HP 15-bs526ur LA-E791P Rev 1.0

BIOS .rar 10.9 MB Shared

Firmware dump for the HP 15-bs526ur notebook built on the Compal LA-E791P motherboard, revision 1.0, packed in a 10.9 MB RAR archive. Compal uses the LA-xxxxP pattern for its board numbers, and HP ships this board in several 15-bs variants. Technicians use such a dump to recover a board that will not POST or has corrupted firmware by writing the SPI chip with an external programmer. Check that the PCB silkscreen reads LA-E791P Rev 1.0 and keep a backup of the original chip contents before flashing.
