Hey ya'll, my sister bumped my powerbook off a table and it fell to the ground, smacking on the corner. Cosmetically, just a tiny scratch, and it still works just fine, so no real serious damage. However, the chassis is bent just a bit; it wobbles on flat surfaces. If I push down on the wobbly corners, I can eventually bend it and stop the wobble, but, it is crooked again next time I use it. It's not off much, just a millimeter or two. Is there any way to adjust screws or tension somewhere to level this out?
