Compal-style daughter board schematic for the Alpine IO board, number LS-E541P, project code CIUYA_YB, delivered as a 462 KB PDF. LS-numbered drawings cover the secondary boards that connect to a Compal LA- mainboard, typically carrying USB ports, audio jacks, card readers or LEDs. A technician uses it to check the flex or connector pinout, the supply rails arriving from the motherboard and port protection parts. The laptop model is not given in the name, so match the LS number on the PCB before relying on it.
