About this board

Lenovo Chromebook C340 C630 C640 — motherboard LA-G741P.

The board was manufactured by Compal for Lenovo. Compal board numbers start with LA- and end in P, so you can confirm it on the PCB silkscreen.

Files usually needed for this board
  • BIOS (full SPI chip dump, .bin)
  • EC / KBC firmware, if the board uses a separate EC chip
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Typical reasons to reflash: no power or no display after a failed BIOS update, a BIOS/supervisor password lock, or a corrupted Intel ME region.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.

If you have a working file for this board, please share it below. More files: search LA-G741P in File Finder.
