Required Parameters

-ComputerName

The server(s) to check Power Plan settings on.

Alias
Required True
Pipeline true (ByValue, ByPropertyName)
Default Value

Optional Parameters

-Credential

Specifies a PSCredential object to use in authenticating to the server(s), instead of the current user account.

Alias
Required False
Pipeline true (ByPropertyName)
Default Value
-PowerPlan

If your organization uses a different power plan that's considered best practice, specify it here.

Alias CustomPowerPlan
Required False
Pipeline true (ByPropertyName)
Default Value
-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

Alias
Required False
Pipeline false
Default Value False
