Firmware for the HP 15-bs526ur laptop on Compal board LA-E791P, Rev 1.0, with KB9022D named as the ENE embedded controller. The 5.53 MB ZIP likely holds the BIOS image or the EC firmware for that controller. Such files are written with a hardware programmer to fix dead boards, charging problems or corrupted firmware. Back up the existing flash before writing, check that the image size matches the chip, and confirm the LA-E791P marking and revision on the PCB.
