Bollocks. It’s the logicboard. While the price to fix it is pretty steep, it’s still a lot less than outright buying a new machine. Thing is, it’s a 6 year old machine. Need some perspective from everyone. Worth repairing or should I just call it quits.
@smokey Well it did make me feel better to some degree. This Air is well travelled - it has crossed the world a couple of time, when I have been back to the UK to visit family - and seen a few OS upgrades. Though I have not upgraded to Catalina yet - initially because of the horror stories that I was reading, and now I am unsure whether I will as I am noticing some slowing in this machine. Nothing to make it unusable, just tell tale signs.
