Solved Disable Power Management for all devices via script

shoober420 · Nov 2, 2024

Im trying to disable all Power Management options for all devices found under Device Manager. This includes all USB devices and NICs. I came across the "Disable-NetAdapterPowerManagement" command and ran:

Code:

Disable-NetAdapterPowerManagement -Name *

The "Allow the computer to turn off this device to save power" and "Allow this device to wake the computer" were still checkmarked and enabled for my NIC card, even after restart.

Is there another PowerShell command or commands I can run to disable all Power Management options for all my devices?

I have a post for disabling the "wake the computer" option over here: Disable waking up from hibernation for good

If you change the class name in the query to MSPower_DeviceEnable, it should turn off the "turn off this device" option, but I don't have a PC I'm willing to try it on. :)

When i run that command string from the linked thread post, i get this error:

Code:

Set-CimInstance : Invalid object
At line:1 char:1
+ Set-CimInstance -Query 'SELECT InstanceName FROM MSPower_DeviceWakeEn ...

Works fine here, along with changing the class name for the power management setting. Perhaps one of your other performance tweaks rendered this not an option.

I've been looking for something like this, too. Unticking all those Power Management tab boxes in Device Manager is pretty tedious.

Im on a fresh WinRE restart (keep my files), so the machine hasnt had any tweak scripts applied to it. I will try and look into why its not working further.

@cheaterslick
I made a script that will disable all the power management options for all devices based on pseymours command string. Could you test it out? Make sure your "Set-ExecutionPolicy" allows scripts from the internet to be launched.

@shoober420 PowerShell has a pause command also; you can avoid calling out to cmd if you want.

I was looking for it a couple of days ago, and couldnt find anything. The closest thing I found was a "sleep" command, which I dont want.

Code:

Start-Sleep -Seconds 5

Another option I saw when googling was:

Code:

Read-Host -Prompt "Press any key to continue..."

Although it may work, it doesnt actually say "pause" anywhere which bothers me. It also uses more characters for the same effect as whats in the script now.

Heres another one i found googling.

Code:

Wait-Event -sourceIdentifier "ProcessStarted" -timeout 90

This also uses a lot of characters for the same effect as whats in the script. They both also look very ugly.

This is why i opted for whats currently in the script, which is:

Code:

cmd /c 'pause'

I also think this looks a lot nicer than the "Read-Host" method and "Wait-Event" method. It also is more readable, meaning if someone looks at it they can give a guess what it does over "Read-Host -Prompt" and "Wait-Event -sourceIdentifier". IMO, the other methods simply look ugly.

I thought I found a work around but was out of luck. I came across the powercfg method in the thread you posted in. Although the powercfg method would work, I have to specify a specific device to disable power management options for. Im trying to simply disable for all devices across multiple different computers. Making a script with specific hardware names is not what im looking for. Using "*" unfortunately doesnt work.

Code:

powercfg -devicedisablewake "*"

By golly, I think I did it, at least for the network adapter thus far. Registry method, the true method. We are looking for the PnPCapabilities registry key that effects all power management options.

Power management setting on a network adapter - Windows Client

This article talks about the power management setting on a network adapter. Provides resolutions to disable the network adapter power management on a single computer.

learn.microsoft.com

Fortunately, its under the same registry key string as the other NIC options under NIC properties.

Code:

for /f %%n in ('Reg query "HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}" /v "*SpeedDuplex" /s ^| findstr  "HKEY"') do (

reg add "%%n" /v "PnPCapabilities" /t REG_DWORD /d "0x00000118" /f

or you can use the old way i used to do.

Code:

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

for 000X, would be 0, 1, 2, 3, 4 etc depending on how many devices are present

this bypasses the need for using powershell to modify registry. we talk directly to registry and avoid the need for powershell to do this for us

ill post back later with how to do this for usb devices

Thanks but I did the dirty time-consuming deed, already. I can see why MS has them enabled by default for enterprise use, but for home users to have to go through all that crap...

Not good.

The powercfg -devicequery wake_armed command was a big help in tracking down the ones that I missed.

However, once you and @pseymour work it out, I will be able to save your script for future use because I know I will run into this again.

I want to thank both of you for your efforts.

looks like its complete. im just hoping the "class guid" is consistant for mice and keyboards on windows. it would appear to be, as ive come across many threads about NICs and the "class guid" being the same as mine.

Code:

rem # Disable Power Management option on all devices

rem # NIC
for /f %%n in ('Reg query "HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}" /v "*SpeedDuplex" /s ^| findstr  "HKEY"') do (

reg add "%%n" /v "PnPCapabilities" /t REG_DWORD /d "0x00000118" /f
)

rem # Keyboard
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-bfc1-08002be10318}\0000" /v "PnPCapabilities" /t REG_DWORD /d "0x00000118" /f

rem # Mouse
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e96f-e325-11ce-bfc1-08002be10318}\0000" /v "PnPCapabilities" /t REG_DWORD /d "0x00000118" /f

Neato, but you said all devices, not NICs and input devices. The customer changed the specs mid-stream!

shoober420 · Nov 2, 2024

i spoke too soon, it doesnt work. i of course want them disabled for all devices, its just input and NICs are most common. im going to still try and figure out how to do this. windows shouldnt make it this hard. no one wants to go through every devices properties and manually untick everything. thats windows for you

Almost no one wants these settings disabled for all devices. For those that do, that’s why MSFT added the WMI functions, accessible via PowerShell and other methods.

me saying "no one" doesnt mean im speaking for everyone, it means im speaking for the people who tweak their system, like gamers or powerusers in a corporate environment. what other methods?

pseymour · Nov 2, 2024

Anything that can run WMI functions. VBScript, .NET code, WMIC? Not sure about WMIC; never checked and it's deprecated now anyway. But these days, if you're doing something new, PowerShell is the way to go, and that's what my suggestion was above.

shoober420 · Nov 2, 2024

@pseymour vbscript is deprecated too. do you know how to do the ".net code" method?

pseymour · Nov 2, 2024

Not sure why you seem intent on avoiding PowerShell, but here ya go...

Call a WMI Class Method by Using System.Management - Configuration Manager

To call a client Windows Management Instrumentation (WMI) class method, call the InvokeMethod of the WMI class's ManagementClass.

because this isnt the first time ive ran into trouble with powershell. i even googled how to disable the power management options for the usb controllers and another powershell command string failed.

https://www.reddit.com/r/PowerShell/comments/lr5iyk/uncheck_allow_the_computer_to_turn_off_this

other powershell commands seem to work for me. my NICProperties.ps1 powershell scripts works. i ran "winget install microsoft.powershell" to make sure i have the latest powershell and i do. maybe its a bug with the windows insider build im on (27729).
