如何关闭'允许混合睡眠'在高级电源设置中?c#

如果你的目标是Windows 7/2008服务器，那么你可以使用WMI和Win32_PowerSetting类。下面是这样做的代码。确保在System.Management中添加一个程序集引用和using指令。

    private bool SetAllowHybridSleep(bool enabled)
    {
        //Machine to work on, "." for local
        string RemotePC = ".";
        //Set the namespace to the power namespace, used throughout the function
        ManagementScope ms = new ManagementScope(@"''" + RemotePC + @"'root'cimv2'power");
        //Will hold each of our queries
        ObjectQuery oq = null;
        //Will hold the values of our power plan and the specific setting that we want to change
        Guid PowerPlanInstanceId = Guid.Empty;
        string PowerSettingInstanceId = null;
        //Look for the specific setting that we want
        oq = new ObjectQuery(string.Format("SELECT * FROM Win32_PowerSetting WHERE ElementName = 'Allow hybrid sleep'"));
        using (ManagementObjectSearcher mos = new ManagementObjectSearcher(ms, oq))
        {
            ManagementObjectCollection results = mos.Get();
            foreach (ManagementObject obj in results)
            {
                foreach (PropertyData p in obj.Properties)
                {
                    if (p.Name == "InstanceID")
                    {
                        //This will give us a string with a GUID specific to our setting
                        PowerSettingInstanceId = p.Value.ToString();
                        break;
                    }
                }
            }
        }
        //Sanity check
        if (string.IsNullOrEmpty(PowerSettingInstanceId))
        {
            Console.WriteLine("System does not support hybrid sleep");
            return false;
        }
        //Look for the active power scheme
        oq = new ObjectQuery("SELECT * FROM Win32_PowerPlan WHERE IsActive=True");
        using (ManagementObjectSearcher mos = new ManagementObjectSearcher(ms, oq))
        {
            ManagementObjectCollection results = mos.Get();
            foreach (ManagementObject obj in results)
            {
                foreach (PropertyData p in obj.Properties)
                {
                    if (p.Name == "InstanceID")
                    {
                        //The instance contains a string with a GUID inside of it, use the code below to get the GUID by itself
                        if (!Guid.TryParse(System.Text.RegularExpressions.Regex.Match(p.Value.ToString(), @"'{[0-9a-f]{8}'-[0-9a-f]{4}'-[0-9a-f]{4}'-[0-9a-f]{4}'-[0-9a-f]{12}'}").Value, out PowerPlanInstanceId))
                        {
                            Console.WriteLine("Could not find active power plan");
                            return false;
                        }
                        break;
                    }
                }
            }
        }
        //Now we need to update the actual power setting in the active plan
        //Get all power schemes for the target setting
        oq = new ObjectQuery(string.Format("ASSOCIATORS OF {{Win32_PowerSetting.InstanceID='"{0}'"}} WHERE ResultClass = Win32_PowerSettingDataIndex", PowerSettingInstanceId.Replace(@"'", @"''")));
        using (ManagementObjectSearcher mos = new ManagementObjectSearcher(ms, oq))
        {
            ManagementObjectCollection results = mos.Get();
            foreach (ManagementObject obj in results)
            {
                foreach (PropertyData p in obj.Properties)
                {
                    //See if the current scheme is the current setting. This will happen twice, once for AC and once for DC
                    if (p.Name == "InstanceID" && p.Value.ToString().Contains(PowerPlanInstanceId.ToString()))
                    {
                        //Change the value of the current setting
                        obj.SetPropertyValue("SettingIndexValue", (enabled ? "1" : "0"));
                        obj.Put();
                        break;
                    }
                }
            }
        }
        return true;
    }

使用procmon，我设法找出了以下注册表项在我的机器上负责。

HKEY_LOCAL_MACHINE ' SYSTEM ' CurrentControlSet '控制' ' PowerSettings ' 238年c9fa8 - 0 -广告- 41 - ed - 83 - f4 - 97 be242c8f20 ' 94 ac6d29 - 73 - ce - 41 - a6 - 809 f - 6363 ba21b47e

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。

您也可以调用powercfg实用程序来执行此操作。每一种功率设置都可以通过三个方面来识别:

1. 电源配置文件GUID
2. 配置文件子组GUID
3. 设置的GUID

您可以使用powercfg -QUERY生成一个完整的值列表。

一旦你得到了你想要编辑的配置文件的GUID，子组的GUID(在这种情况下是睡眠子组)和设置的GUID(允许混合睡眠)，你可以使用powercfg -SETACVALUEINDEX插入或powercfg -SETDCVALUEINDEX电池来设置值。

在我的情况下(Win7 Ultimate x64)，你可以关闭它使用:
powercfg -SETACVALUEINDEX 381b4222-f694-41f0-9685-ff5bb260df2e 238c9fa8-0aad-41ed-83f4-97be242c8f20 94ac6d29-73ce-41a6-809f-6363ba21b47e 1

这转换为AcSettingIndex值在:
HKEY_LOCAL_MACHINE'SYSTEM'CurrentControlSet'Control'Power'PowerSettings'238C9FA8-0AAD-41ED-83F4-97BE242C8F20'94AC6D29-73CE-41A6-809F-6363BA21B47E'DefaultPowerSchemeValues'381b4222-f694-41f0-9685-ff5bb260df2e
