PDF schematic for Compal laptop board LA-G717P, in the UMA variant, meaning integrated graphics only with no discrete GPU. The file is 1.87 MB. LA-xxxxP numbers identify Compal designs used by various laptop brands; the name does not say which model. Use it to trace power rails, the charger and EC circuits, the power-on sequence and signal paths during diagnosis. Discrete-graphics versions of the same board differ, so confirm that the board is the UMA build and that the number matches.
