Firmware dump for the HP Envy 4 using the Compal board LA-9512P, provided as a 3.77 MB zip archive. Compal assigns LA-xxxxP codes to its laptop board designs, and HP Envy and Pavilion lines were frequently built on them. The image is meant for restoring the BIOS chip with a hardware programmer when the notebook powers on without display or fails to start. Check that the LA code on the PCB matches exactly, dump and keep the original chip first, and ensure the image length matches the flash capacity to avoid a failed write.
