Не выключается ноут

[Deo]

Ubuntu 16.04, Lenovo-B50.
При выключении ноутбука процесс зависает на сообщении: "reached target Shutdown"
(в 1 из 100 попыток всё же выключается).
Да, видел много тем по этому поводу, из них что-то перепробовал, что-то побоялся (типа переустановки БИОС), что-то не понял (ввиду злоупотребления авторами спец. жаргонизмами). Темы 2-3 летней давности, так что оживлять их нет смысла, к тому же в основном они "РЕШЕНО".
Предполагаю, что тут что-то с несовместимостью ядра системы, ибо на этом компе на версиях Ubuntu 12 и 14 не работал микрофон, теперь на Ubuntu-16 заработал хотя бы внешний микрофон, но перестал выключаться ноутбук.

у меня такое было, когда игрался с энергосбережением.
Дело оказалось во включении pcie_aspm для неподдерживаемых устройств.
Вру, даже на двух буках, оба Acer
Попробуйте pcie_aspm=off к параметрам ядра добавить
Можно одноразово при загрузке дописать в grub

pcie_aspm=off

Не помогло.

У серии В50 овер 60 модификаций. Но они все на Интел. Подробнее желательно.
Проблема похоже в неработающей acpi. Выключена в УЕФИ, или ОС установлена в эмуляции БИОС, или ядро загружается с параметром acpi=off. 
reached target Shutdown - цель выключения достигнута. Вин95 на АТ ещё машинах, писала - Теперь питание компьютера можно выключить.
