有时，当盖子关闭时，计算机不会自动挂起。发生这种情况时，重新关闭盖子不会使其暂停，直到下次重新启动。重新启动后，自动挂起再次起作用。一段时间后，它再次停止工作，我无法确定是什么将状态从可挂起更改为不可挂起。
在不可挂起状态下，“sudo pm-suspend”和“sudo systemctl suspend”不会使其保持挂起状态。
我运行的是带有 Arch 64 位的 Lenovo X220。
我应该做什么/尝试让它按预期工作？
编辑：添加了journalctl输出：
日志ctl-xn

我的会暂停但立即恢复。对我来说，解决方法是禁用 ( d) LAN 唤醒：
$ sudo ethtool -s eno1 wol d
$ sudo ethtool eno1 | grep Wake-on
Supports Wake-on: pumbg
Wake-on: d
