Compal boardview for the LA-M002P mainboard, project code HH51R, with R1A in the name, likely the board revision. It is packed in a 682 KB RAR archive. Compal uses LA-prefixed numbers for boards that end up in laptops from various brands, and the name does not say which model this board went into. Check the number and revision printed on the PCB, then open the layout in a boardview viewer to find components, trace power rails and signals, and locate test points for short diagnosis.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @BoardSchematic. Enginerys does not host this file.
