But I don’t have the headphone’s board anymore, so I can turn the on/off. I guess that I need another solution, if there’s one.
The jack shorts out the ground and "switch" pin when it is in circuit. When you remove it, you reopen that connection and need to close it again on the motherboard if you remove the headphone board.
