I'm no stranger to not doing a proper tear down, sometimes it's easier that way. When I did the hinge fix on my eMate I definitely did not do all the steps. (Alas, my ingenious idea of using 5W-30 for hinge lubricant only lasted a year).

Lol, the manual says that for vertical bars I should replace the logic board. Okay, Apple, I'll just go drop this off at the Genius Bar Saturday.
