Raven,

This is not for the faint hearted and because there are many types of different hinges used i cant be absolutley specific but here goes any way :)

You will probably need to lift the caseing aroung the top of the keyboard, then the caseing around the screen. There generaly lots and lots of small screws involved and some locking tabs.

I find the best way to deal with the locking tabs is to tease them open with something like a jewellers screw driver and then use

You should then be able to get to the hinges for the screen. The main problem I've seen with loose hinges is the plastic fixes for hinges have broken and the screws have fallen. If this is the case there isnt a great deal you can do other than replacing the screen caseings.

Hope this helps, if you need any more assistance please dont hesitate to ask.

Regards

Nick
