Schematic for the Compal LA-1091 laptop mainboard at revision R1B, archived as a 2.41 MB RAR file. The LA- prefix is Compal's own board numbering, used on boards the company built for several notebook brands, so the retail model is not stated in the name. After unpacking, the pages help with checking power rails, tracing clock and reset lines and finding the parts behind a shorted rail. Make sure the board code and revision on the PCB match R1B before relying on component values.
