Computer Science degrees are math degrees. Yes, I've worked with a few of the pure, theoretical types, but your typical CS students are pretty good dealing with tech problems as well - as they get asked by everyone they know to deal with them. CS majors, in real environments, often need to get hardware and software to work together though.
The reports I received is that the Mac Mini power light was on and that was it. Nothing to the monitor. No chime, etc. A guy at the Apple Store told me that he had a PSU issue with a new 2018 Mini. I described my problem to him and he said to bring it in. The other guy I spoke to there said that they've had cases similar to mine so it may very well be a hardware problem caused by a software upgrade.
I read about the Chrome update problem - Google's fault.
