在 Unity 菜单中按下“暂停”后，计算机（桌面）暂停，电源 LED 熄灭，磁盘停止。然后在不到一秒的时间内恢复。
搜索给出了这样的解决方案笔记本电脑无法挂起或休眠（无需用户交互，2-5 秒后唤醒）它们不起作用：

如果网线与计算机断开或互联网线与交换机断开，则暂停工作正常。
有到该机器的转发端口，并且 torrent 应用程序正在运行。但是，当 torrent 启动时，在登录配置文件之前暂停存在问题。
看起来有些广播消息正在通过 LAN 中断暂停。
- BIOS 中已关闭铃声唤醒功能。
- 在 BIOS 中选择 S1 或 S3 挂起状态无效。
- 我重新安装了干净的 15.10，并且没有效果。
- 这个问题在 15.04 上也存在
- 4.2.0-16、-18 内核也是如此
请指出一些需要搜索的问题。谢谢。

答案1
BIOS 有问题。在技嘉网站（MB 制造商）上找到了针对我的 MB 较新版本的修复程序。使用我的修订版的较新固件刷新 BIOS 无效。向制造商寻求支持。
问题与操作系统无关。
