Dell Inspiron 7520 firmware set for Compal board LA-8241P, containing both the main BIOS and the EC firmware according to the name. The embedded controller handles power-on, battery and keyboard functions, so a damaged EC image can cause no-power symptoms. Compal uses the LA-xxxxP numbering printed on the PCB, so confirm yours matches. Back up both chips with a programmer before writing, and check each image size against its flash chip to be sure it fits.
