I think there is only the HCL. You can also subscribe to the qubes-users mailing list since that’s where people usually submit the HCL results. Or look in the archives for similar models.
You can also try one other thing:
- testing Qubes 4.1 (still not ready for regular usage, but worth a try to see if it will support your laptop). An ISO is available here.
