Acer Aspire A715-71 firmware set for the C5MMH platform board LA-E911P, containing both the system BIOS and EC firmware according to the name. LA-xxxxP numbers are used by Compal, the ODM behind this board. Technicians flash the BIOS to the SPI chip and the EC code to the keyboard controller or its flash to fix no-boot, no-power or charging faults after corruption. Confirm the LA-E911P marking on the PCB, back up both chips before writing, and check the image sizes against the chips.
