如何关闭'；允许混合睡眠'；在高级电源设置中？由c#

如何在高级电源设置中关闭“允许混合睡眠”？由c# 手动：电源选项->更改计划设置->更改高级电源设置->

Sleep->“Allow hybrid Sleep”->“Plugh-in:OFF

使用procmon，我设法确定以下注册表项负责我的机器上的睡眠

HKEY\U LOCAL\U MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\94ac6d29-73ce-41a6-809f-63BA21B47E

你可能需要对你的机器做一些研究，看看它是如何为你工作的

您还可以调用powercfg实用程序来执行此操作。每个电源设置由三个部分标识：

电源配置文件的GUID

配置文件子组的GUID

设置的GUID

您可以使用

powercfg-QUERY

生成完整的值列表

获得要编辑的配置文件的GUID、子组的GUID（在本例中为睡眠子组）和设置的GUID（允许混合睡眠）后，您可以使用

powercfg-SETACVALUEINDEX

进行插入式设置，或使用

powercfg-SETDCVALUEINDEX

进行电池充电设置

在我的情况下（Win7 Ultimate x64），您可以使用以下命令将其关闭：

powercfg-SETACVALUEINDEX 381b4222-f694-41f0-9685-ff5bb260df2e 238c9fa8-0aad-41ed-83f4-97be242c8f20 94ac6d29-73ce-41a6-809f-6363ba21b47e 1

这将转换为中的AcSettingIndex值：

如果您的目标是Windows 7/2008服务器，则可以使用WMI和该类。下面是实现这一点的代码。确保使用指令向

请记住，“混合睡眠”在Windows7中只是“睡眠”，你确定吗？我与win7操作系统一起使用，因此看起来“允许混合睡眠”是的，电源选项在那里，但当你实际按下“睡眠”按钮时，它将根据电源选项进行正常或混合睡眠。这最好与组策略一起完成，操作注册表项或使用powercfg就可以了。电源管理api是解决问题的正确方法，但组策略听起来更合适effective@DavidHeffernan-我倾向于对一切进行逆向工程，只是为了实现它；）@大卫·费弗南——当然。我还没有接触过电源管理API，所以我想我应该了解控制面板和powercfg是如何做到这一点的。是否愿意发布一个答案，详细说明如何使用电源管理API实现此功能？很高兴我能提供一些帮助：）
