I just took my powerbook into the apple store because it had a wobble and didnt balance proporly and because the one side of the screen comes up higher than the other when closed. The lady at the genious bar took it to the back and didnt somthing to it and when it came back the wobble was gone but now the other side comes up when closed. i asked her what she did and she said it was a secret. any ideas on what she did? so i can maybe fix the other side.
