Firmware image for the Acer Aspire ES1-511 laptop, motherboard LA-B511P, distributed in a 2.73 MB ZIP archive. The LA- numbering identifies Compal as the board designer, so the Compal label on the PCB is the reference to compare against. Technicians use such a dump to rewrite the BIOS chip with a programmer when the notebook shows no display, fails POST or is bricked after an update. Read and store the original chip contents first, and confirm the extracted image size equals the flash capacity before writing.
