Hi! Paul
You need to disarm the computer, enter Ebay with the serial number and brand of your laptop and buy the pieces that are broken and change them. With the service manual it is easy to disassemble and assemble the computer. Never use glue or other product to stick your machine. Stick does not work specially on the hinges because they are too strong. They are strong for support the weight of the monitor and they will broke again. Sometime if you search well you can find broken used computers for parts at a good price on Ebay.
