Investigating the issue of my work laptop sometimes rebooting when I try to use Sleep for travelling it. This is because Windows took the "Hybernate" option away, however I learned that it is possible to manually call the hyberbnate function from a CMD window using "shutdown /h". The rebooting while sleeping seems most likely to be due to damage to the laptop's motherboard.
This is an article titled with the exact problem that I was trying to solve. It had pretty much the same solutions as a lot of other related pages, which were to fiddle with power settings most of which I couldn't touch due to the group policy settings on my laptop: https://www.guidingtech.com/fix-windows-10-shuts-down-instead-sleep-hibernating/
I was unable to get around the group policies to try to turn off "fast startup". Here are a few searches that I tried on the topic. The hints, while unsuccessful, were interesting and I'd like to learn more:
