几周以来，我在挂起 ThinkPad T15p 笔记本电脑时遇到了问题。两种情况：
- 合上盖子。笔记本电脑背面的红点始终亮着，从不进入“睡眠”（发光/褪色）状态。当我再次打开盖子时，我看到登录屏幕随着合上盖子的时间（或几秒钟后）闪烁。然后是黑屏，然后登录屏幕随着合上盖子的时间闪烁，然后是黑屏，……等等。我无法中断这个循环。我能实际操作是按 Ctrl+Alt+F[1-12] 并使用另一个 tty 控制台。
- 使用
systemctl suspend。这只会将我从会话中注销，然后我就会看到登录屏幕。当我登录时，我的会话确实被保存了，我可以继续工作。但在这种情况下，我从未合上盖子。
我现在将忽略第二种情况，因为这不是我的用例，而只是一次测试。这是我在 20:13:00 合上盖子时的系统日志：

当你鼓起勇气浏览所有这些内容时，你可能会发现系统似乎进入了某种 NetworkManager 循环。此外，如果我拿起笔记本电脑并将耳朵贴在底部，我就能听到咔哒声（尽管我有一个 SSD 磁盘）。
当我看到这个 NetworkManager 循环时，我尝试在暂停之前进入飞行模式，但这并没有改变任何事情。
我使用6.2.0-37-genericGnome Classic 的内核。
请帮帮我，我真的需要恢复挂起模式。
