那些遇到过的问题

如何通过注册表或命令行更改电源选项？

Xeн*_*вϵς 4 windows-registry command-line power-management windows-10

我想powercfg.cpl直接通过注册表更改“电源选项”。

具体来说我想改变这一点：

对于这些设置：

我使用的是交流电源台式电脑，因此不需要节电，而且会影响性​​能；我在 BIOS 中禁用了快速启动。

我已在以下位置打开此注册表项regedit.exe：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
Run Code Online (Sandbox Code Playgroud)

我在钥匙里唯一能看出的东西是：

HiberFileSizePercent REG_DWORD 0
HibernateEnabled REG_DWORD 0
HibernateEnabledDefault REG_DWORD 1

我尝试使用powercfg.exe，这就是我得到的：

这些我实在是一点都看不懂……

我不想手动执行此操作，如何使用脚本自动将电源选项更改为上面发布的设置？

这些powercfg设置并不太难理解。这是我的显示器睡眠设置；

  Subgroup GUID: 7516b95f-f776-4464-8c53-06167f40cc99  (Display)
    GUID Alias: SUB_VIDEO

前几行包含设置的唯一标识符。

  • 显示组的 ID（以 751 开头）
  • “关闭显示”设置的 ID（以 3c0 开头）
  • 此设置的最大和最小允许值显示在值 0 和 ffffffff 之间。
  • 设置的分辨率，在本例中增量为 1。
  • 该值测量的单位，本例为秒。
  • 当前的交流和直流设置均设置为 0x384，十进制表示为 900 秒，即 15 分钟。

/SETACVALUEINDEX我们可以使用( 或/SETDCVALUEINDEX)设置交流（或直流）值

  • 首先，我们指定电源设置方案（通过 GUID），在您的情况下使用列出的/l，活动设置是高性能设置，其 GUID 为：8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c
  • 然后我们指定子组 GUID，在我的例子中，显示设置 GUID 是：7516b95f-f776-4464-8c53-06167f40cc99
  • 接下来是设置 GUID：3c0bc021-c8a8-4e07-a973-6b14cbcb2b7e
  • 然后是我们想要的新值，可以是十进制（或前面带有 0x 的十六进制）

这是您用来更改 AC 显示睡眠设置的命令；

powercfg /SETACVALUEINDEX fb5220ff-7e1a-47aa-9a42-50ffbf45c673 7516b95f-f776-4464-8c53-06167f40cc99 3c0bc021-c8a8-4e07-a973-6b14cbcb2b7e 600

这是使用我机器上的 GUID，将睡眠超时设置为 10 分钟（600 秒）

您还可以使用命令中列出的 GUID 别名/q；

  • SUB_VIDEO是别名7516b95f-f776-4464-8c53-06167f40cc99
  • VIDEOIDLE是别名3c0bc021-c8a8-4e07-a973-6b14cbcb2b7e

我假设这些别名在机器上是相同的。电源方案没有别名。所以命令是；

powercfg /SETACVALUEINDEX fb5220ff-7e1a-47aa-9a42-50ffbf45c673 SUB_VIDEO VIDEOIDLE 600
