BIOS and EC firmware pack for the Acer Predator Helios 300 G3-571, built on the Compal LA-E921P motherboard. The RAR archive, about 4.87 MB, should hold both the main system BIOS image and the embedded controller firmware, useful when a board fails to power on, loops, or shows keyboard and charging faults. LA-xxxxP numbers follow Compal's scheme. Confirm the board number printed on the PCB, read and save the original SPI chip with a programmer first, and check the image size matches the flash capacity before writing anything.
