Firmware archive for the HP 15-ac108nx laptop, a RAR file of roughly 16 MB. The file name states only the model, with no motherboard number, revision or BIOS version, so the board printed on the PCB should be identified and compared before anything is written. An archive of this size likely holds a full SPI flash image, used when the system powers on with no display or is stuck in a boot loop after a failed update. Unpack it, verify the image matches the capacity of the installed flash chip, and back up the original contents with your programmer first.
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.
