Replacing the batteries is probably part of it. Pulling and reseating is
often not enough though. You must use the old "pink pearl" trick. The
pins must be shiny silver not dull grey. Rub an eraser gently along the
pins to remove the age old grime. (don't use the gritty ink erasers they
will remove the plating, we don't want that!)  BTW in my experience this
works better than all the cleaning liquids one might try.
