My screen was too broken and the suction cup would not stick. I too a piece of Gorilla duct-tape and stuck it to itself and then also to the screen so that it made a "Tab" that I could pull up on. This worked much better than the suction cup.
The tiny "captive spring" came off of the back of the screw and I struggled to get it to go back on. I ended up placing the spring over the hole where the screw goes in, with the holes lined up then putting the screw through both.
Also, the replacement screen I received from ifixit.com was slightly different than the original. The small metal tab where this screw goes in was not slightly bent downward like the original. It didnt make any difference. The screw went back in as normal.
According the tear down the fan just lifts off? No screws or anything to unplug? Thats weird.
