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.
