ThinkPad T450 关机后重新启动

我正在尝试调试我怀疑是硬件问题的问题。简而言之，我的 ThinkPad T450 在关机时立即重新启动，并在挂起时唤醒。

我正在运行 Ubuntu 16.04，我已禁用 proc/acpi/wakeup 中的所有内容，并将系统上每个“唤醒”文件的内容设置为“禁用”。

proc/acpi/wakeup 配置：

Device  S-state   Status   Sysfs node
LID       S4    *disabled  platform:PNP0C0D:00
SLPB      S3    *disabled  platform:PNP0C0E:00
IGBE      S4    *disabled  pci:0000:00:19.0
EXP2      S4    *disabled  pci:0000:00:1c.1
XHCI      S3    *disabled
EHC1      S3    *disabled  pci:0000:00:1d.0

问题仍然存在，以下是从挂起唤醒后的 dmesg：

我从中看不出任何明显的东西。有没有办法更详细地找出答案确切地是什么原因导致暂停唤醒？

我觉得导致系统唤醒的因素也会导致系统在关机时重新启动。我只需要找出原因。

答案1

所以这是一个迟来的答案，但我最终解决了我的问题，并想在这里写下我的解决方案，以防有人再次遇到它。

所以，总结一下，我的 ThinkPad T450 不会永久关机，每次我关闭它时，无论是通过操作系统还是电源按钮，它都会立即重新启动。

如果我长时间按住电源按钮，我会听到咔嗒声，然后笔记本电脑会完全关机，但当我尝试开机时，我会看到经典的 ThinkPad 电源 LED 闪烁。在这种状态下，要启动笔记本电脑，我必须断开 CMOS 一两分钟，然后重新连接，我才能再次启动，但无休止的关机/重启循环将重新开始。

我的解决方案

  1. 打开笔记本电脑。
  2. 在 POST/BIOS 屏幕期间按住电源按钮足够长的时间以使笔记本电脑关闭，但不要太长以触发 CMOS 需要重置的状态。
  3. 笔记本电脑关机后将立即重新启动。
  4. 在 POST/BIOS 期间再次按住电源按钮关机（但不要太久！）。
  5. 不断重复关闭笔记本电脑的这一过程，直到笔记本电脑最终保持关闭状态。希望笔记本电脑不会处于上述 CMOS 需要重置的状态。

我就是这么做的，关机大概 4 到 5 次后，它最终还是处于关闭状态。一年多以来，我都能正常启动和关机，这个问题再也没有出现过。

如果有人知道这里的问题是什么，我很想知道。
