BIOS archive for the HP 15-ay series notebook, with the board code given as LA-D702D in the name, which resembles the Compal LA-series numbering. The 3.75 MB ZIP should contain an image for programming the SPI flash when the laptop does not boot due to corrupt firmware. Open it to check whether it is a full chip dump or an update file. Verify the code printed on your mainboard matches, read and save the original chip before writing, and confirm the image size matches the flash chip capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
