BIOS image archive for the HP 15-bs526ur notebook built on the Compal LA-E791P motherboard, revision 1.0, supplied as ZIP at 5.47 MB. Compal identifies its boards with the LA-xxxxP scheme, and HP used this design across several 15-bs configurations. Technicians write the image to the SPI flash with a programmer to revive a board stuck at black screen or boot loop. Compare the LA number and revision printed on the PCB, back up the original chip including its serial data, and check that the image size matches the chip.
