多种方式查看电脑是否支持Modern Standby

控制台查看

CMD输入powercfg /a

显示如下有S0，则支持Modern Standby

注册表查看

Win+R 输入regedit进入注册表，

查看HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\ModernSleep路径下有否有参数EnabledActions=7

C++代码查看

C#代码查看

关闭/开启机器的Modern Standby(前提是电脑支持,不然开了也没用)

close:创建*.reg后缀文件，复制下面文本放进去运行

open:创建reg后缀文件，复制下面文本放进去运行
