To move a jumper from one position to the other, use your
fingers or needle-nose pliers or tweezers to pull it off its current
pins and gently move it to the other position. Be careful not to
lose the jumper or leave it out of the computer. Also take care
not to damage any surrounding components on the main system
board.
Checking the SIMM card jumper setting
If your dealer has installed SIMMs for additional memory, you
may want to check the jumper setting on the SIMM card inside
your computer.
