允许唤醒定时器Windows 7 / Vista

我需要允许WakeTimers(计算机从睡眠/休眠状态唤醒)将插入的所有电源计划设置为已启用。

wake timers -> power options

我尝试过Win32_PowerSetting,但它只适用于英文版的Windows。

我需要使用.NET 2.0

感谢您的回复!

我怀疑你可以使用对powrprof.dll以及WMI的API调用来做到这一点,但我还没有时间去解决这个问题。

此设置似乎只是一个布尔注册表项,根据您当前的电源计划定位:

  

HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Power \ User \ PowerSchemes \(当前电源方案GUID)\(睡眠类别GUID)\(启用AC或DC唤醒定时器GUID)= 0或1

不是直接操作注册表,而是使用powercfg.exe启用这些设置。

对于交流电源:

powercfg.exe -SETACVALUEINDEX SCHEME_CURRENT SUB_SLEEP bd3b718a-0680-4d9d-8ab2-e1d2b4ac806d 1

对于电池:

powercfg.exe -SETDCVALUEINDEX SCHEME_CURRENT SUB_SLEEP bd3b718a-0680-4d9d-8ab2-e1d2b4ac806d 1

编辑:

使用高性能电源方案(纯粹作为概念验证),在使用交流电源运行时,可在系统上启用唤醒定时器:

[DllImport("powrprof.dll", EntryPoint = "PowerWriteACValueIndex", CharSet = CharSet.Auto, SetLastError = true)]
public static extern uint PowerWriteACValueIndex(IntPtr RootPowerKey, ref Guid SchemeGuid, ref Guid SubGroupOfPowerSettingsGuid, ref Guid PowerSettingGuid, uint AcValueIndex);

public static void EnableWakeTimers()
{
    Guid Root = new Guid("8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c"); // High Performance GUID
    Guid Sleep = new Guid("238c9fa8-0aad-41ed-83f4-97be242c8f20"); // Sleep Subcategory GUID
    Guid WakeTimers = new Guid("bd3b718a-0680-4d9d-8ab2-e1d2b4ac806d"); // Wake Timers GUID

    PowerWriteACValueIndex(IntPtr.Zero, ref Root, ref Sleep, ref WakeTimers, 1);
}

您似乎可以使用WMI更改设置。

Microsoft有一个WMI代码创建器可以帮助您:

您需要在“root \ CIMV2 \ power”下搜索电源管理内容。

我写了这个powershell脚本来启用或禁用所有当前电源方案的唤醒定时器。在第二行" POWERCFG -setacvalueindex $ xAll $ xSubGuid $ zz 1" - 1表示启用。只需将其更改为0即可禁用。

CLS
#Capture Current Active Power Scheme
$orgScheme = POWERCFG -GETACTIVESCHEME  
$yOrg = $orgScheme -split "\s+"
$xOrg = $yOrg[3]
Write-host Original Scheme = $xOrg
Echo __________________________________
Echo " "

$allScheme = POWERCFG /L
#Echo $allScheme

foreach ($line in $allScheme)
  {
  if ($line.Length -gt 40)
        {
        if ($line.substring(0,5) -eq "Power")
            {
            $yAll = $line -split "\s+"
            $xAll = $yAll[3]
            write-host $xAll
            Powercfg -S $xAll

            $pScheme = POWERCFG /Q
            foreach ($line in $pScheme)
                {
                $yy = $line -split "\s+"
                $xx = $yy[5]+$yy[6]+$yy[7]+$yy[8]
                $zz = $yy[4]
                $xSubGroup = $yy[1]

                If($xSubGroup -eq "SubGroup")
                    {
                    $xSubGuid = $yy[3]
                    }

                If($xx -eq "(allowwaketimers)")
                     {
                      write-host Power Scheme Guid = $xAll
                      write-host Subgroup Guid = $xSubGuid
                      write-host WakeUp Guid = $zz
                      Write-host POWERCFG -setacvalueindex $x $xSubGuid $zz 1
                      Echo " "
                      break
                     }
                }
            POWERCFG -setacvalueindex $xAll $xSubGuid $zz 1
            }
        }
  }
Powercfg -S $xOrg

享受。
