Firmware archive for the HP ProBook 450 G2 on Compal motherboard LA-B181P, intended for reprogramming the system BIOS flash. Compal designed this board for HP and uses the LA-xxxxP numbering. A dump like this helps when the laptop powers on without display, cycles endlessly, or was bricked by a bad update. No revision is stated, so compare the image with your board markings. Back up the existing chip first to preserve serial number and product data, and verify that the file size matches the SPI chip.
