BIOS archive for the HP ProBook 4420s with an Intel Core i5. The word display in the name suggests the dump relates to a display or no-video fault, though the exact meaning is not stated. The ZIP is 3.83 MB and may hold more than one file, so inspect the contents first. Use it to reprogram the SPI chip with an external programmer when the screen stays dark after power-on. Back up the original chip, check the board code on the PCB, and confirm the image matches the flash size.
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 @bios_laptop. Enginerys does not host this file.
