Compal LA-4092P schematic, revision R1, for the JBK project in its DIS configuration, meaning the discrete-graphics version with a dedicated GPU. The RAR holds a PDF of about 1.8 MB, and its GPU power pages and VRAM sections are useful on boards with graphics failure. Use it to measure rails, follow enable and power-good signals, and find the components behind a short. Check that the PCB reads LA-4092P with a matching revision, and that the board actually carries a discrete GPU rather than the UMA layout.
