Re: Custom Built On-board PC / Boatputer Advice
A modern laptop, with a modern CPU and OS, is much better at power conservation than an older one. Even Vista has the ability to power down subsystems that are not being used, in order to extend battery life. Now? It is sort of blackmail...You need a 7th Gen Core i7 cpu to really benefit, because you can control how many cores will be used for a task, which in turn will make major power differences. And, the 7th Gen chips will *only* run Win10 (in the MS OSes) which forces you into Win10. Which happens to support new harder (like USB-C) and new i/o controllers that the older OSes just don't and won't support. And Win10 supposedly can control power to unused systems at an even higher granular rate. Some of the Lenono's and others claim to push 13 hours in a slim machine by using all those tricks. (Sure.(G)
So using modern hardware, and SSDs, can really help your game. As to upgrading hardware...yeah, that's a desktop thing. And that really stopped 15 years ago, because other than swapping hard drives? There have been so many basic changes in i/o busses, in memory speeds and form factors...heck even in hard drives, the 2.5" SSDs are half the speed and way more power consumption that the PCI "card" drives that some of the new laptops use. Sadly, simple hardware upgrades buy you less and become less likely every year.
If you can put together a NUC or other light system that does everything you need, great. Bear in mind that even if you get an older Windows OS...when you want to upgrade, it won't be supported in the new hardware. And that of course gets into the cycle of the software expecting to see certain hardware and all the furballs of fun.
A turnkey laptop ain't such a bad way to go. Why they all seem to need 19VDC when nothing inside the box runs at more than 5VDC...damfino, I've been asking that for 20 years and haven't gotten one answer.
