Change the option to “Never” for when the laptop is plugged in and/or on battery.
Note: I’ve seen people report that this issue has also been fixed by looking at drivers and such, but this worked for me, so maybe give it a shot. After applying the fix below my macbook stayed in sleep mode after closing the lid for over 8 hours.
Problem: Your power settings are configured to allow for windows to go to hibernate after a specified time. Issue: You have a MacBook with Windows 10 and instead of staying in “sleep” when you close the lid, it shuts down.
