BIOS and KBC firmware set for the ASUS PU551LA laptop with motherboard revision 2.0, stored in a 5.06 MB RAR archive. KBC means keyboard controller, the embedded controller that handles power-on, charging, keyboard and fan control, so both main BIOS and EC images are included. Faults such as no power, no charge or erratic fans can need the EC reflashed along with the BIOS. Confirm the 2.0 revision on the board, match each image to its chip, and back up both chips before programming.
