Solved Disable Power Management for all devices via script


for what its worth, you can successfully change the power management options of the NIC through registry without powershell with this key.

Code:
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\000X" /v "PnPCapabilities" /t REG_DWORD /d "0x00000118"

you can disable it for other devices using the "ultimate performance" power plan. i havent figured out how to do it for the usb controllers though through registry. im looking into finding a way to do it via powercfg commands. ill post back if i find anything. at least there is a powershell solution that works for mostly everyone if someone comes across this thread

nice, but i did unfortunately find out that powercfg cant do the same for the "Allow the computer to turn off this device to save power" option.

powercfg can't, but PowerShell can. However, I wanted to make sure that you will be able to see what are the devices that have that option currently turned on, i.e. as opposed to merely turning it off for all devices that have that option. In addition, I also wanted to make sure that you will be able to revert these changes if needed (just to be on the safe side). Some reports claim that making these changes can tend to hurt system performance so that's why.

The PowerShell script code below outputs the FriendlyName and the InstanceId [of those specific devices that have the option enabled] to the console, writes the InstanceId values to a file, and disables the option for each device. To be able to see the output in the console, you'll have to run this script code in such a way that the console remains open after it finishes. To be able to see the output in the console more clearly, you can resize the PowerShell window to make it wider.
Powershell:
$PSDefaultParameterValues['out-file:width'] = 4096

$devices = Get-PnpDevice -PresentOnly
$checkedDevices = (Get-CimInstance -ClassName MSPower_DeviceEnable -Namespace root\wmi | Where-Object {$_.Enable}).InstanceName

# Save the InstanceId values to a file
$checkedDevices | Out-File -FilePath "checkedDevices.txt"

# Output the FriendlyName and InstanceId values to the console
$checkedDevices | ForEach-Object {
    $id = $_
    $device = $devices | Where-Object {$_.InstanceId + '_0' -eq $id}
    $device | Select-Object FriendlyName, InstanceId
} | Format-Table -AutoSize | Out-String -Width 4096

# Uncheck "Allow the computer to turn off this device to save power" checkbox for each device
$checkedDevices | ForEach-Object {
    Set-CimInstance $_ -Property @{Enable = $false}
}

$PSDefaultParameterValues.Remove('out-file:width')

The PowerShell script code below reads from the file, and uses that to undo the changes made by the PowerShell script code above.
Powershell:
# Read the InstanceId values from the file
$checkedDevices = Get-Content -Path "checkedDevices.txt"

# Check "Allow the computer to turn off this device to save power" checkbox for each device using the InstanceId values from the file
$checkedDevices | ForEach-Object {
    Set-CimInstance $_ -Property @{Enable = $true}
}
