Investigate the New England Technocrat Society

Inside the Harbormaster Hotel, enter the New England Technocrat Society section which is located in front of the elevator.

Examine the Control Terminal

Inside the locked room, access the AI Control Terminal and disable the AI Control System to end the quest.

Do not forget to pick up the De-Capitalist Helmet on the Power Armor frame nearby, as well as the Picket Fences Halloween Special magazine near the terminal to unlock Halloween Decorations for your settlement.
