노트북이 정지되는 이유를 알아내는 방법은 무엇입니까?

새 노트북을 가지고 있는데 계속 멈춥니다.

충돌과 관련된 상황이나 응용 프로그램을 지정할 수 없습니다. 사고 원인을 알고 싶습니다. 충돌이 발생했을 때의 모습과 시스템 로그에서 볼 수 있는 내용을 설명하겠습니다. 이유를 알아내기 위해 진행 방법을 알려주셨으면 합니다.

충돌했을 때의 모습

재부팅 후 1시간 이내에 정지되는 경우도 있고, 이틀 내에 정지되는 경우도 있습니다. 예를 들어 가장 최근에 정지가 발생했을 때 재부팅한 후 브라우저 및 터미널과 같은 일부 일반 응용 프로그램을 실행하고 한 시간 동안 그대로 두었다가 다시 돌아왔을 때 어떤 콘텐츠에도 응답하지 않는 것을 발견했습니다. . Alt+Ctl+F1을 누를 수도 없습니다. 이 시점에서 내가 할 수 있는 유일한 일은 전원이 꺼질 때까지 전원 버튼을 누르고 있는 것입니다.

동결이 발생하면 일반적으로 노트북이 예상보다 약간 따뜻하다는 것을 알게 됩니다. 바로 재부팅하고 확인해 보면 sensors70도 안팎의 온도를 볼 수 있는데, 이는 극단적인 수준은 아니지만 정상 작동 온도(50도 안팎)보다 훨씬 높은 수준이다.

시스템 로그

/var/log/syslog를 확인했는데 이것이 충돌이 발생하기 전에 찾은 최신 로그 줄입니다. chrash1:
