Regarding sleep: Windows still doesn’t get it right - my daughter plays Roblox on my wife’s Dell laptop, as she’s 5 she just closes the lid with the game running when she’s done. I sometimes hear the fan going before I go to bed later, because apparently a “slept” windows laptop is still merrily letting whatever game was running render 60 fps with the lid shut. Bit silly, and probably awful for her battery life
