A client of mine lost all his files when his hard drive died. I wanted to surprise and delight and get it done before his trip. also I wanted to tighten the hinge on his display so it would stop flopping around
The repair was so simple. I didn't use any repair manuals for the display hinge and I think I'm going to do that today. I got very nervous when after the repair the computer wouldn't boot at all.
1) use the correct power coward. I used the MacBook Air power supply which is weaker. Simple mistake, easy solution.
2) don't try to over torque the screws. I already twisted one of my bits. Better the bit than stripping the screw head or thread though!
