Repair archive for the Dell Latitude E6540 built on the Compal LA-9411P motherboard, labelled as a CD IC bypass. The name suggests a modification that works around the USB Type-C or charger detection controller, the CD IC, so the board can power up without it, though the exact method is only shown inside the archive. Compal uses the LA-xxxxP pattern for its laptop boards. Extract the RAR with 7-Zip or WinRAR, confirm the board number printed on your PCB matches, and study the procedure fully before lifting or bridging any parts.
