PDF schematic for the Compal LA-E841P mainboard with project code CTL51, stored in a 1.47 MB RAR archive. The name does not state the laptop brand or model, so identify the target by the board number printed on the PCB. LA-xxxxP is the Compal numbering scheme, and the same board can appear in several retail models. Diagrams like this help trace rails, diagnose shorts and missing voltages, and locate parts by reference designator. Check the revision on the board before relying on circuit details.
