Circuit schematics for the Compal LA-7983P laptop motherboard, revision R0.3, in a RAR archive of about 1.26 MB. No brand, model, or chipset is mentioned in the name. LA-numbers like this one are Compal's internal board identifiers, printed on the PCB near the edge or under the memory slots. Use the diagrams to locate a shorted rail, check power-good and enable signals, and confirm the pin assignment of a connector. Make sure the revision on your board matches R0.3, because component values can change between revisions.
