Sorry Bug, I didn't mean to cross post like that, but I felt this title would get a better/more responses.
Also, thanks a lot for the response. As I suspected I can just skip the brick completely and use the cable straight from the laptop. Google combinations like "Carnetix to laptop" and visa versa and you'll see what i mean about not being able to find a clear photo/description of what to do.
My Carnetix is providing ample power as tested via the multimeter, so I'll try this out when I get home.
http://www.carnetix.com/installation...anual_V1_2.pdf Look at page 14 in the manual. Connect the red to the + on the plug and the black to the grnd on the plug.
Note there are duplicate red and blacks. You can safely combine both wires together, then solder them to the laptop cable. Get some heat shrink tubing from Radio Shack and slip it over the wire before connecting the for a nice, professional look.
Here's a nice guide on how to splice wires.
If it is a barrel-type connector for the laptop, the outside is USUALLY for ground.
Edit - changed title of thread for OP.
It worked great! Thanks guys!
Would I need to follow this thread's idea to be able to power a standard mini-ATX Shuttle PC? I normally use an Invertor to power my Car PC's for the past 5 years or so, but now I have a 4-door Civic, and an Invertor may not be logical since I'd have to put it in the trunk or something out of reach...
