电源计划是计算机的重要组成部分，尤其是在使用电池运行的笔记本电脑时。它可以确保您最终不会消耗大量电力或耗尽电池。当您需要比平时更高的性能时，它们也是必不可少的。PowerCFG命令提供了一种无需打开^(PowerCFG)Windows用户界面即可在计划之间快速切换的方法。这篇文章将指导您在 Windows 10 中使用 powercfg 命令行更改Windows电源计划。

^{(Change Power Plan)}使用PowerCFG^(PowerCFG)命令行更改电源计划类型

您需要做的第一件事是创建电源计划。Windows 提供平衡电源计划^{(Balanced Power Plan)}作为唯一的电源计划。但是您可以转到Control Panel > Power Options>创建电源计划。

完成后，在运行提示符中键入CMD，然后使用Shift + Enter以管理员权限  打开命令提示符。^{(Command Prompt)}接下来^(Next)，按照指南了解如何更改它。

更改电源计划类型的步骤

执行以下命令：

C:\Windows\system32>powercfg -LIST

您将看到以下输出：

Existing Power Schemes (* Active)
-----------------------------------
Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e (Balanced)
Power Scheme GUID: 8212ee68-2253-4280-bf84-6891b94d6012 (Power Saver) *
Power Scheme GUID: a24a6a37-5ab8-4286-bed5-866c730152ee (High Performance)

Next execute the following:

C:\Windows\system32>powercfg -SETACTIVE 381b4222-f694-41f0-9685-ff5bb260df2e

C:\Windows\system32>powercfg -LIST

您将看到以下输出：

Existing Power Schemes (* Active)
-----------------------------------
Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e (Balanced) *
Power Scheme GUID: 8212ee68-2253-4280-bf84-6891b94d6012 (Power Saver)
Power Scheme GUID: a24a6a37-5ab8-4286-bed5-866c730152ee (High Performance)

当您重新运行显示电源计划列表的命令时，Astrix标记是默认或活动电源计划。如果要进一步检查电源计划内的设置，请使用电源计划的查询选项和GUID执行命令。

powercfg /query a24a6a37-5ab8-4286-bed5-866c730152ee

由于名称不友好，您可以使用更改名称选项更改计划名称。

powercfg /changename 24a6a37-5ab8-4286-bed5-866c730152ee "Power Extreme"

也就是说，您还可以将当前的电源计划导出到文件中，然后再导出。在切换到新 PC 或硬重置计算机并需要重新配置计划时，它非常方便。但是，请确保将其放在USB或OneDrive上的计算机之外。

如果经常需要，最好创建一个BAT文件或者桌面快捷方式，快速更改。

How to change the Power Plan type using PowerCFG command line

Power Plan is an impоrtant part of your computer, espеcially іf it’s a laрtop running on battery.  It makes sure you don’t end up consuming a lot of electricity or draіning your battery. They are also essential when yоu need more performance than usual. PowerCFG command offers a way to quickly switch between the plans without opening the Windows user interface. This post will guide you to change the Windows power plan using the powercfg command line in Windows 10.

Change Power Plan type using PowerCFG command line

The first thing you will need to do is create power plans. Windows offers Balanced Power Plan as the only power plan. But you can go to Control Panel > Power Options > Create a power plan.

Once done, type CMD in the run prompt, and then use Shift + Enter to open Command Prompt with admin privileges.  Next, follow the guide to learn how to change it.

Steps to change Power Plan type

Execute the following command:

C:\Windows\system32>powercfg -LIST

You will see the following output:

Existing Power Schemes (* Active)
-----------------------------------
Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e (Balanced)
Power Scheme GUID: 8212ee68-2253-4280-bf84-6891b94d6012 (Power Saver) *
Power Scheme GUID: a24a6a37-5ab8-4286-bed5-866c730152ee (High Performance)

Next execute the following:

C:\Windows\system32>powercfg -SETACTIVE 381b4222-f694-41f0-9685-ff5bb260df2e

C:\Windows\system32>powercfg -LIST

You will see the following output:

Existing Power Schemes (* Active)
-----------------------------------
Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e (Balanced) *
Power Scheme GUID: 8212ee68-2253-4280-bf84-6891b94d6012 (Power Saver)
Power Scheme GUID: a24a6a37-5ab8-4286-bed5-866c730152ee (High Performance)

When you rerun the command that displays a list of power plans, the Astrix mark is the default or active power plan. If you want to further check on settings inside the power plan, execute the command with query option and GUID of the power plan.

powercfg /query a24a6a37-5ab8-4286-bed5-866c730152ee

Since the names are not friendly, you can change the plan name using the change name option.

powercfg /changename 24a6a37-5ab8-4286-bed5-866c730152ee "Power Extreme"

That said, you can also export the current power plan into a file and later export it. It comes in extremely handy when switching to a new PC or when you hard reset the computer and need to configure the plan again. However, make sure to keep it off the computer on a USB or OneDrive.

If you need it often, it is best to create a BAT file or a desktop shortcut and change it quickly.
