BIOS and EC firmware for the HP 15-CW0001UR laptop on Quanta board DAG7BFMB8D0, revision D, in a 4.48 MB RAR. The DA prefix with a project code such as G7B is the Quanta board numbering scheme, and the revision letter should match the PCB silkscreen. Having both the system BIOS and embedded controller images helps fix no-power, no-charge and no-display faults caused by corrupted firmware. Program the flash with an external SPI programmer after saving the original dump, and confirm the file size matches the chip.
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.
