Step 9
Battery Contact Board
- Grasp the Interposer with tweezers.
- An interposer is the name for an interface that links one electrical connection to another. In this repair, it is the board connecting the battery to logic board.
- Lift the Interposer off the logic board and remove it.
- 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.

NOTE: The logic boards you are placing into your Macbook Pro as a replacement probably are not coming from systems that are current and actively being used (they may have been on the shelf for a while)…more importantly they are almost certainly not coming from systems that were fully updated and running MacOS High Sierra. Realize that if you have updated your Macbook and are running High Sierra, your hard drive has been converted to the latest APFS Apple file system. In order for an older logic board to be able to read any of your APFS hard drive will require that the logic board gets the latest SMC/firmware updates. Without this you will not be able to boot from your hard drive. See how I was able to correct this dilemma here: Hard Drive/OS not recognized after logic board replacement
