Is the hinge broken? If so you will need to take the computer to an authorized service center.

Then take it to an authorized service center. If it won't open there is something physical that is preventing it from opening.

I think we are not talking about the same thing. How could connecting a mouse prevent you from opening the computer?

Are you really having problems booting or starting up your computer rather than opening it?
