在 Windows 7上,我看到使用参数ES_CONTINUOUS调用SetThreadExecutionState. ES_SYSTEM_REQUIRED | ES_AWAYMODE_REQUIRED阻止用户手动将系统置于睡眠状态.

打开“开始”菜单并选择“睡眠”后,显示屏将关闭,但我的应用程序将继续处理.风扇继续全速运行并且在唤醒计算机时,我可以看到睡眠发生时正在进行的操作已经取得了进展.

当SetThreadExecutionState生效时,如何让用户手动将计算机置于睡眠状态？

解决方法

包含ES_AWAYMODE_REQUIRED选项会导致此问题.引用MSDN文章：

The ES_AWAYMODE_REQUIRED value should be used only when absolutely necessary by media applications that require the system to perform background tasks such as recording television content or streaming media to other devices while the system appears to be sleeping. Applications that do not require critical background processing or that run on portable computers should not enable away mode because it prevents the system from conserving power by entering true sleep.
