ult*_*oad 5 shutdown acpi suspend power-management 16.04
昨天我注意到当我重新启动笔记本电脑时，它不会。计算机是全新的戴尔 XPS 13 9350。在调查了一些事情后，我注意到只有在我让计算机进入挂起模式后才会发生（不关闭），无论是通过关闭盖子还是手动挂起它。我做了一个dmesg，发现在启动和挂起或唤醒被触发后有一些 ACPI 错误。
这是启动时的一条消息，似乎重复了几次。

这是挂起或唤醒过程中的消息。

我发现的一些事情已经让我更新了我的 BIOS，但我的 BIOS 已经更新到了我上周更新的最新版本。任何帮助将不胜感激。如果需要，我可以提供更多信息。
