BIOS dump for the Lenovo U30-70 laptop built on motherboard LA-C311P, a number following the Compal ODM pattern in which LA codes identify the board design. The rar archive is about 3.66 MB and the name gives no BIOS version or ME status. Repair shops write such images with a programmer such as a CH341A to revive boards that fail to post after a bad flash. Before writing, read and keep the original contents, check that the LA-C311P marking on the PCB matches, and verify the image size equals the chip capacity.
