Firmware dump for an HP 15 laptop built on Quanta board DA0U8AMB6A0, revision A, with an Intel N3540 CPU, marked as fully working. Quanta's DA0 codes identify the board project and revision, so compare the number on your PCB before flashing. Read and save the existing BIOS chip contents with a programmer first. Then check that the image size equals the chip capacity and write it to recover a board stuck with no display or failing to start after a corrupted update.
