I have a Compaq Presario M2000. The hinges broke. I did some research and came up with a part number (394305-001). It doesn't fit. The mounting brackets are too short. I contacted HP tech support and all they could tell me was that according to their documentation I had the right part number. Does anybody know where I can find imformation on the dimensions of this part? At this point I don't know if I have the wrong part number or if the part I received was just labeled wrong.
