Small 359 KB PDF schematic for project hh53a, sub-board ls-l974p revision 1A, dated 0124 and tagged CSD. In Compal-style naming LS numbers usually designate daughter boards such as I/O, USB or power-button boards, which fits the small size. The file accompanies the main board drawing of the same project and helps trace connections between the daughter board and the mainboard connector. No brand or laptop model is given in the name, so verify the LS number and revision on the actual PCB before using it.
