Macbook Air 2015 won't power on with battery plugged in

Hi, I'm having similar problems, same model MBA, telling me the battery is to be replaced, I did this, same symptoms.!!!

I then replaced the logic board with a known good one!! Still the same. Also exchanged the Power board, no difference.

So I did some digging found that the charging control chip may be faulty?

The supplier agreed to find a tested logic board & send to me, ariived today!!

Reassembled the MBA, guesswhat, still the same...............at wits end!

Any likely suggestions?

N.B.

It will start with battery & power disconnected, power reattached

starts without touching the keyboard, reconnect battery, remove power

runs a treat, just closing lid, no shutdown, keep charged, behaves

properly, back at square one!

Also done SMC PRAM several times!

HI having asked for help with this I have now found the answer, remove the battery, check the keyyboard cable where it attaches to the keyboard, I did it had some minor corrosion on it!!!

Careful scraping under magnifier, replace it, IT ALL WORKS NOW!!!

If the corrosion is bad a new cable from eBay or similar will correct this fault probably.
