1 Dead after 6 months... Culprit is I/O Board Cable?
I’ve had this 2017 13 inch macbook air for six months, and now its dead... sort of. One day after it stopped turning on I went through the usual procedure. SMC reset did work according to the magsafe light but the laptop still wouldn’t boot. After trying lots of things inside the machine, I found that if I unplugged the battery and the cable that runs from the top of the I/O Board to the MLB, the machine would boot just fine. I would plug the cable and the battery back in as soon as the fan started spinning. It worked fine for a week or so, then the same thing occurred. Did the same fix and the machine worked for another week. There has been no damage whatsoever to this machine. Any ideas why this is happening?

I would start off checking the battery to see how the charging logic is doing. Install CoconutBattery. Take a snapshot with the MagSafe charger connected and a second one disconnected. Paste both here for us to see 在已经存在的问题里加入图片

mmm ... I see zero watts in both. Lets run the battery down a bit ~15 % and test again.
