I/O Board replacement

My Problem

My MacBook Air stopped taking charge and died. The charger connector stopped lighting up (neither green nor amber) The charger is good as it works fine with my other MacBook Air. So, I suspected a bad I/O board.

My Fix

I ordered a new I/O board and followed the iFixit instructions to replace it. But, unfortunately, that did not fix the issue so I believe my logic board is the problem.

My Advice

The instructions were excellent, as usual. I would only like to have tips on how best to reconnect those tiny connectors.
