Hi William,
Thanks for posting in the community. To help you better with detaching the screen, may I know the exact model of your device? This will allow us to provide more accurate steps.
First, you can check your device model by pressing Windows + R, typing msinfo32, and hitting Enter. You can also use dxdiag in the Run dialog to view detailed system information.
Once you confirm the model, I’ll be happy to guide you through the correct detachment process.
Best,
Carl
