배터리가 삽입되는 시기를 알아야 하는 Python 스크립트를 작성 중입니다. 나는 사용한다pyudev그런 이유로.
질문:
- AC 어댑터를 연결하기만 하면 노트북을 켤 수 있습니다.
- 내가 실행하면
ls /sys/class/power_supply/BAT0응답은 다음과 같습니다.
여태까지는 그런대로 잘됐다ls: cannot access '/sys/class/power_supply/BAT0': No such file or directory - 하지만 배터리를 삽입한 다음 동일한 명령을 실행하면나는 같은 결과를 얻습니다.! 배터리를 감지하는 데 20초 정도 걸립니다.
- 나도 시도했다
역시 20초가 걸립니다.udevadm monitor -u
예상 동작: 즉시 감지될 것으로 예상합니다.
AC 어댑터를 연결했다가 분리한 후(배터리를 연결한 상태에서) 실행하면 udevadm monitor -u즉시 AC 어댑터 이벤트를 감지하고 배터리 지연 이벤트를 감지합니다.
