我在使用新的 Debian 11 笔记本电脑时遇到问题，有时它工作正常，但有时它会在启动约 30 秒后反复进入睡眠状态。

我可以提供一些确认硬件问题或隔离配置问题的想法吗？试图筹集什么suspend.target？
答案1
您可以使用 解决该问题sudo systemctl mask suspend.target。这将阻止您的计算机不断挂起。然而，根本原因仍然存在。
达到稳定状态后，环顾四周找出是什么命令暂停。一种选择可能是电源按钮松动。通过运行确认acpi_listen从包中acpid。如果看到电源按钮事件，或者笔记本电脑盖子开关关闭，您将看到以下类型的消息：
~$ acpi_listen
button/power PBTN 00000080 00000000
button/power LNXPWRBN:00 00000080 00000001
button/lid LID open
button/lid LID close
button/lid LID open
如果它运行了一段时间没有消息，那么这不是你的问题。
如果您发现任何进程占用了大量资源，那么这些进程就值得检查。就我而言，我的粉丝声音很大，并注意到systemd-{logind,journal}使用以下命令占用了大量资源top：
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
724 root 20 0 515012 8348 6880 R 87.5 0.1 7:15.06 systemd-logind
321 root 20 0 482776 306700 304868 S 12.5 1.9 0:55.29 systemd-journal
journalctl -f将有助于隔离这些进程的原因。就我而言，这不断重复：
Aug 24 08:44:42 simswe28 systemd-logind[724]: Suspending...
Aug 24 08:44:42 simswe28 systemd-logind[724]: Unit suspend.target is masked, refusing operation.
Aug 24 08:44:42 simswe28 systemd-logind[724]: Failed to execute suspend operation: Permission denied
Aug 24 08:44:42 simswe28 systemd-logind[724]: Suspending...
Aug 24 08:44:42 simswe28 systemd-logind[724]: Unit suspend.target is masked, refusing operation.
Aug 24 08:44:42 simswe28 systemd-logind[724]: Failed to execute suspend operation: Permission denied
Aug 24 08:44:42 simswe28 systemd-logind[724]: Suspending...
Aug 24 08:44:42 simswe28 systemd-logind[724]: Unit suspend.target is masked, refusing operation.
Aug 24 08:44:42 simswe28 systemd-logind[724]: Failed to execute suspend operation: Permission denied
在这种情况下，systemd-logind正在对某些信号做出反应。您可以通过隔离和抑制信号/etc/systemd/logind.conf。
就我而言，我一次设置多个选项ignore，然后systemctl unmask suspend.target && systemctl restart systemd-logind。我发现更改HandleLidSwitch=为suspend解决ignore了问题（即使acpi_listen没有记录盖子开关事件）。
答案2
我的笔记本电脑曾经随机挂起，结果发现电池无法正常充电（充电器电缆损坏）。其他原因可能是过热（机器周围气流不足）。
