OAT YEAH! Followed this guide to replace my Macbook Air 2014 I/O board step-by-step (thx Jeff Suovanen and contributors) with no probs…workie workie now! FYI it had stopped charging…I tried a new charger, new battery, and finally this I/O board…

Just take your time and make sure you have the torx screw + adapter bits and spudger as they do not come with the I/O board (I had them leftover from a previous iFixit battery swap).

Followed this guide step by step for a successful battery swap thanks iFixit!

FYI, as someone else pointed out, if you try removing the battery connector after you have installed it for one reason or another the pins pull out of the plastic connector piece (the adhesive does not hold). You have to push the cable back into the plastic connector so the pins are all the way back in.
