On the base of your notebook, is there a hatch about 3" by 1½", fixed down with a screw? If you have, unscrew it and reseat the RAM - memory sticks. Be very careful when holding back the sprung metal clips that kep them in place. That can fix this problem but so can many other things.

Does it happen when it isn't only on battery power?
