OK, so I installed the new fan and sleep light. Both work wonderfully. Seems like the old sleep light was borked even though the IR was recognized in system profiler. The fan is much better than the old one.

As for the new top case, everything is perfect but I did not install it for there is a noticeable (albeit small) scratch on the screen. The Screen I am using now has a few/ pressure marks on it, but they are very faint, the other screen has no pressure marks but a scratch. I am also going to perfect the apple with some red filmy stuff you find at art stores, because the red packing paper look pink when it glows. And I do not want that :

I still have one outstanding problem, sleep takes like 10 seconds to actually sleep. It is already out of safe sleep mode, any ideas?
