Short PDF schematic, about 81 KB, covering embedded controller circuits on board La-B091, naming both the Nuvoton NPCE288NA0DX and ENE KB9012 controllers, which suggests two EC options or a comparison. The LA-prefix code follows Compal numbering. Use it to verify EC supply rails, crystal or clock, SPI flash wiring and power button signals on a no-power fault, or when swapping or reflashing the EC. Check which controller is actually fitted on your board and confirm the LA-B091 marking before probing.
