Sometimes there's enough time to enter username and password but system goes to sleep every time after a few seconds. The system can be woken up and used after this happens but it will not let me shutdown later. The problem is just present in docked situation starting with closed lid using systemd a init system. If notebook is used in non-docked situation with open lid and systemd the problem does not occur. Workaround: A switch back to upstart as init system resolves the issue.
