If I remember correctly , you should keep the gnome alive and clear the path for him so he can activate the console. I don't think you can do it yourself.
The bossfights in Ch.3 are quite brutal. Regularly, half my party was down before I could even act. I switched to explorer mode for these fights. It gives your characters double hitpoints and consequently some more time to put up a fight and get a good survival chance.
