flickering display

hi, periodically the display of my last generation powerbook will flicker- a slight variation of brightness appears and goes back and forth a few seconds and then disappears until a later time.
cause for concern?

thanks,

tom

in my opinion its a cause for concern.. do you have a warranty? get to an apple store and have them take a look at it.
