I am running a dual boot Ubuntu/Windows 10 on a Lenovo t460p. In order to resolve hdd issues between the operating systems I disabled hibernate in Windows:
powercfg /h off
Since I did this change (confirmed as when I enable hibernate, all works as expected), Windows doesn't shutdown anymore, but always restarts when I hit the shutdown button. It is the second clean install I did and the issue is definitely caused by switching off hibernate. I can't find any restart problems that are related to fast startup settings and hope somebody can point in the right direction.
Thanks!
powercfgcommand. You can simply turn it off within advanced power options – Run5k Apr 23 '17 at 11:40powercfg /h onand just disabled fast startup in power settings. – tworabbits Apr 24 '17 at 09:27
