Hi, everyone.
I hope to use powercfg command code to uncheck the power setting of "Allow the computer to turn off this device to save power" of my network chip named as Intel(R) Ethernet Connection (12) I219-V.
Q. Please you tell me that the command code of powercfg can uncheck the power setting of "Allow the computer to turn off this device to save power" as aforementioned.
Thanks a lot.
Is there a reason why you cannot uncheck the box,without going through ---powercfg /requestoverride---?
I've never used that command.
TL;DR - IMO it cannot be done in the way that OP wishes... but happy to be corrected.
More info:
IMO there is no switch that can be used by powercfg to do what OP wants.
Powercfg is a blanket policy (across devices) and not able to successfully use the /REQUESTSOVERRIDE switch on just a single ethernet device's driver to do what OP wants. That's not its purpose.
(Just Google powercfg /requestoverride to see how many responses there are saying it doesn't work for amending powersaving on individual devices. However, I'm happy to be corrected on this.)
If OP uses Sysinternals/TechNet's Process Monitor (ProcMon) then OP can see the processes involved in making the change from one powersaving state to another on a network device... and it's a PnP setting in the registry for the device's driver. (Note: I'm aware that I do not have the exact same Intel ethernet device but the principle is the same.)
Firstly, I used Windows' built-in Device Manager to expose the Power Management tab for the ethernet device's driver properties in my Dell Latitude E7450 laptop:
... then I removed the tick in the Allow the computer to turn off this device to save power checkbox whilst ProcMon watched what was happening under the bonnet.
Secondly, let me point out that I kept all event categories (i.e. I did not turn off any of the 'Show' icons in the toolbar a). However, ProcMon captures so many hundreds of events per second that I filtered over and over to reduce the captured events to only those relevent to unticking the Allow the computer to turn off this device to save power checkbox, i.e. reducing over 132k of captured events to the 19 that show what happened using the Device Manager UI.
Here's a ProcMon screenshot of the very heavily filtered result:
Here's the key:
a - Shows that all event categories are shown and not filtered.
b - The first 9 events show that Windows Connection Manager (WcmSvc) queries whether there is any Power Saving local group policy in place.
c - Shows that a report is logged.
d - Shows enumeration of the ethernet device's capabilities using the information stored in the registry by the device driver (under its unique PCI vendor/ID entry in enumerated devices).
e - Shows the single DWORD change to the device driver's registry entry following removal of the tick in the Allow the computer to turn off this device to save power checkbox.
f - Shows a follow-up enumeration of the ethernet device's capabilities using the information stored in the registry by the device driver.
g - Shows the exit from Device Manager's UI following the change.
Conclusion: Feel free to differ but I believe all the OP needs is a simple REG file reflecting the single change to the device's powersaving status.
(Off-topic: Thank you to OP. This was something I meant to look into so long ago and it just got buried amongst all the other 'to do' entries in an ever-expanding list.)
Hope this helps...

Hi, joeandmarg0.
I just didn't want to see many times of annoying warning of NDIS as the picture as attached.

Your information were very useful. They were which I just wanted.
It might be the only one way to unchecked "Allow the computer to turn off this device to save power" of my network chip named as Intel(R) Ethernet Connection (12) I219-V by using registry key.
Thanks a lot, RickC.
I believe the registry change won't take effect until the device is disabled/enabled (or until the system is restarted). See: PowerShell One-Liner to Configure the NIC Power Management Settings ~ Mick's IT Blogs
