PineBook Pro revision 2.2: Wishlist for the hardware issue fixes
Discussion of barrel-jack power connector is very relevant to Pinebook Pro because it was a design flaw.

I think Pine64 should drop all use of them in favour of USB-C -- it was disappointment to me that Quartz64 Model A, a fairly new design SBC, had barrel power I didn't want to deal with it so it dropped out as a purchase. USB-C is standard everywhere so Pine64 ought to be keeping up with the rest of the world. It's Pine64's loss the longer they choose not to adapt and adopt fully.

In this thread we frown on all the errors in Pinebook Pro and wish for updated design.

Double-frown on fact it is still sold in original form without revision.

Presence of a feature that you dislike - whether that is USB-C or the barrel jack - is not a design flaw, it's a design decision that you disagree with. A design flaw is a mistake in the design; i.e. something that the designers did not intend. The designers intended both USB-C and the barrel jack. They did not intend the power circuitry to overheat.

You're free to have whatever opinion you want, but it'd be nice to focus on the core things that everyone can agree are issues instead of wasting time, effort, and energy (your own and other people's) on issues that people will not come to an agreement on.

It is a fact that including both barrel-jack and USB-C on the PBP was a bad design choice. Using both at the same time can be fatal to the PBP.

This thread has been running for more than 18 months and I think people are free to talk, discuss and debate anything they think is an issue or problem on the PBP. That is what being a community is about and it is their effort, time and energy that they take individual responsibility for expending. Even if I disagree, I still respect that. It is fine to disagree.

It is not for you to dictate or even attempt to shutdown what the community discusses, debates or thinks or how.

It's not quite accurate to say that including them both was a bad choice, in my opinion. The bad design choice was not including them safely. (Because, as you point out, they are installed together in an unsafe manner.)

It is an accurate fact that it can be fatal to the PBP if both are connected at the same time but everything else you say is true. May be both power connectors could be accommodated safely but instead a bad design choice was allowed to make it to production. The present situation is worse than having just one of either power connector which would have been the safer path (even if it was barrel).

Including both will just be adding complexity in higher power charging scenarios.

USB PD has logic in it where the laptop and the charger can communicate and switch to a higher voltage if possible. Try to think how you would introduce a second DC port in to this situation and how it will work and at what power etc.
