MBP battery replacement: put the I/O cable the wrong way
So the whole proces of taking it apart went pretty smooth and putting it back together felt the same way. However, my MBP with it’s new battery was not booting, even with the battery indicator on.
Taking it apart again showed that the I/O cable that we removed on step 9 was put back the wrong way (180 degrees). This probably resulted in a short circuit with the connector on the motherboard not looking good.
I’m afraid my MBP is dead by now but would really like to get it fixed but I don’t know what would be the best procedure moving forward?
