Hi, I have a Latitude C400 and have found that the left hinge has started to crumble away. The LCD screen is okay it is just the hinge area that is a problem and thus a new frame is required. I asked the local service center but they could only provide me with details on a replacement display (ie LCD screen and surround). Can anyone tell me if a) possible to replace the frame only, and b) if so, the part number for the display frame? Thanks for the help.
