BIOS firmware for an HP Pavilion 15 built on the Compal LA-D703P board, delivered as a 4.61 MB zip. No revision or version is stated. The neighboring LA-D704P is a different board, so the number printed on the PCB must match exactly. Compal uses the LA-prefix pattern for its laptop mainboards. Repair technicians program such images into the SPI flash with a programmer such as a CH341A to recover dead or bricked units. Keep a backup of the original dump and verify the image fits the chip size.
