its a piece of a notebook particularly where hinges are attached to the case, but the design is so bad that hinges are not reinforced and are just attached to the crappy bendy plastic, as a result, opening and closing the laptop bends the plastic at spots where hinges are attached and over time it will wear out and crak. Thats a more basic explanation i guess. so as not to cluttter peoples brains, i just stripped it down to the core problem which is bendy bad quality plastic, needs to be reinforced to keep from bending. And so far epoxy along with maybe some other materials like small pieces of plastic or aluminium.
and now my friend told me of another thing i should watch for as epoxy contains toxic cancer causing substance known felonom oe fenom. apperentley its in tiny harmless quantities in every plastic thing out there, but epoxy has a lot of that stuff and he says its a bad idea to use it inside of the notebook since the heat from it will cause microscopic particles of felonom to evaporate and its a serios risk to my health. i searched the internet looking for clear evedince of this and didnt find anything. so i dont know if what my friend tells me is bs or not. but i dont know of a better alternative than epoxy so far. besides i used epoxy often from time to time and i am sure i exposed myself to a lot more harmful stuff and using epoxy wont make any difference to me. (i live next to a nuclear reactor facility so really? epoxy?)
dont hate people who rip you off,cheat and get away with it, learn from them
