There aren't any really. You have to replace the entire housing which is almost always a giant PITA involving removing the display panel and then rerouting all the cables once you get the new one. This is a very significant and involved repair, so if you don't consider yourself very good at this kind of thing, don't even attempt to undertake it.
The plastic around the hinges of my laptop has cracked. Does anybody have any good ideas on repairing it? Right now I can't open or close the monitor and it can't support itself.
