为什么我的Windows 10笔记本电脑有时无法休眠？
Answers:
答对了！！！我似乎已通过此reddit帖子成功解决了类似问题：是否有其他人注意到他们的计算机在更新到Windows 10后不再自动进入睡眠状态？
解决步骤：
- 使用电源效率诊断报告
如Harrymc所提到的，您可以使用该powercfg -energy命令获取有关其能耗诊断的报告。结果可能表明错误，警告或其他有用信息，并存储在此处：C:\Windows\System32\energy-report.html
例如，我的摘要报告是：
Energy efficiency problems were found.
9 Errors
24 Warnings
43 Informational
See C:\WINDOWS\system32\energy-report.html for more details.

- 使用powercfg -requests
输入powercfg -requests到一个命令提示（可能必须升高）。应该告诉你什么编程使你的PC保持唤醒。对于我的报告，我得到：

决议案
覆盖编程使窗口保持清醒。使用命令
powercfg -REQUESTSOVERRIDE告诉Windows忽略使它保持清醒状态的所有内容，然后进入睡眠状态。
例如，根据我的报告，我不得不覆盖Kernel Driverand Connectifyd过程。
注意！ 您不必覆盖它，因为给定的驱动程序可能会由于使用中的PC而使PC保持唤醒状态，一个很好的例子是上述的英特尔音频驱动程序，它停止了不再活动的音频。
我的罪魁祸首是过程- Connectifyd。
尽管如此，还是要重写此命令：
powercfg -REQUESTSOVERRIDE DRIVER "The Name of Your Device" SYSTEM
powercfg -REQUESTSOVERRIDE PROCESS "The name of Process" SYSTEM
例如
powercfg -REQUESTSOVERRIDE PROCESS "\Device\HarddiskVolume4\Program Files (x86)\Connectify\Connectifyd.exe" SYSTEM
学分：Simplifyze（Reddit）；其他人是否注意到他们的计算机在更新到Windows 10后不再自动进入睡眠状态？
似乎是由于允许USB Root Hub唤醒您的PC所致。您会尝试取消选中该框以查看其是否有效吗？步骤如下：
- 在开始栏中搜索“设备管理器”。
- 打开设备管理器后，在底部附近，展开“通用串行总线控制器”
- 找到“ USB Root HUB”。可能会有不止一个。在每个USB根集线器上执行步骤4-6。
- 右键单击USB Root Hub>属性>电源管理。
- 取消选中“允许此设备唤醒计算机”
- OK-测试解决方案。如果解决方案不起作用，请尝试重新启动，然后再重新选中复选框。
让我们知道这是否有效！
抱歉，没有。请查看我编辑的帖子。

是否有相同的问题，并且没有选中根集线器的所有选项，但是仍然存在其他解决方法？

检查您的powercfg -energy报告没有发现任何异常。据报告，您的系统具有休眠功能（S4），并且没有明显的有问题的设备（尽管最好在不使用计算机或播放音乐的情况下进行安装）。
以下是一些建议，可能会有所帮助。
防止设备在设备管理器中唤醒计算机，尤其是网络适配器。您可以通过运行列出所有这些设备
powercfg -devicequery wake_armed。通过sfc / scannow检查Windows是否损坏。如果发现并纠正了问题，则不要以为已完全解决问题。
