BIOS archive for the HP 255 G5 laptop with the Compal LA-D711P mainboard at revision 1.0, following Compal's LA-number board scheme. The 3.17 MB RAR contains firmware for reprogramming the SPI flash when a unit has no display, will not power on properly, or has a failed update. Write it with a CH341A or a similar programmer. Make sure the board label and revision match, check that the image size matches the chip, and save the original contents beforehand.
