Schematic archive for the Wistron Hellcat 15 UP design built on the TGL platform with DG1 graphics, board number 19B31-1. TGL presumably means Tiger Lake and DG1 is Intel's discrete graphics chip, but the name gives only the codes. The RAR is 530 KB and contains a PDF. Use it to follow the power sequence, CPU and GPU rails and connector pinouts. Compare the PCB silkscreen with 19B31-1 before working from it, since Hellcat variants differ.
