Schematic for a small daughter board, the Alpine sensor board numbered LS-E543P, with the project code CIUYA_YB in the name. The LS-xxxxP pattern is used by Compal for secondary boards such as sensor, IO or power boards, while the main board uses an LA- number. The 392 KB PDF shows the connector pinout to the motherboard and the sensor circuitry, useful when a lid or sensor function fails. The laptop brand is not stated, so confirm the LS number printed on the actual board before use.
