为什么我的 Windows 10 笔记本电脑有时无法休眠？

Question

单击“休眠”后，我的笔记本电脑会休眠，但只是有时。其他时候，屏幕会立即变黑。但随后电源按钮保持亮起，10 秒后（在我单击“休眠”后）屏幕重新出现，之前的所有内容仍然打开。在这两种情况下，我的笔记本电脑都插入了相同的 3 个 USB 设备。

禁用唤醒定时器并寻找唤醒源没有帮助：

执行此答案中的步骤并没有帮助。见这对我的最新能源report.html。

答对了！！！在这篇 reddit 帖子的帮助下，我似乎已成功排除故障并解决了类似问题：有没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？

故障排除步骤：

1. 使用能效诊断报告

正如 Harrymc 已经提到的，您可以使用该powercfg -energy命令来获取其电源使用诊断报告。结果可能指示错误、警告或其他有用信息，并存储在此处：C:\Windows\System32\energy-report.html

例如我的总结报告是：

Energy efficiency problems were found.

9 Errors
24 Warnings
43 Informational

See C:\WINDOWS\system32\energy-report.html for more details.

2. 使用 powercfg -requests

输入powercfg -requests命令提示符（可能需要提升）。应该告诉您什么程序使您的 PC保持清醒。对于我的报告，我得到了：

C:\WINDOWS\system32>powercfg -requests
DISPLAY:
None.

SYSTEM:
[PROCESS] \Device\HarddiskVolume4\Program Files (x86)\Connectify\Connectifyd.exe
[DRIVER] Intel(R) Display Audio (HDAUDIO\FUNC_01&VEN_8086&DEV_2807&SUBSYS_80860101&REV_1000\4&353e01dc&0&0001)

决议

• 覆盖保持 Windows 唤醒的编程。使用命令

  powercfg -REQUESTSOVERRIDE

  告诉窗户忽略任何让它保持清醒的东西并进入睡眠状态。

例如，根据我的报告，我不得不覆盖Kernel Driver和Connectifyd处理。

笔记！ 您不必覆盖它，因为给定的驱动程序可能会因为它正在使用而使 PC 保持唤醒状态，一个很好的例子是上面的英特尔音频驱动程序，在停止音频后它不再处于活动状态。

我的罪魁祸首是过程 - Connectifyd。

尽管如此，要相应地覆盖键入此命令：

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

积分：Simplifyze（Reddit）；有没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？

Answer 2

看起来这个问题可能是由于 USB Root Hub 被允许唤醒您的电脑造成的。您会尝试取消选中该框以查看它是否有效吗？步骤如下：

1. 在开始栏中搜索“设备管理器”。
2. 打开设备管理器后，在底部附近展开“通用串行总线控制器”
3. 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。
4. 右键单击 USB Root Hub > 属性 > 电源管理。
5. 取消选中“允许此设备唤醒计算机”
6. 好的 - 测试解决方案。如果该解决方案不起作用，请在重新检查复选框之前尝试重新启动。

让我们知道这是否有效！
