It's the round silver battery right on the motherboard.... unplug the computer first. there is small tab that you move sideways with your fingernail. when that clip is moved far enough the battery will pop out of the holder... to replace the battery put it back into the holder with the round side toward the clip and push down gently... it should snap into place.
