BIOS and keyboard EC firmware for the HP 15-BW series laptop, platform CTL51, on Compal board LA-E831P revision 2.0 from 2017. Compal's LA- numbering shows it built the board for HP. The 14.8 MB RAR includes both the system BIOS and the KBC/EC image, useful when a dead board needs both the main SPI flash and the embedded controller firmware restored. Back up the original chips first, match the image to the correct chip size, and confirm the board number and revision on the PCB.
