Well put.

Though I’ve had little trouble using other power supplies across brands, so I wonder of this is a single HP line.

I’ve never run across this in business models - if the barrel fits it works, but each brand used their own barrel design, whether that was a different size or a pin in the middle.

And I’ve worked with many brands since the mid 90’s - I’ve deployed thousands of machines over the years - not to say I’ve seen all of them, but a lot of the major brand’s business models.

Consumer models are just garbage, so if this happens there I’m neither surprised nor concerned. I never buy consumer models - they’re garbage, and cheaper for that reason.

And now C is resolving the issue.
