BIOS dump for the HP Pavilion 14-ab series, Quanta motherboard DAX12AMB6DO revision D, packed in a 4.25 MB RAR archive. The number follows the Quanta DA-project-MB scheme, where the trailing letters encode the PCB revision; the final O in the name probably stands for a zero. Technicians program this image into the SPI flash with a CH341A or similar tool when the laptop stays black-screened. Verify that the chip capacity matches the image size and keep a copy of the original contents.
