Firmware set for the Lenovo Y400 laptop built on the Compal LA-8691P mainboard, containing BIOS together with EC (keyboard controller, KBC) firmware according to the name. Packed as a 3.33 MB RAR archive. Useful when a board shows no power, no display or keyboard faults caused by damaged BIOS or EC contents. Compal uses the LA-xxxxP numbering for its board designs. Verify the board number on the PCB, back up the existing chips with a programmer, and flash each image only to its matching chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
