Alright, this is a bit of an extreme one, but I need some creative answers. I want to know if there is ANY way to adapt a notebook battery, or any battery for that matter, to run a standard atx case. I know there aren't any conventional methods, so is there any unconventional method that anyone here can think of? I want to be able to build a "notebook" out of standard parts. I have everything else figured out, except for the battery power issue. Any ideas would be greatly appreciated.

your a silly goose

Joey's right! it can be done... but not efficiently. the problem lies in a few places, but primarily, the battery technology isn't quite good enough. It all really depends on the application. It's conceiveable that you might run a standard system, (albeit a low-powered one) within say, an automobile, but the problem there is that your run of the mill parts are quite likely to become toast if you hit a pothole at any amount of speed. You asked, so I'll tell ya... You could run a car battery with a converter to run the standard 120vAC system off of the 12vDC battery... it wouldn't last long, but you might be able to boot the thing... This wouldn't be the type of thing you take to the park and type on though, you'd have some problems just lugging the thing around! As much planning and effort as it would require to make it feasable, you might as well go onto e-bay and find yourself a relatively nice, cheap notebook.

There are a few motherboards that will run from 12 volts. The motherboard in the PCBook will run on 12v (BKi810). This is a micro AT motherboard, no expansion slots, socket 370. I believe VIA also makes some. Otherwise use a 12vdc to 120vac inverter.

I actually already have my notebook running off an inverter in the car. And, I've tried it out and my pc's power supply will run through the inverter as well. I just want to make it work away from a power source. I know, I'm either crazy or just plain stupid. I know I could just get a simple notebook...but I want to do this more or less to prove that it can be done. I'm going to check out the motherboards you suggested Fred. Thanks everyone for their input.
