1. Power the computer down,
2. remove power cable (and other cables that can carry electricity)
3. and let residual charge drain.
4. Open lid and remove the green jumper.
5. Reboot and you’re done. Maybe you want to put the green jumper back not to lose them (you can also apparently leave it attached to pin 1 or pin 2, but not connect both pins).
