You do not need to take the entire computer apart. The bezel can come off while still hinged to the main body giving you access to the four screws holding on the display. Unless you need to replace the main display ribbon cable, the screen itself is straightforward to replace.

If you are replacing the bezel at the same time - don't forget to check that the clear film has been removed from the webcam lens. A foggy image is not reassuring when testing the reassembled computer.
