我认为我遇到了一个奇怪的问题。我在笔记本电脑上使用 Ubuntu 21.10。这台笔记本电脑配置了 Windows 10 双启动。它通常运行正常。
然后我重新启动它以进入 Windows，但重新启动后，连接到笔记本电脑的 USB 键盘和 USB 鼠标没有响应（以太网工作正常）。然后我尝试重新启动笔记本电脑以进入 Ubuntu 来调查问题，但 PC 不会重新启动！它停留在黑屏上。我按下按钮强制关闭它，然后重新启动计算机到 Ubuntu。仍然没有 USB 设备工作，我在终端中输入 lsusb，我得到了一个空输出（与 sudo 中的结果相同）。dmesg 返回给我这个：

如果您需要更多信息，我会将其添加到此帖子中。
总结一下：根本没有 USB（可能没有电源？）而且我无法重新启动或停止计算机，它会在黑屏上停止。我在 Windows 10 和 Ubuntu 21.10 上遇到了这些问题。
解释得更清楚一点：我可以毫无问题地启动任何操作系统。当我尝试使用操作系统关闭或重新启动计算机时，它会启动其程序，当它应该关闭时，它会卡在黑屏上。重新启动过程中也是一样。我发现的唯一解决方案是按住电源按钮直到电源关闭，然后再打开。而且我的 USB 端口不工作，就像它们根本不存在一样。
