SetSystemPowerState( NULL , POWER_STATE_RESET , POWER_FORCE ) ;
这个函数可以让机器reset
而在backlight 熄灭后的唤起则可用下面的函数
关于Suspend后也可以用此方法叫起~
void CAutoBackupApp::API_SetPowerStatus(BOOL fBacklightOn)
{
// the name of the backlight device
TCHAR tszBacklightName[] = TEXT("BKL1:");

static HANDLE s_hBacklightReq = NULL;

if (fBacklightOn)
{
if (NULL == s_hBacklightReq)
{
   // Set the requirement that the backlight device must remain
   // in device state D0 (full power)
   s_hBacklightReq = SetPowerRequirement(tszBacklightName, D0,
    POWER_NAME, NULL, 0);
   if (!s_hBacklightReq)
   {
    RETAILMSG(1, (L"SetPowerRequirement failed: %X/n",
     GetLastError()));
   }
}
}
else
{
if (s_hBacklightReq)
{
//释放Requirement
   if (ERROR_SUCCESS != ReleasePowerRequirement(s_hBacklightReq))
   {
    RETAILMSG(1, (L"ReleasePowerRequirement failed: %X/n",
     GetLastError()));
   }
   s_hBacklightReq = NULL;
}
}
}
