[KB]Windows 11自动黑屏，疑似自动进入休眠状态

问题现象：

Windows 11在电源现象中设置了，永不睡眠(Sleep)；
永不关闭Disk等电源设置项目后，依旧会自动进入疑似休眠的状态。

可以尝试以下方法：

# 查看当前设定
PS C:\Users\Administrator> powercfg -a
The following sleep states are available on this system:
    Standby (S3)
    Hibernate
    Hybrid Sleep
    Fast Startup

The following sleep states are not available on this system:
    Standby (S1)
        The system firmware does not support this standby state.

    Standby (S2)
        The system firmware does not support this standby state.

    Standby (S0 Low Power Idle)
        The system firmware does not support this standby state.

PS C:\Users\Administrator>
# 关闭休眠
PS C:\Users\Administrator>
PS C:\Users\Administrator> powercfg /hibernate off
PS C:\Users\Administrator>
# 再次检查
PS C:\Users\Administrator>
PS C:\Users\Administrator> powercfg -a
The following sleep states are available on this system:
    Standby (S3)

The following sleep states are not available on this system:
    Standby (S1)
        The system firmware does not support this standby state.

    Standby (S2)
        The system firmware does not support this standby state.

    Hibernate
        Hibernation has not been enabled.

    Standby (S0 Low Power Idle)
        The system firmware does not support this standby state.

    Hybrid Sleep
        Hibernation is not available.

    Fast Startup
        Hibernation is not available.

PS C:\Users\Administrator>

如果还不行，可以再试试：
设备管理器 --> Inter(R) Management Engine Interface #1 --> 属性 --> 取消其"All the computer to turn off this device to save power"的设定

如果还是有问题，有个终极大招，不过要修改计算机的注册表（因为注册表的操作一般建议高级用户、管理员和IT专业人员操作，非专业人员慎重考虑！）

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\8ec4b3a5-6868-48c2-be75-4f3044be88a7

中的Attributes值修改为：2。
其默认值是1。

修改后就会按照电源计划里实际设定的时间关闭屏幕了。（修改注册表后，重启计算机）
