BIOS and EC firmware set for an HP laptop with service code HSN-Q31C, built on the Quanta X9Q board DA0X9QMB8D0 revision D, archived as a 20.8 MB RAR. Having both images matters because HP machines keep embedded controller code separately, and a corrupted EC can cause no-power or no-charge faults. Flash them with an SPI programmer to the matching chips, checking each image size against the flash capacity. Read and save the original contents first, since serial and activation data can live in the chip.
