Moving a Jumper
A jumper’s setting is determined by where the jumper is placed
on the pins. The jumper either connects pin A and the middle
pin (position A) or connects pin B and the middle pin
(position B), as shown below. (The letters A and B are shown
here for position only. They do not appear on the jumper.)

If you need to change any jumper settings, follow these steps:
1.
If you have not already done so, remove the cover and the
subassembly from the computer. See Chapter 5 for
instructions.
2.
To move a jumper from one position to the other, use
needle-nose pliers or tweezers to pull it off its pins and
gently move it to the desired position. Be careful not to lose
the jumper.
Caution
Take care not to bend the jumper pins or damage any
surrounding components on the main system board.
3. Follow the instructions in Chapter 5 to replace the
