Your homework...
1. Executing the command:
>@Wmic Path Win32_VideoController Get Name, PNPDeviceID /Value
It returns:
Name=Intel(R) HD Graphics 630
PNPDeviceID=PCI\VEN_8086&DEV_5912&SUBSYS_07A31028&REV_04\3&11583659&0&10
2. With some "crops" done by defining a delimiter in a double for /f loop, I get the "conversion" from, crop to:
:: From: PCI\VEN_8086&DEV_5912&SUBSYS_07A31028&REV_04\3&11583659&0&10
:: Crop: PCI\VEN_8086&DEV_5912&SUBSYS_07A31028&REV_04\3&11583659&0&10
:: Crop: PCI\VEN_8086& DEV_5912& SUBSYS_07A31028
:: To: PCI\VEN_8086&DEV_5912&SUBSYS_07A31028
With this string, I can now check the status of the VGA card with:
DevCon.exe status "PCI\VEN_8086&DEV_5912&SUBSYS_07A31028"
It returns:
PCI\VEN_8086&DEV_5912&SUBSYS_07A31028&REV_04\3&11583659&0&10
Name: Intel(R) HD Graphics 630
Driver is running.
1 matching device(s) found.
I really don't know if this helps to disable and/or enable if the action is dependent on what results in:
Driver is running.
To avoid any anomalies when basing actions on the result of obtaining the current status, I prefer to apply the command to enable the card in your case:
devcon enable "PCI\VEN_8086&DEV_5912&SUBSYS_07A31028"
Which can return if it is disabled
PCI\VEN_8086&DEV_5912&SUBSYS_07A31028&REV_04\3&11583659&0&10: Enable failed
1 matching device(s) found.
To automate actions based on the identification of the enabled/disabled status, you can apply Conditional Execution using the following logic:
>nul devcon enable "PCI\VEN_8086&DEV_5912&SUBSYS_07A31028" && (
:: If the command returns an exit code of 0
:: The device was disabled, no further action is
:: necessary; it has been enabled successfully.
) || (
:: In this condition, the opposite applies,
:: because it returned a non-zero exit code, indicating that
:: the device is enabled, so the next command will disable it.
>nul devcon disable "PCI\VEN_8086&DEV_5912&SUBSYS_07A31028"
)
Note 1. Unfortunately, I don't have dual graphics cards to be able to test and confirm that it "works", but at least I have one card. d;)
My card: Intel(R) HD Graphics 630
Note 2. For obvious reasons and limitations, I cannot provide you with a "ready-to-execute" code. You will have your homework to follow the described steps and adapt the specific strings for your card in the code, as well as download DevCon.exe and set the path to the variable.
Note 3. To obtain DevCon, I recommend using the available installer, which will guide you to the appropriate version for your systems.
Note 4. During the installation, be sure to copy the path and assign this value to the variable:
Set "_DevCon=D:\Full\Path\To\Your\Installed\DevCon.exe"
Note 5.: Some attention may be necessary when using an asterisk, although I cannot specify where since I do not have multiple graphics cards. Therefore, I recommend consulting the question Running the devcon.exe properly (enabling/disabling the device from command line in Windows 10), which addresses:
devcon.exe disable "PCI\VEN_1002&DEV_687F*"
devcon.exe enable "PCI\VEN_1002&DEV_687F*"
