The March 2015 update of Apple's 13" MacBook Air features fifth generation Intel Core i5 and i7 processors, resulting in slightly increased performance and battery life.

Io board ribbon turns off the computer… help…

My 13” Early 2015 MacBook Air stopped working. Not charging either. The symptom- it’ll turn on just fine when plugged in- and the io ribbon is disconnected. Once connected- the screen shuts off. The battery is also disconnected.

I’ve tried several power supplies, I replaced the io board, the ribbon, cleaned a bit of corrosion from the bottom of the Logic board using deoxit, still nothing works.

I would replace both the I/O board and its cable. You likely have a sort in the board. This board has the audio DAC (Cirrus chip)
