function Set-DbaPowerPlan { <# .SYNOPSIS Sets the SQL Server OS's Power Plan. .DESCRIPTION Sets the SQL Server OS's Power Plan. Defaults to High Performance which is best practice. If your organization uses a custom power plan that is considered best practice, specify -CustomPowerPlan. References: https://support.microsoft.com/en-us/kb/2207548 http://www.sqlskills.com/blogs/glenn/windows-power-plan-effects-on-newer-intel-processors/ .PARAMETER ComputerName The server(s) to set the Power Plan on. .PARAMETER Credential Specifies a PSCredential object to use in authenticating to the server(s), instead of the current user account. .PARAMETER PowerPlan Specifies the Power Plan that you wish to use. Valid options for this match the Windows default Power Plans of "Power Saver", "Balanced", and "High Performance". .PARAMETER CustomPowerPlan Specifies the name of a custom Power Plan to use. .PARAMETER InputObject Enables piping from Get-DbaPowerPlan .PARAMETER 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. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .NOTES Tags: PowerPlan, OS, Configure Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT Requires: WMI access to servers .LINK https://dbatools.io/Set-DbaPowerPlan .EXAMPLE PS C:\> Set-DbaPowerPlan -ComputerName sql2017 Sets the Power Plan to High Performance.
