최대 절전 모드는 항상 저에게 효과적이었습니다. 시스템 설정에서 2시간 후에 최대 절전 모드로 설정했습니다. 아침에 전원버튼으로 깨워주세요.
갑자기 작동이 멈췄습니다. 매일 아침 여전히 깨어있습니다. 메뉴에서 Suspend를 선택하려고 하면 시스템이 잠자기 상태인 것처럼 작동합니다. 즉, 키보드 조명이 꺼지고 모니터가 꺼지는 등의 현상이 발생하지만 바로 다시 돌아옵니다.

답변1
로그에 따르면 시스템이 즉시 절전 모드에서 벗어나는 이벤트를 수신한 것으로 보입니다.
새 마우스나 키보드 등 새로운 USB 장치를 사용하기 시작하셨나요?
제가 연구를 하면서 발견한 것은 깨어나서는 안 될 때 깨어나도록 신호를 보내는 장치일 가능성이 높다는 것입니다.
