BIOS together with keyboard EC firmware for the Acer Predator PH317-51, board code C5PRH, in a 4.87 MB RAR. Having both images matters, because many Acer notebooks keep the embedded controller code on a separate chip or region. A fault there can cause no-power or keyboard and charging faults. Flash each file to its matching chip with a programmer, keeping backups of the original contents. Check that every image size equals the target chip capacity, and confirm the board code before writing.
