Linux 노트북을 뚜껑을 연 채로 몇 분 동안 배터리 전원으로 실행한 다음 "절전" 상태로 전환합니다(시스템 로그에 따르면). 이것이 최대 절전 모드와 같은 의미라고 가정합니까?
하지만 내 노트북은 어떤 이유에서든 절전/최대 절전 모드에서 다시 시작되지 않으므로 처음부터 부팅만 되고 저장되지 않은 작업이 모두 손실됩니다(다행히 저장하지 않은 작업이 없습니다).
KDE 시스템 설정에 가서 이것을 구성하려고 했지만 (KDE에서) 최대 절전 모드로 구성된 유일한 시간은 배터리 충전이 "중요"하고 배터리 충전이 5% 이하로 구성되었을 때뿐입니다. 하지만 배터리 충전량은 5%도 채 되지 않습니다.
내가 달리면
journalctl -x --since="2016-06-19 08:00:00" --until="2016-06-19 08:15:00"
그때 무슨 일이 일어났는지 이해하려면 별로 볼 것이 없습니다.

노트북이 절전 모드로 전환되는 원인을 어떻게 알 수 있나요?
