Managing power settings in Windows is essential for optimizing energy efficiency, especially in environments where conserving power is crucial, such as on laptops or in large-scale enterprise deployments. Windows provides a variety of tools and settings to help users manage power consumption effectively.

Examples:

1. Using Power Options in Control Panel:

   • Navigate to the Control Panel.
   • Select "Hardware and Sound" and then "Power Options."
   • Choose a power plan that suits your needs, such as "Balanced," "Power Saver," or "High Performance."
   • You can also create a custom power plan by clicking on "Create a power plan" and following the prompts to configure settings like display brightness, sleep mode, and more.

2. Configuring Power Settings via CMD:

   • Open Command Prompt as an administrator.
   • Use the powercfg command to manage power settings. For example, to view all available power schemes, use:

     powercfg /list

   • To set a specific power scheme as active, use:

     powercfg /setactive <SCHEME_GUID>

   • Replace <SCHEME_GUID> with the GUID of the power scheme you want to activate.

3. Adjusting Power Settings with PowerShell:

   • Open PowerShell as an administrator.
   • To get a list of all power schemes, use:

     powercfg /list

   • To change the active power scheme, use:

     powercfg /setactive <SCHEME_GUID>

4. Using Task Scheduler to Automate Power Management:

   • Open Task Scheduler.
   • Create a new task to change power settings based on specific triggers, such as time of day or battery level.
   • Use the powercfg command within the task to switch power plans automatically.

These methods allow you to efficiently manage power settings in Windows, ensuring that your system uses energy optimally based on your usage patterns and needs.
