最近由于项目的需要一直在搞WIN7的电源管理方案,本来想在网上查点类似的代码,可是搜了许久,一点有用的知识也没有,索性自己来研究了,MSDN上面说的到挺详细,不过没有示例,一些参数总是搞不明白,而且WIN7下的电源管理方案的API函数和XP下有了很大的改变,写这篇文章的目的:一是帮助向我这样苦苦搜索类似的资料的同行人,二是做一个笔记避免将来自己忘掉,做一个备份. 要提起WIN7的电源管理方案,首先要说的就是GUID,在WIN7下每一个设备都给分配了一个GUID,电源管理方案,同样如此,这里主要用到了三种GUID: 1.SchemeGuid 这个是用来标示电源管理方案的,就是在WIN7下我们看到什么平衡模式,节能模式,高性能模式. const GUID FAR GUID_POWER_SAVER ={ 0xa1841308, 0x3541, 0x4fab, { 0xbc, 0x81, 0xf7, 0x15, 0x56, 0xf2, 0x0b, 0x4a } }; //节能 //a1841308-3541-4fab-bc81-f71556f20b4a const GUID FAR GUID_BALANCED ={ 0x381b4222, 0xf694, 0x41f0, { 0x96, 0x85, 0xff, 0x5b, 0xb2, 0x60, 0xdf, 0x2e } }; //平横 //381b4222-f694-41f0-9685-ff5bb260df2e const GUID FAR GUID_HIGH_PERFORMANCE ={ 0x8c5e7fda, 0xe8bf, 0x4a96, { 0x9a, 0x85, 0xa6, 0xe2, 0x3a, 0x8c, 0x63, 0x5c } }; //高性能这是WIN7下的三种电源管理方案的三种模式的GUID,这些东西是不变的. 2.Subgroup GUID 也就是API函数中SubGroupOfPowerSettingsGuid 这个参数是每个电源管理方案下每个小组的的GUID,这个参数非常重要,控制每组的参数全指望它了. ValueMeaning

NO_SUBGROUP_GUID
fea3413e-7e05-4911-9a71-700331f1c294

Settings in this subgroup will be part of the default power scheme.

GUID_DISK_SUBGROUP
0012ee47-9041-4b5d-9b77-535fba8b1442

Settings in this subgroup control power management configuration of the system's hard disk drives.

GUID_SYSTEM_BUTTON_SUBGROUP
4f971e89-eebd-4455-a8de-9e59040e7347

Settings in this subgroup control configuration of the system power buttons.

GUID_PROCESSOR_SETTINGS_SUBGROUP
54533251-82be-4824-96c1-47b60b740d00

Settings in this subgroup control configuration of processor power management features.

GUID_VIDEO_SUBGROUP
7516b95f-f776-4464-8c53-06167f40cc99

Settings in this subgroup control configuration of the video power management features.

GUID_BATTERY_SUBGROUP
e73a048d-bf27-4f12-9731-8b2076e8891f

Settings in this subgroup control battery alarm trip points and actions.

GUID_SLEEP_SUBGROUP
238C9FA8-0AAD-41ED-83F4-97BE242C8F20

Settings in this subgroup control system sleep settings.

GUID_PCIEXPRESS_SETTINGS_SUBGROUP
501a4d13-42af-4429-9fd1-a8218c268e20

Settings in this subgroup control PCI Express settings. 上面这些是所有的Subgroup GUID. 3.还有最后一个参数就是Power Setting GUID,刚开始搞时也就是这个参数困忧了我很长时间,一直不知道是做什么用的,后来才知道,他是Subgroup GUID 的子项,也就是组选项下面的小选项.这个里面涉及的参数比较多,API没有给出详细的GUID 不过我都导出来了,供大家使用方便和自己查询.

    Current AC Power Setting Index: 0x00000001
    Current DC Power Setting Index: 0x00000000 上面把参数介绍个差不多了,下面开始创建电源管理方案,WIN7下创建电源管理方案和XP下不一样,需要以下几步: 1.首先复制一个现有的电源管理方案.要用的API函数是:

DWORD WINAPI PowerDuplicateScheme(
  __in_opt  HKEY RootPowerKey,
  __in      const GUID *SourceSchemeGuid,
  __in      GUID **DestinationSchemeGuid
);

下面是示例代码: WCHAR displayBuffer[_MAX_PATH]=L"超级节能";
DWORD displayBufferSize =_MAX_PATH; //sizeof(displayBuffer);
GUID *GUID_HIGH_POWERSAVE=NULL; //创建新的电源管理方案声成的的GUID
if(ERROR_SUCCESS== PowerDuplicateScheme(NULL,&GUID_POWER_SAVER,&GUID_HIGH_POWERSAVE))//GUID_POWER_SAVER是复制节能模式的方案
{
MessageBox("DuplicateScheme ok");
} 2.复制电源管理方案后,下面是把它定义成我们自己的,首先对它进行改名和自定义描述,用的API是:

DWORD WINAPI PowerWriteFriendlyName(
  __in_opt  HKEY RootPowerKey,
  __in      const GUID *SchemeGuid,
  __in_opt  const GUID *SubGroupOfPowerSettingsGuid,
  __in_opt  const GUID *PowerSettingGuid,
  __in      UCHAR *Buffer,
  __in      DWORD BufferSize
);

DWORD WINAPI PowerWriteDescription(
  __in_opt  HKEY RootPowerKey,
  __in      const GUID *SchemeGuid,
  __in_opt  const GUID *SubGroupOfPowerSettingsGuid,
  __in_opt  const GUID *PowerSettingGuid,
  __in      UCHAR *Buffer,
  __in      DWORD BufferSize
);

示例代码为: if(ERROR_SUCCESS==
   PowerWriteDescription(
   NULL,
   GUID_HIGH_POWERSAVE,
   NULL,//大家可以根据这里的参数来修改给那个参数描述要是下面这两项都为空,默认是电源管理方案的描述.
   NULL,
   (UCHAR*)displayBuffer,//这里大家一定要注意,WIN7只认宽字符,要是定义时一定要定义成WCHAR 否则会乱码.
   displayBufferSize
   ))
{
MessageBox("PowerWriteDescription");
}
else
{
CString outString;
DWORD mm=GetLastError();
outString.Format("%d",mm);
}
if(ERROR_SUCCESS==
   PowerWriteFriendlyName(
   NULL,
   GUID_HIGH_POWERSAVE,
   NULL,//
   NULL,
(UCHAR*)displayBuffer,
displayBufferSize
   ))
{
MessageBox("PowerWriteFriendlyName");
}
else
{
CString outString;
DWORD mm=GetLastError();
outString.Format("%d",mm);
} 4.这里就是修改我们自己需要的参数设置了: 这里用的函数比较多,主要是分成AC,DC模式的设置,大家根据参数的不同就可以设置自己需要的不同参数了,这里简单介绍一个函数,用的API函数为

DWORD WINAPI PowerWriteDCValueIndex(
  __in_opt  HKEY RootPowerKey,
  __in      const GUID *SchemeGuid,
  __in_opt  const GUID *SubGroupOfPowerSettingsGuid,
  __in_opt  const GUID *PowerSettingGuid,
  __in      DWORD DcValueIndex
);

示例代码是在新建电源管理方案下把处理器降频到%50 GUID FAR MySubGroupOfPowerSettingsGuid={0xbc5038f7, 0x23e0, 0x4960, {0x96, 0xda, 0x33, 0xab, 0xaf, 0x59, 0x35, 0xec} }; if(ERROR_SUCCESS==
   PowerWriteDCValueIndex(
   NULL,
   GUID_HIGH_POWERSAVE,
   &GUID_PROCESSOR_SETTINGS_SUBGROUP,
   &MySubGroupOfPowerSettingsGuid,// &NO_SUBGROUP_GUID,
0x3c
   ))
{
MessageBox("PowerWriteValueMax");
}
else
{
CString outString;
DWORD mm=GetLastError();
outString.Format("%d",mm);
} 好了,这样一个自己需要的电源管理方案用代码就实现出来了,这只是简单介绍了一下思路和方法,有不少的笔记本节能软件就是基于这个原理实现的. 最后在说一句,大家要是转载,请注明出处,毕竟我敲了半个多小时的键盘,没有功劳也有苦劳.
