정지 후 바로 일어나기

내 Debian 9 시스템은 수동 또는 자동으로 절전 모드(RAM 일시 중지)에 들어간 후 2-5초 내에 깨어납니다. 덮개를 닫거나, 전원 버튼을 사용하거나, 터미널을 통해 절전 모드를 호출하더라도 문제는 항상 발생합니다. 무엇이 문제일까요?

시스템 정보는 다음과 같습니다.

$ sudo dmidecode | grep -A3 '^System Information'
System Information
    Manufacturer: LENOVO
    Product Name: 20ET004LGE

어떤 장치가 문제를 일으키는지 확인하기 위해 각 장치를 확인한 /proc/acpi/wakeup후 를 발행하여 각 장치를 일시적으로 비활성화했지만 echo DeviceName > /proc/acpi/wakeup문제가 지속되었습니다. 바꾸기 전의 모습은 이렇습니다.

답변1

이 문제를 해결하셨는지 모르겠지만 ThinkPad T460의 Debian Buster/sid에서도 같은 일이 일어났습니다. 내 결과는 dmesg귀하의 결과와 동일하지 않지만 중요한 것은 동일하다는 것입니다.

ACPI: EC: event blocked

철사. 모든AskUbuntu에 대한 이 게시물, 다음에서 웨이크 트리거로 XHCI를 비활성화했습니다 /proc/acpi/wakeup.

$ grep enabled /proc/acpi/wakeup | cut -f 1
LID
SLPB
XHCI
$ sudo su
# echo XHCI > /proc/acpi/wakeup

이것은 나를 위해 문제를 해결했습니다. 이상하게도 이것은 컴퓨터에 USB 장치가 연결되어 있는 경우에만 의미가 있지만 저는 USB 장치가 없습니다.

편집하다:신경 쓰지 마세요. 각 줄에서 비활성화하려는 부분을 잊어버렸습니다 /proc/acpi/wakeup.

답변2

문제가 해결되었습니다. 어떻게 보면 키보드다. F 키 중 하나가 손상되어 키가 계속 입력을 보내는지 테스트하기로 결정했습니다. 그런 다음 터미널에서 키보드 입력을 테스트했습니다. 키보드를 터치하지 않으면 입력이 표시되지 않았습니다. 그래도 새 키보드를 구입하면 컴퓨터를 절전 모드로 전환할 수 있습니다. 나는 이것이 Thinkpad BIOS와 관련이 있을 수 있다고 생각합니다. OS에서 무엇을 시도하더라도 절전 모드에서 깨어날 수 있는 키보드 입력을 볼 수 없기 때문입니다.

답변3

이 문제는 이미 해결되었다는 것을 알고 있지만 제 경우에는 이 문제를 비활성화해야 했다는 사실을 공유하고 싶습니다 GPP0. 이것이 같은 문제를 겪고 있는 다른 사람들에게도 도움이 되기를 바랍니다./proc/acpi/wakeup# echo GPP0 > /proc/acpi/wakeup
