Firmware image for an HP 15 laptop built on Compal BDL51 board LA-D711P, revision 3.0, in a 3.18 MB RAR. It is meant for programming the SPI chip directly when the notebook will not boot, shows a black screen or is stuck after a failed update. BDL51 is the Compal project code and LA-D711P the board number. The name does not say whether the dump is clean, so save the original chip contents first, confirm the board revision, and make sure the image size equals the flash capacity before writing.
