BIOS and EC firmware package for the Compal LA-8731P mainboard, identified by the QAU51 platform code. The RAR archive, 4.39 MB, should hold the system BIOS image together with the embedded controller firmware, which together restore a board that fails to power on or loops at startup. LA-8731P follows Compal numbering, so the laptop brand may differ from the board maker. Confirm the board number on the PCB, read and save the original chips with a programmer first, and check each image size against its flash chip before writing.
