I lost this screw! How important is it? Will it be okay with just the 3 previously removed screws?

Carefully lift the battery connector board up off the logic board. It is recommended to bend the battery cables just slightly, to keep the board suspended up above the logic board and out of the way.

    • Removing this board will ensure that the battery remains disconnected throughout your repair, preventing your computer from accidentally powering on. It's also a good idea to take it out so it doesn't fall out unexpectedly.

WHy to remove battery contact board? Replace can happen without it also, right.

when reinstalling the interposer - pay close attention to proper orientation. You can install it upside down and still make it fit - don't ask me how I know!

Also found the rubber caps on the 4x2.7mm - didn't bother to replace the caps and didn't have any problems with them.

Use the tip of a spudger to flip up the retaining flap on the left fan ribbon cable ZIF socket. Be sure you are prying up on the hinged retaining flap, not the socket itself.
