Yes, I did. It did not work.Did you turn off PowerNap for both Battery and Power Adapter? I don't know if it matters, but I turned off PowerNap using this command, instead of the UI:
sudo pmset -a darkwakes 0
Maybe try that and see if it works?
After reading the many posts about this issue in the Apple Community forum, I noticed that a couple of people mentioned a dock in their post, and that they've had trouble w them. I have a dock. Mine is the OWC Thunderbolt 3 Dock, which I've now detached and I'm using the MBP charger. I've also connected my desktop monitor and an Anker USB-C hub to connect an ethernet cable. We'll see how that goes.
As I mentioned in my original post, my 2018 15" blew up a little bit over a week ago, right after the 10.15.4 supplemental update installed. Since I didn't know exactly how long it would take Apple to repair the 15", I bought the 16". As it turned out, the 16" and the repaired 15" arrived on the same day.
Prior to the explosion, the 15" had been plugged into my dock for the better part of a year. Not all the time, but much of the time.
I'll chime in with an update tomorrow. Thanks for your input.
