Instead they rewrote the appropriate section and asked if it now answered the question. The result was the best architectural description of a computer ever produced.

My MacBook Pro doesn't keep accurate time without a continuous connection to a NTP source. When I'm at home, that comes via Comcast, which requires mains power, and will probably fail for other reasons as well. In the field I use my cell phone, which has the same problems.

The backup battery should be relatively easy. One solution just powers the single board computer and not the monitor. Then the user knows power has dropped.

To me, an FAQ is answering questions raised because the Rules are poorly written or incomplete. If I were running things, I would ban all FAQs and tell the author(s) of the basic document(s) to finish their job!

The bad thing is that independent of the mains AND not powered by a generator is that most laptops now need 16-20V at their power socket, it's hard to find QUIET DC-DC converters, and it probably takes more power to run the laptop than to run a KX3.
