Working BIOS and EC firmware for the Lenovo ThinkPad E50 on Quanta board DA0GC6MB8F0, revision F, marked as fully tested. DA0xxxMBxx0 numbers follow the Quanta ODM pattern, where the board code sits in the middle characters. The EC image handles power-on, battery charging and keyboard functions, so a corrupted EC can cause no-power faults. Dump both original chips with a programmer first and ensure the board revision and chip capacities match the images.
