Schematic for a Dell laptop built on Compal board LA-K741P, revision 1.0, supplied as a PDF in a 3.73 MB RAR archive; the laptop model is not stated here. Open it in any PDF reader to follow the power sequence, identify voltage rails and their regulators, check enable signals and read component values. Compal uses the LA-xxxxP pattern for its boards, so confirm the number and revision on your PCB, and combine it with the matching LA-K741P boardview to find parts physically.
