Ubuntu 16.04 внезапно выключается после отключения зарядного устройства

У меня есть Dell Inspiron 7560, который я купил совсем недавно. Я загрузил двойным образом Помощник Windows и Ubuntu 16.04 на нем.

Ubuntu внезапно выключается после нескольких секунд отключения зарядного устройства (это не происходит никакое другое время). Ноутбук является новым и так является батареей, таким образом, я не вижу оснований для этого возникновения.

Вот вывод grep -i temp /var/log/syslog* для справки.
