If there are only two pins, and the jumper was originally attached to only one pin, attach it to both pins. If your motherboard has a third pin next to the jumper, attach the jumper to the second and third pins. If you can't get a good grip, use a small pair of needle-nose pliers, but first discharge the pliers against the case. Remove the jumper from the pins with your fingers. Repeat this step any time you're about to touch anything on the motherboard. Discharging the static prevents damage to the motherboard and other components. Some motherboards may not have a CMOS jumper, in which case you can remove the battery as described later in the steps.ĭischarge any electrostatic charge in your body by touching an exposed metal part of the case. A jumper is a small square of plastic attached to one or more pins. If you don't have a manual, look for a jumper near the CMOS battery or CPU that's labeled "CMOS," "CLEAR," "PASSWORD," "CLR CMOS," "JBAT1" or something similar. Check the motherboard or computer manual to see if your motherboard has a jumper you can use to reset the CMOS settings.
