BIOS together with EC firmware for Lenovo B51-80, E51-80 and E41-80 notebooks built on the Compal LA-D102P board, in a 4.24 MB RAR. Having the embedded controller code included matters when the keyboard, charging or power button fail because the EC chip is corrupted. Compal uses the LA-xxxxP pattern, so match the code on your PCB. Program the SPI flash with an external programmer, and if the EC has its own chip flash it separately; always back up both originals before writing.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
