Compal schematic for the ZSO51 project, board LA-A996P, marked ULC AMD DIS, indicating an AMD platform with discrete graphics. The 811 KB PDF opens in any reader and helps trace power rails, follow GPU and CPU supply circuits, locate the BIOS chip and identify test points when hunting shorts or missing voltages. Compal LA numbers identify the PCB design, which may appear under different notebook brands. Check that the LA code and revision on your board match, and confirm whether your unit actually has the discrete GPU before relying on those pages.
