Wistron Colossus schematics covering 15 and 17 inch versions, with DIS OPT indicating the discrete graphics option, revision R1. The 2.30 MB RAR archive holds the circuit diagrams, usually in PDF form. Technicians use these to follow power rails, check the GPU power stage, trace signals and find the parts behind a short or no-power condition. Wistron code names do not reveal the final laptop brand, so match the board number and revision printed on the PCB, and note UMA boards differ in the graphics section.
