Compressed RAR archive of about 790 KB for a Compal LA-7822P motherboard at revision R1.0, labelled for the NEC LaVie LL750 notebook. The name does not list the contents, but Compal archives of this size usually hold a schematic PDF and sometimes a boardview. Compal builds many NEC machines, so the LA- prefix is its own board code. Use it to trace power rails, follow signal paths and find test points, and check that the LA-7822P marking and revision silkscreened on the PCB match before relying on any values.
