Schematic for the Compal LS-4681P board, revision R1.0, packaged as a 41.8 KB RAR file. Compal assigns LS numbers to small secondary PCBs, for example power-button, USB or audio boards, which link to the LA-series motherboard through a flex or cable. The function and laptop model are not given in the name. Technicians use such a drawing to check pinouts across the connector, verify supply voltages reaching the sub-board and test switches or ports. Match the LS code silkscreened on the PCB before working.
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 @abgm_manutencao_bios. Enginerys does not host this file.
