BIOS and EC firmware set for the Acer Aspire 3830TG on Compal motherboard LA-7121P. The EC image is for the embedded keyboard controller, which on Compal boards handles power-on, charging and fan control. Reflashing it can cure no-power faults where the BIOS itself is intact. Program each image to its own chip or region with a suitable programmer. Verify that the board number matches the PCB, back up the originals and make sure the file sizes match the chips.
