Schematic for the Compal LA-6881P mainboard at preliminary revision R0.3, provided as a 2.94 MB RAR archive. The name does not identify the laptop brand or model; LA codes are Compal's own board designations. Pre-release revisions may differ from shipping boards, so compare the revision printed on the PCB and treat component values with care. Extracted, the document lets you trace the power-up chain, find enable signals for each regulator, check EC and SPI connections and pinpoint which rail a shorted capacitor sits on.
