This is a few months late, but maybe it will help someone.
Being fairly clumsy, I was glad to find this simplified procedure:
1. Disconnect the power cable.
2. Take out the battery. (I replace the battery cover loosely for stability of the case.)
3. Press and hold Fn, D, and M
4. Insert the power cable.
5. The English menu will pop up. (Release the keys.)
