Hi @jakejames79879
Here's the [https://dl.dell.com/topicspdf/g-series-15-7500-laptop_service-manual_en-us.pdf|service manual] for the laptop.
Go to p.24 to view the procedure to remove the display assembly. On p.26 it shows the hinges being removed from the keyboard/uppercase assembly.
If the hinges are broken and not the uppercase assembly or lid cover hinge screw mounts, search online for ''1FF93 8FNPP'' to find suppliers of the hinge assembly that suits you best.
