Система начинает после завершения работы - после обновления Ubuntu от 14,04 до 16,04

Я обновил свой Kubuntu до 16,04. С тех пор затем, я не могу завершить работу своей сессии сразу. Когда я выбираю пункт меню, все идет как ожидалось сначала. Однако спустя приблизительно 5 секунд после моих 4340 HP Probook выключен, это запускается снова, как будто кнопка питания была нажата снова (и это не было).

laptop-mode-tools установка не помогла, ни действительно копала модификации настроек ("acpi=noirq"/"acpi=force"и"apm=power_off"). СЛЕД НА НАСТРОЙКЕ ЛОКАЛЬНОЙ СЕТИ в BIOS также выключен.

При изучении journalctl журнал от завершения работы и запускается, процедуры также не показали ничего подозрительного.

Я не думаю, что проблема связана с аппаратными средствами, так как это не произошло в предыдущих версиях (K) Ubuntu.

Где могла быть проблема? Что еще я проверю?
