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

    • 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.

  • When reinstalling the heat sink, be sure to apply a new layer of thermal paste. If you have never applied thermal paste before, we have a guide that makes it easy.
