To fix your problem, try the simple but useful trick of removing and replacing the battery. If no go, try leaving the battery out for an hour or even overnight, before replacing.
Make sure before removing the battery, that the phone is powered off.
You could try a Hard/Factory Reset as described here, using the Button Combination option, but you will lose all your personal data that you have not backed up.
If you can get into Recovery Mode you would be able to select something other than Hard or Factory Reset, but I'm not sure that you can normally get into Recovery on the Xperia M.
