Where can I download free schematics dia...

Hello! Can you help me solve my problem? They keypad of my Asus V66 phone is difficult to turn the switch on and off. My friend told me that one of the connections of the keyboard is detached and it needs to be put back in. My problem is that, my friend does not want to touch the circuits because he wants to know where the connections really are. Can you help me solve my problem? I need a Asus V66 Schematic Diagram where it is indicated there what are the wires that is damaged and what are the things to be done in order to fix it. I do hope you could help me. Thanks.
