Firmware package with BIOS and EC images for the HP 15-ay004ne laptop on Compal board LA-D703P, compressed into a 4.40 MB RAR archive. It is used to restore a board that will not power on or boot by rewriting the SPI flash with an external programmer. LA-xxxxP numbers mark Compal designs, so check the code and revision printed on the PCB. Back up the original chip, which may hold serial data, and check that the image size equals the flash capacity before writing.
