임의의 최대 절전 모드/절전 모드를 중지하는 방법은 무엇입니까? (우분투 데스크톱 버전 18.04)

18.04를 실행하는 Ubuntu 데스크탑, 절전 및 최대 절전 모드가 꺼지고 모니터/키보드가 연결되어 있지 않으며 현재 몇 주 동안 실행되었으며 일부 사용자 정의가 훌륭합니다.

오늘 아침에는 SSH를 통해 응답하지 않았고 서비스가 클라우드 애플리케이션과 통신하지 못했습니다.

로그에 액세스하려면 컴퓨터를 재부팅해야 합니다. 이 로그 이전에 사용자 정의 서비스는 0.5초 동안만 실행되었으므로 시스템은 여전히 ​​활성 상태였습니다. 이 무작위 절전/최대 절전 모드를 중지하는 방법에 대한 도움이 필요할 것입니다.
