For this guide, we're gonna assume Windows is already on this laptop, as otherwise creating this SSDT is a bit more difficult.
Now open DeviceManager, and head to the following:
Device Manager -> Display Adapters -> Properties -> Details > BIOS device name
- Note some GPU ACPI pathing may be hiding under "BIOS device name"
From the above example, we can see our display is hooked up to
Now that we have our ACPI path, lets grab our SSDT and get to work:
By default, this uses
PCI0.GFX0 for the pathing. you'll want to rename accordingly. For this example, we'll assume your pathing is
External (_SB_.PCI0.GFX0, DeviceObj) <- Rename this Scope (_SB.PCI0.GFX0) <- Rename this Device(_SB.PCI0.GFX0.PNLF) <- Rename this
Following the example pathing we found, the SSDT should look something like this:
External (_SB_.PCI0.GPU0, DeviceObj) <- Renamed Scope (_SB.PCI0.GPU0) <- Renamed Device(_SB.PCI0.GPU0.PNLF) <- Renamed
With the SSDT done, you're now ready to compile the SSDT!
Once you're done making your SSDT, either head to the next page to finish the rest of the SSDTs or head here if you're ready to wrap up:
