As some people reported sleep-related problems and also other issues with the M16, which I also encountereed on my own and fixed on my device, I decided to write this down so that everyone with these problems can fix them on their machine if they run into them.
Some of them are also just features that some people are unaware of.
These fixes mostly involve changes in Windows Power Plan and Registry. I only tested them for Windows 10 for the Zephyrus M16 2021, but I'm sure they also work for Windows 11 and also for the 2022 version.
Note: My Windows is set to German. I took the English names for the power plan settings out of the registry. They might be called different depending on language settings. The names of the registry keys themselves are unaffected by your language setting.
