Ubuntu 12.04LTS 中挂起状态意外唤醒

我在笔记本电脑上安装了 Ubuntu 12.04.3。将系统置于挂起状态几分钟后，它会自动唤醒。我的系统上安装了 tlp。我的笔记本电脑上还连接了 USB 键盘和鼠标。

内容/proc/acpi/wakeup如下：-

关于如何纠正这个问题，有什么建议吗？

答案1

您是否尝试过拔掉键盘和鼠标。鼠标的细微移动可能会触发唤醒。

附注：您能发布lspci终端的结果吗？当您从两个输出连接 pci 代码时，它可能会显示哪些设备有可能“唤醒”笔记本电脑。

编辑：我发现大多数可以唤醒计算机的设备都是通过 USB 连接的。如果您不使用 USB 连接的软件从挂起状态唤醒，您可以尝试禁用这些设备。

您可以使用sudo sh -c "echo **** > /proc/acpi/wakeup"命令禁用（或启用）唤醒文件中的内容。****应将其替换为您要从唤醒文件中启用/禁用的设备（例如 EHC2 或 KBD0）。

请告诉我这是否有效，以便我可以寻找其他解决方案。
