Low-power laptop

If you're looking for longevity away from mains power, you should be looking at batteries not laptops. 5v power banks are cheap and suitable for powering any Android tablet. You can also build your own lithium battery pack and output an arbitrary voltage to power whatever laptop you might want.

This. If you can combine that with with some low powered arm based system that's able to power itself on and off or go into sleep mode you can get a computer that runs for days off battery. There are some boards that have the circuitry for connecting, supervising and charging batteries directly on board, cubietruck comes to mind.

Sure, I'll do that in between checking out that cool trick with the hot spoon and blowing magic crystals.

12 volts is 12 volts but it's a terrible idea with something that's capable of dump 600 amps on your port.

Only voltage matters you fucking sped, the powered circuit's resistance limits the current by itself
If you don't know Ohm's law by heart you shouldn't be allowed to post on Zig Forums

Atom's also have the benefit of not being infected with the ME botnet.

I'm not falling for your schemes you tricky chink.

Well then make a project of connecting a keyboard and screen, and 3D print a laptop-like housing for it. You're no fun.
