When I close the lid my XPS 13 shuts down instead of going to sleep. Same issue when I use the power button. I've set my preferences to go to sleep when the lid is closed or pressing the power button. But the XPS 13 acts like those preferences don't take effect.
I hope someone has a procedure or update that I can run to make the machine respect the sleep preferences.
I've seen a similar post from 2014 for an Inspiron model running Windows 8. Now in 2016 most machines are probably running Windows 10. So the problem has existed in other machines and prior OS's.
