RAR archive for board LS-2114, version 04, dated 0828, about 313 KB. The LS-xxxx designation follows the Compal convention, often used for daughterboards such as I/O, audio or power button boards rather than the main board. No brand or device is stated, so open the contents to identify the host laptop. The schematic helps trace connector pinouts, signals and power lines between the small board and the motherboard. Check the LS number and revision printed on the PCB before relying on it.
