Small Compal schematic for the touchpad button board LS-7073P at revision 01. Compal uses the LS prefix for daughterboards and LA for main boards, so this covers only the button PCB, not the motherboard. At 33.2 KB it probably shows the switches, connector pinout and any protection parts. Technicians use it to check button continuity, trace the flex cable lines to the main board and find a faulty switch. The laptop model is not given, so confirm the LS number printed on the small board before relying on it.
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 @hrtechno. Enginerys does not host this file.
