Click on the link, and let us see the resulting options by supplying another screenshot.

Actually what are you wanting to do?

Hi,

I turned it off, see new screenshot.

Now the poercfg returns 3 errors.

Error #1 = Processor at work (no problem for me)

Error #2 = PCI Express-ASPM ist off (it's true, I configured it)

Error #3 = PCI Express-ASPM (Active-State Power Management) is deactived (by the system) because of
incompatiblewurde Computerhardware.



And now?

When i do use the command "powercfg" same as you, it does returns me exactly the same results (Error #3).

I think the Operating System disable it in a kind of automatic mode and is a normal behavior when launching the "powercfg -energy -output %USERPROFILE%\Desktop\Energy_Report.html" command

I have a power meter that counts tenths of Watt on my PC.
I see no difference at all between off, moderate and maximum.
When is it supposed to kick in when monitor goes on standby ?

Hello James,

Here's a bit more info from Microsoft for this.
