Reading the many posts on this issue as well as the many other reports outside of the Apple forum, is aggravating. My MBAir, new in late summer of 2019 has the same problem. I had just arrived in Thailand, entering into a mandatory two-week quarantine in a hotel, thus particularly dependent on a working computer, and the same thing happened--just out of the blue it was totally non-responsive. First, I sent the hotel clerk to a nearby apple store for a new power adapter, then had them take the computer in for diagnosis, and the failed logic board was the immediate response. To add insult to injury, the design of the SSD means it cannot be saved, and the data is lost. Fortunately, I did have a time machine back-up, albeit several days prior. I believe Apple is negligent in failing to acknowledge, report, and recall these models, and I am now struggling with them on successive calls to Apple Care to get them to step up to the plate to 1)get an estimate for the repair time frame, 2) give me back the SSD or logic board, which has my data (for security purposes and the fact that I own it) and 2)provide me immediately with a replacement, which they have refused! So, if enough of those of us who have been harmed by this problem make ourselves known, we might get them to listen!
