Schematic diagram for the Compal LA-A961P motherboard, delivered inside a RAR archive of roughly 3.1 MB. No laptop model or revision is given in the name, so match the board number printed near the memory slot or on the silkscreen before use. Compal schematics usually cover the power sequence, charger, VRM, EC and all interfaces page by page. Technicians read them to work out the expected voltage on each rail, find the enable signals and decide which IC to measure when a board stays dead.
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 @fixtronix. Enginerys does not host this file.
