Dell X300 hinges

Lately I have been fixing up a lot of Dell X300 laptops to send to Africa.  One of their problems is that the hinges go bad and the screen falls down flat.  As it turns out the fix for that is quick and easy.  Remove the hinges, tap the pin back in with a hammer or on a vice and it works.  The hardest part is getting them out of the laptop to fix them.  Somehow they slowly work their way out then there are no barbs to catch on and they go loose.  They can be fixed while in the laptop but that is dangerous as the wires are in the way.
