sleep.
Windows, you're not as clever as you think you are. None of this work is urgent. Just stay asleep until I wake you up. Seriously, just don't.
"Modern Standby" is something that makes your laptop act like a phone. In my view, its only real purpose is to plausibly collect sensor data—just like a phone, or like all those "smart" speakers and "smart" TVs. The data itself has potential buyers and interested parties; it's a well-developed industry chain, and it's even subsidized by users paying for the devices themselves.
