A powershell script to enable all advanced power options?

Question

I found one script on the internet, but it doesn't enable all of them. I am looking to enable the maximum CPU usage option and set it to around 80% to prevent the CPU from overheating on my laptop.

This doesn't enable Maximum processor frequency

Answer 1

Here's a PowerShell script I wrote that lists all available POwer Options in a GridView control. Copy the entire script, paste into an Administrative PowerShell console, and press <Enter> to run:

Function Toggle-PowerSettingsVisibility {
    $Title         = 'Select option(s) to toggle visibility'
    $PowerSettings = 'HKLM:\SYSTEM\CurrentControlSet\Control\Power\PowerSettings'
    @( [PSCustomObject]@{
            Attributes  = 0
            PSChildName = '{ -- No Changes -- }'
            Name        = ' "Safety" row to clear selection'
    } ) +
    @( Get-ChildItem $PowerSettings -Recurse | ? Property -contains 'Attributes' | Get-ItemProperty |
        Select Attributes, PSCHildName,
               @{ N = 'Name' ; E = { $_.FriendlyName.Split(',')[-1] }} ) | Sort PSChildName |
    Out-GridView -Passthru -Title $Title | ForEach {
        $Splat = @{
            Path  = Resolve-Path "$PowerSettings\*\$($_.PSChildName)"
            Name  = 'Attributes'
            Value = $_.Attributes -bXor 0x0000003 
        }
        Set-ItemProperty @Splat
    }
}
Toggle-PowerSettingsVisibility

THe Attributes column displays 2 for visible items and 1 for hidden items:

Type Maximum in the Filter textbox, select your desired option(s) and click OK:

That's it!

Taken from https://superuser.com/a/1689410

As an admin, this PowerShell script will unhide every power option in Power Options after running and restarting.

# Path to PowerSettings in Windows registry
# Set 'Attributes=2' to show in Power Options on each directory and subdirectory
$powerPath = "HKLM\SYSTEM\CurrentControlSet\Control\Power\PowerSettings"
$powerQuery = reg query $powerPath
foreach ($regDir in $powerQuery) {
$subPowerQuery = reg query $regDir
foreach ($subDir in $subPowerQuery) {
    $subActive = $subDir -replace "HKEY_LOCAL_MACHINE" , "HKLM:"
    Get-ItemProperty -Path $subActive
    Set-ItemProperty -Path "$subActive" -Name "Attributes" -Value '2'
}

$active = $regDir -replace "HKEY_LOCAL_MACHINE" , "HKLM:"
Get-ItemProperty -Path $active
Set-ItemProperty -Path "$active" -Name "Attributes" -Value '2'

}

From there you can go

• Power & sleep
• Additional power settings
• Power Options / Change plan settings
• Change advanced power settings

Under the 'Processor power management' tree there are oodles of options. You may be looking for 'Maximum processor state' or another one, I'm not sure.
