Cleaned ME BIOS for the Acer Aspire 5742 on the Compal LA-5892P board, archived as a 1.71 MB RAR. A cleared Management Engine region is often used to cure boards that power-cycle, shut down after a while, or fail to start after a bad update. Flash it to the SPI chip with a hardware programmer after saving the original dump. Confirm the Compal LA code on the motherboard and that the image size equals the chip capacity.
