15-ay (BDL50 LA-D704P Rev4.0)

BIOS .zip 22.2 MB Shared

Firmware archive for the HP 15-ay series on the BDL50 LA-D704P mainboard, revision 4.0. The archive is fairly large at 22.2 MB, so it may hold several images or supporting files rather than a single dump; inspect the contents before use. LA-D704P is a Compal board number, Compal being the ODM that manufactured this board for HP. Typical use is recovering a corrupted BIOS by programming the SPI flash with a CH341A or similar tool, after backing up the existing chip and verifying the image size matches its capacity.
