Lenovo's stock documentation applies to all of their ThinkCentre computers, so it's pretty vague. It indicates that a jumper needs to be moved but doesn't indicate which one. The hardware and maintenance manual for the unit does not contain any info on this.
It's in the same spot as the M710Q. If you remove the cover, and hold it with the rear ports at the top, it's the jumper in the upper-left corner. It has to be moved down from the top two pins to the bottom two pins, on the left side.
